Abstract

The plug connector proposed is particularly suitable in all phases of tooth-replacement work, from the taking of impressions of implants (1) inserted in the jaw bone (K), to the production of the master model and finally the fixing of a supra-construction on the implants (1) in the patient's mouth. Use of the connector considerably facilitates the work for the patient, the dentist and the dental technician. The main components of the connector are an anchor pin (100) with an elastic clamp head (130), and a contoured element fitting the anchor pin. This contoured element, a snap-in shoulder (307) for instance, is located in the other part of the connector, i.e. in the impression cap (300), the crown cap or a secondary element (8). The secondary element (8) can be inserted in the implant (1) or in a manipulatory implant, or can be a fixed constituent of such implants.

Description

Ve-rbindunσsannrdnunσ for implant-supported Zahnersar?

The invention relates to a connecting arrangement for implant dentistry according to the preamble of independent claim 1, can be used to Abdrucknah¬ me, manufacturing the master model or attachment of a superstructure on the inserted in the jaw bone implant.

is in the design, materials research, the Instru¬ ment arias and implanting techniques have already made great progress, so that nowadays success rate very high Er¬ recorded and decide roots with missing teeth or no longer existing tooth more and more people, to make use implants. People like Der¬ affected can significantly improve their quality of life with implants. Prior to insertion of dentures or individual artificial teeth intraoral geometry by means of an impression-taking has to be origi- nalgetreu transferred to a master model. The present invention deals with a Verbindungs¬ arrangement that allows on the one hand and the impression taking zahntech¬ African processing considerably simplified and on the other hand to the patient a precisely aligned, structurally simple, but reliable and cheap in addition kosten¬ implant dentistry.

FIGS Oa to Oc illustrate a conventionally common arrangement and procedure in the impression taking, as for example, by Schroeder, A., inter alia, in: oral implantology. Is described Georg Thieme Verlag, Stuttgart, 2nd ed., 1994, pp 209 et seq.. Figure Qa

In the upper or lower jawbone, the implant is K 1 - here a perforated hollow cylinder implant - intraossal and transgingival used, so that the implant head 11 penetrates the mucous membrane S. The example described relates only to an implant 1. In a umfassen¬ their supply even more implants 1 can be set so that the dental structures multiply accordingly. After 3-4 months of healing of the implant 1 are no longer visible here inputs heilkapppe was removed, and the octa-secondary part 2 is screwed into the implant in situ. 1 Thus, the base 21 of the cone-octa secondary part 2 is seated in the implant cone 12 and the thread segment 22 of the octa-secondary part 2 engages in the threaded bore 13 of the implant. 1 The threaded bore 13 extends from the area of ​​the implant cone 12, from the bottom surface axially downward. The Octaseg ent 23 of the octa-secondary part 2 protrudes beyond the implant shoulder 14 on the implant shoulder 14, the irreducible Ab¬ is pressure fitted cap 3 with its opposing shoulder 31st The impression cap 3 is screwed by means of this axial durchdrin¬ constricting positioning screw 4 with the octa-secondary part 2 by the threaded segment 41 of the positioning screw 4 into the blind hole-shaped threaded bore 24 in the

Octa-secondary part 2 is engaged. For Octasegment 23 3 complementary inner contours are provided on the connection part 32 of the impression cap, so that the parts form a form-locking connection. Dr'ehinstrumentes for the engagement of a one having the positioning screw 4 on the screw head 42 has a Phillips-head 43. At the to ver¬ caring jaw line and the impression cap 3, a with A bdruckmasse 5-filled impression tray 6 is set, which at its apex a passage 61 for the screw head 42 and be¬ sitting for the escape of excess impression material 5, which is displaced to the jaw line during pressing of the impression tray. 6 The impression cap 3 has the typical angular se outer contour with a plurality of external and spaced-apart ribs 33 to promote the bond with which the impression cap 3 Abdruck¬ surrounding earth. 5

Figures Qb and Oc

Here is the rest of the procedure is evident. After the setting of the impression material 5 of the heraus¬ from the passage 61 swollen Massepfropfen 51 must be removed to expose the screw head 42 to be able to unscrew the positioning screw 4 from the octa-secondary part. 2 Only now can the impression tray 6 with the firmly embedded in the mass media publication 5 impression cap 3 Remove from the mouth of the patient. In the impression material 5, the Kon¬ structure of the jaw line is negative shaped.

For the rest of the description the following applies Fest¬ interpretation. Are in a figure for the purpose of graphical Ein¬ ambiguity reference numerals include but are not explained in the directly associated text description, reference is made to the mention in previous figure descriptions Be¬ train.

Figure Oc

The now inserted in the impression cap 3 Manipulierimplan- tat 7 is arranged at its head 71 as well as the

Accordingly, the implant head 11 of the implant 1 with the implant shoulder 14 and the screwed-octa-secondary part 2 and its outstanding Octasegment 23. The manipulation implant 7 has the analog head 71 with the implant shoulder 74 and the projecting Octasegment 73, the form-locking of the connection part 32 fix impression cap. 3 To the threaded bore 24 in the octa-secondary part 2, a similar blind hole shaped Gewindeboh¬ tion is provided in the head 72 71st Through the passage 61 in the impression tray, the impression cap 6 and 3, a Positionier¬ is again screw 4 screwed to connect the analog 7 with the trapped in Abdrucklδffei 6 impression cap 3 firmly and without a gap. So 41 engages the threaded segment into the threaded bore 72nd To create the Meistermo¬ dells the negative mold obtained from the treated jaw line is then filled with a hard plaster and thereby the manipulation implant embedded. 7

While drawing which Toggle closing phases of work are no longer shown. After solidification of hard plaster, the positioning screw 4 is turned out and the negative form of the hard plaster mold - the master craftsman obtained model, which corresponds exactly to the contour concerned in the mouth of the patient -, separately. Thereafter, it applies a gold cap on the master model and on the protruding head 71 of the analog. 7 Finally, the restoration is waxed and gegosse and finally fired for the final prosthesis ceramic on the gold cap. The finished restoration, the patient is used, which is penetrated by a Titanokklusalschraube and engaged with the screwed into the implant 1 octa-secondary part 2, so that the restoration is now firmly seated on the implant. 1

This conventional system has in taking an impression on a number of disadvantages, particularly: • for fixing the impression cap 3 on the implant 1 both construction parts must screw 4 are interconnected by a Positionier¬;

• the impression tray 6 has to be provided with passages 61 which are to be placed just prior to taking an impression;

• from the passages 61 leaked excess impression material, ie the ge to the screw heads 42 formed Massepfropfen 51, 5 must be removed in order to be able to unscrew εchrauben 4, the positioning after curing of the impression material;

• only after the positioning screws are unscrewed 4, the impression tray can be removed 6 from the mouth of the patient and will be transferred to the dental laboratory;

• during l must begin 7 parts to the connection 32 of the impression caps 3 in the dental laboratory before the preparation of the master model and analogs with 4 Posi¬ tionierschrauben fix.

With the above connection arrangement, the creation of the master model is complicated as a whole, requires numerous operations and is tienten Pa¬ for the dentist as well as for the dental technician a laborious procedure.

From the US-PS 3,797,114 and 5,195,891 are releasable Verbin¬ extension arrangements known in the form of a plug-receptacle combination. The snap connections are thereby formed by a male member is inserted into a Aufnafimeelement, wherein the plug member has a pin with a ball-shaped head and the Aufnähmeelement has a ela¬ stisches gripping means. When introducing the element Steck¬ the gripping means is first widened; is fully implemented, the head of the male element, contractionary, the gripping means advantage again. The thus constituted snap connections consist of a plurality of relatively complicated items. It is particularly unsatisfactory that it has no reliable control over the adequate strength of the connection.

Finally, a further releasable connection arrangement with interlocking elements is known. Here, the receiving member has a slide animal under spring pressure Arre-, the ein¬ engages in a recess in the male member when the latter is inserted to the end position. That the connection can be released only with difficulty and the resilient locking slide is an element of uncertainty in terms of operational reliability, the disadvantages of this connection arrangement.

In view of the imperfections of the previously beschrie¬ surrounded the prior art, the invention has provided the Auf¬ administration to provide a much improved Verbindungsan- order. Here it is necessary to develop system elements which make it possible to simplify the impression taking and subsequent dental machining crucial. Furthermore, the Suprakon- are constructions for building, ie for intraoral attachment of artificial surfaces dental prostheses, as few elements may be required. The production and release of the connection is to be realized hung by simple linear relative movement and without additional Dre¬, otherwise the mechanism would again be complicated. It is believed that part of the connection assembly is fixed to the implant ver¬ prevented. The solution of this object is defined by the characterizing features of independent claim 1, while preferred embodiments of the dependent claims arise. The essence of the invention is that a plug anchor is provided with an elastic clamp head and a complementary contour, which together form a releasable plug-in connection. This contour - for example a latching shoulder - is arranged in the counterpart of the plug connection which is not fixedly connected to the plug anchor. This may, alternatively, the cap Abdruck¬ be the crown cap or no secondary part, said secondary part in the implant or in the Manipu¬ used lierimplantat or its integral part is. The plug anchor is either fixed pointing upwards in Sekun¬ därteil or pointing downwards fixedly disposed in the Impression or Kro¬ nenkappe. required to release the connector separation force is designed differentiated through targeted assessment of geometri¬ rule relations.

Figure 1

The inventive connection structure for the Abdruck¬ acquisition consists in principle of the inserted into the jaw bone implant 1 K, the screwed therein conical secondary part 8, which is screwed into the latter stud anchor 100 and the attachable to this impression cap 300th

in a conventional manner, the implant 1 has a conically widening implant head 11, which penetrates the mucous membrane S and the top side is flush with the implant shoulder fourteenth In the Implant head 11 is a downwardly conically narrowing bore - the implant cone 12 - see vorge. From the bottom of the implant cone 12 extends axially downwardly a blind hole-shaped threaded bore 13 into which screwed the threaded segment 82 of the conical secondary part 8 is. The conical secondary part 8 also consists of at the thread segment 82 subsequent Basisko¬ nus 81 and thereon upwardly tapered cone pillar 83. The base cone 81 is embedded in the implant cone 12 and includes with its upper edge substantially at the elevated internal shoulder of the implant shoulder 14 from, wäh¬ end protrudes out of the implant 1 83 of the conical pillar. From the top surface of the conical pillar 83 and therefore on the top surface of the entire conical secondary part 8 axially a blind hole-shaped threaded bore 8 extends downwardly.

In the threaded hole 84, the threaded segment 110 of the plug-in anchor is screwed 100th The plug anchor 100 is further from the send itself anschlies¬ to the thread segment 110 transitioning to an annular support shoulder 121 and the diameter of the extended shaft section 120 that protrudes from the cone pillar 83, the support shoulder 121 sitting on the cone abutment shoulder 85 auf¬. To the cylindrical shaft segment 120 closes overhang-like and abruptly expands the dome Kle m- Kopf 130, so that a clearly contoured, radially circumferential locking edge 131 results between the shank segment 120 and the clamping head 130th By the clamping head 130 vertically in the stem segment 120 to pull division slits 132, preferably two crosswise division slits 132, whereby four identical resilient in the horizontal plane armature laminations 133 are formed. The impression cap 300 has the typical angular se outer contour with ribs 303. cover on the underside of the Abdruck¬ 300 is the connection part 302 with the complementary to the implant shoulder 14 mating shoulder 301, wo¬ assured with a grout-free placing of the impression cap 300 onto the implant 1 is. Of the connection part 302 here, starting from the bottom of the impression cap 300, er¬ stretches axially and upwardly narrowing conical bore 304 in the inside of the impression cap 300. Ascending is the conical bore 304 in a cylinder bore 305 behind a on the inner wall expanded 306 provided radially circumferential locking shoulder 307 kavitätisch. The latching shoulder 307 is annular and downwardly formed conically narrowing, so that it axis occupies a rise angle α with the vertical, preferably 30 ° <α <60 °.

In the state plugged impression cap 300 of the cone to sit pier 83 in the conical bore 304 and the shaft segment 120 in the lower portion of the cylinder bore 305, while the clamping head 130 is above the locking shoulder 307, in the extended section of the cylinder bore 305th The elasticity of the fixed plug-in anchor 100 to the armature laminations 133 causes a pressure of the locking edge 131 to the latching shoulder 307, so that the impression cap 300 is moved almost in the vertical direction on the implant. 1 The mating shoulder 301 of the impression cap 300 is pressed onto the 'implant shoulder fourteenth To ensure this function, a minimum clearance between the Konus¬ must be respected drilling 304 and the outer contour of the cone pillar 83; the two cones may not otherwise be aufein-. The arrangement where the plug-in anchor is screwed into the conical secondary part 8 100 and the clamp head 130 protrudes will be referred to as an up position. will be discussed in the following explanations on the geometric conditions for ideal forces design.

Figure 2

Shown is a first design modification to the connection arrangement. The implant 1 having therein einge¬ screwed conical secondary part 8 and of the latter agree on ein¬ threaded stud anchor 100 with the previously bespro¬ rupted embodiment consistent. Only the clamping head 130 is designed flat; unchanged in principle, the outer contour of the impression coping 300. For receiving the Konus¬ are pillar 83 and of the stem segment 120 in the Ab¬ pressure cap 300 likewise the bore 305 provided an axial conical bore 304 and a directly subsequent Zylin¬. Instead of Figure 1 according to present latch shoulder 307 with the overlying extended portion of the cylinder bore 305 is here on the inner wall 306 and in the blind hole shaped cylinder bore 305, a radially circumferential, raised detent rib 308 exists.

The bore 305 has the clear Bohrungsdurchmes¬ ser d B, located in the region of the full amount of the latching web

308 ver¬ concentrated on the measure of the inside locking rib diameter R d, and the clamping head 130 has the Klemmkopfdurchmes- ser d κ. Consequently, we obtain the diameter ratios d B> d κ> d R. The locking rib 308 has the cross sectional shape of an isosceles trapezium, whose base is situated on the inner wall of the 306th The trapezium sides take the vertical axis here also the rise angle α one. Is the impression cap 300 inserted aufge¬ on the plug-in anchor 100, so there is the clamping head 130 above the locking rib 308 in the upper portion of the cylinder bore 305 and the locking edge 131 of the clamping head 130 pushes the upper trapezium sides of the locking ridge 308. In this way, the impression cap 300 again drawn in the vertical direction on the implant. 1 The mating shoulder 301 of the impression coping 300 is seated without joints on the implant shoulder 14; Impression cap 300 and the implant 1 are mutually fixed for the process of taking the impression.

When attaching or during removal of the impression coping 300 from the plug anchor 100 - the clamping head 130, the narrowing overcomes the locking rib 308 - need for compressed Ankerla¬ mellen 133 enough clearance to be present. The dividing slots 132 in the terminal head 130 must therefore have a ausrei¬ sponding slot width b have s. The partition slots 132 are provided in a slot length l s, which may er¬ stretch up to the vicinity of the threaded segment 110 of the plug-in anchor 100th

In order to produce the plug-in connection between the implant 1 and the impression cap 300, the insertion force is required F s; the impression cap 300 after the impression is taken - the impression material 5 must be sufficiently cured - deduct, one requires the separating force F τ. the aufzuwen¬

d κ, to the contour of the locking edge 131 and shoulder 307 and the locking ridge 308 and the resiliency of the armature laminations 133. At the elasticity of the armature laminations 133 have their material properties and geometry, including the Schlitz¬ width and length b s, l s , Influence.

Figure 3

As a different feature, the blind hole-shaped bore 305 in the impression cap 300 is provided in this constructional variant, without interruption, ie without a locking shoulder 307 and a snap-in web 308 to form. The fixation between the mounted impression coping 300 and the clamp head 130 of the plug-in anchor 100 is based here on the side acting against the inner wall 306 expanding force of the spring-loaded, compressed anchor laminate 133. In the state peeled impression cap 300 of the clamping head 130 is spread more. Is the impression cap 300 fitted, the friction effect at the Berührungs¬ area between the inner wall 306 and the Aussenwδlbung of the clamping head 130 retention of the impression coping 300 on the implant 1, that is, the connection part 302 of the impression coping 300 is seated fixed on the implant head 11 and the Gegen¬ shoulder 301 is therefore seamless to the implant shoulder on 14th A targeted surface roughness created on the clamping head 130 and on the inner wall 306 is conducive to the necessary solid, gap-free during the impression taking the seat of the mating shoulder 301 of the impression coping 300 on the shoulder Implantat¬ fourteenth

In a modification of the inner wall 306 just described completely unkonturiert, continuous, it is also feasible to make the cylinder bore 305 into two sections unterschiedli¬ chen diameter. Considering the Abdruck¬ cap 300 attached, it follows that, then a larger 120 to the conical bore 304, the bore 305 over a wide range of stem segment

Diameter than the upstream portion where the clamping head is positioned 130th The transition rule zwi¬ the lower, widened portion of the Zylinderboh¬ tion 305 and the upper, narrower portion forms a relatively narrow annular conical surface. When Auf¬ insert the impression cap 300 thus passes through the clamping head 130 first the extended portion of the cylinder bore 305. Upon passing the conical surface narrowing the armature laminations 133 of the clamping head 130 are quantitative presses progressively together. biased in this manner, the clamping head 130 then slides into the upper, narrower portion of the cylinder bore 305 and keeps the impression cap 300, as described above, due to friction.

Figure 4

This embodiment of the connection assembly is to figure 1 in that an extension, as placing an additional centering sleeve 9 in the implant head 11 which surrounds the reduced-large base of the cone 81 of the cone-secondary part 8 (see FIG. 5). Thus one achieves a GroES sere transmission accuracy in taking an impression with - \ 7 -

The conical secondary part 8. The alignment between the cones of the cone-pillar 83 and the conical bore 304 is more accurate. In order to obtain a certain elasticity the centering sleeve 9 has vertically arranged on the sleeve shell 91 expansion slots 92. Under the pressure of the screwed conical secondary part 8, the sleeve shell 91 snugly on to the implant cone 12, while centering the in their seated basal cone 81st In this embodiment, the conical pillar 83 has a lower-side, radially circumferential shoulder 86, is based directly on the implant shoulder fourteenth According narrowed the mating shoulder 301 of the impression coping 300 to make the shoulders 86 on the implant shoulder 14 place. The stud anchor 100 is designed in the manner described above.

Figure 5

the structure of the connection structure for the impression-taking using an angled conical secondary part is illustrated 8. This construction corresponds largely to the previously described Figure 4 with a axialsym¬ metric conical secondary part. 8 The now einge¬ sat angled conical secondary part 8 makes with the other structural parts to perform the impression-taking even with an inclination of the implant 1 in the range of 0 ° to 30 °. Accordingly, it is necessary to see vor¬ customized impression copings 300 the tilt angle of the conical secondary part. 8 The mating shoulder 301 of the impression coping 300 and the shoulder section 86 of the conical secondary part 8 are also located here on the implant shoulder fourteenth Advantageously, a centering sleeve 9 may also be provided in the implant head 11 of the implant unchanged. 1 The Impression cap 300 and the plug-in anchor 100 are identical to the previous embodiments in the rest formed. For fixing the conical secondary part 8 in the implant head 11 an insertable screw 87 is used, which is supported on an integrated seat in the conical secondary part 8 and engages the threaded bore 13 in the implant. 1

Figures 6a to 6c

From this figure result, three-phase structure of the joint assembly for taking impressions, for example a dental bridge structure is shown. According to FIG 6a are set enostal in the jawbone K bulky two mutually divergent ste¬ immediate implants. 1 Such a diverdie--saving implantation may be required by the specific Knochenange- offered. The implant heads 11 penetrate the mucosa while S and thus act as transmuko- sale units. screwed into the implants 1 are axisymmetrical conical secondary parts 8, holes in their Gewinde¬ 84, the plug-in anchor 100 now with their Gewindeseg- elements 110 are screwed. Figure 6b shows the so far prepared linkage arrangements with the positioned plug anchors 100 and the impression copings 300-to-install (construction according to Figure 1). After 6c completes the preparations for taking impressions. The Impression caps 300 are held by the clamping heads 130 and sit¬ zen with their counter shoulders 301 on the jointless tatschultern Implan¬ 14.

7 From this it is a more constructive modification of the connection structure for highly divergent seated implant did one out. The amendment refers to the Steck¬ anchor 100; otherwise the design of Figure 1 corresponds to that in the implant 1 is an axisymmetric conical secondary part 8 screwed. The centrally-drawn combination of implant 1, conical secondary part 8 and Steck¬ anchor 100 is intended to represent the ideal vertical position only for a clear comparison. is achieved, the adjustment to a strong inclination in that circumferentially on Steck¬ anchor 100 below the latching face 131, radially about the shaft segment 120, a recess is provided 122nd Is for the plug anchor 100, at least for the Klemm¬ head 130 and the subsequent shaft segment 120, a flexible material is - for example, a plastic material - used, one allows thus a skew compensating turning of the individual, resulting from the division of slots 132 of armature laminations 133rd the stability of the Klemm¬ connection between the clamp head 130 and the mounted impression cap 300 is not affected.

Figure 8

Shown is the use of the compound arrangement over the previously described impression taking is also continuous, now for attaching a superstructure, for example in the form of an artificial dental crown for a single-tooth Zk (individual may crown). The tooth crown Zk consists of internal, skeleton-forming crown cap 500 and the subsequent aufmodel¬ profiled tooth Za. In principle, the crown cap 500 has the impression copings 300 in accordance with the previous figures (except Figure 3) identical inner contour. The gur 3 based solely on friction to financial clamp connection zwi¬ rule the clamping head 130 and the impression cap 300 is for fixing a tooth crown Zk, because of this notwen¬ ended firmer seat, out of the question.

Is present, the implant 1 with the implant head 11, the implant cone 12, the downwardly er¬ from this space stretching threaded bore 13 and the top of radially encircling implant shoulder 14. In the implant 1, a conical secondary part 8 is used, whose construction and screw connection the implant 1 has already been described ben. The cone pillar 83 extends, as previously already explained, from the implant head 11 out. In the Gewin¬ debohrung 84 of the conical pillar 83 in turn is a Steck¬ screwed anchor 100 with its threaded segment 110th In the manner outlined above, the shank segment 120 and the clamping head are designed 130th The crown cap 500 has a connection part 502 at the bottom located to the mating shoulder 501, which rests on the implant shoulder jointless fourteenth Analogous to the impression cap 300 is a conical hole 504 of the connection part 502 extends axially upward in the crown cap 500 into the conical bore 504 passes into the blind hole bore 505, and on the inner wall 506 is of the snap-in web 508 see vorge.

When attaching the tooth crown Zk just before the Kronenkap¬ pe 500 jointless sitting on the implant 1, the locking web jumps 508 via the clamping head 130 and the locking edge 131 now presses on the locking rib 508, whereby the tooth crown Zk is drawn onto the implant. 1 The tooth crown Zk has much safer and firmer aufge¬ on the implant 1 puts his than is required when taking an impression. The expended for fixing a superstructure for releasing the connection assembly separating force F τ 'must be sized considerably higher than with a impression taking. To achieve this, various individual measures or a combination thereof are possible. in relation to the impression taking - - reduced most practical it is a

Locking rib diameter d R 'provide, after which d R> d R' is obtained. Also, the rise angle α could be enlarged, so that the relevant for holding upper ordered approaches pezschenkel the locking web 508 more to the horizontal, and thus represents a major obstacle for the locking edge 131 in the intentional or unintentional removal of the tooth crown Zk. This arrangement can Verbindungs¬ likewise be used for the attachment of artificial surfaces individual teeth or bridge constructions.

Especially advantageous for the single-tooth replacement is the initial execution of the connection arrangement with rotational securing, which will be explained first for taking an impression. Instead of the previously used conical secondary part 8 is a octa-secondary part 2 will now be screwed into the implant 1, as it has already been through Oc-shown in the diagram of the prior art with reference to FIGS Oa. The base 21 of the cone-octa secondary part 2 is seated in the implant cone 12, and the threaded segment 22 of the octa-secondary part 2 engages in the threaded bore 13 of the implant. 1 The whole Octa¬ segment 23 protrudes beyond the implant shoulder 14. Due to tolerances and different screw of octa- secondary section 2 and the horizontal ledge 25 between the cone base 21 and the Octasegment 23 can rise over the implant shoulder fourteenth

Again 100 is screwed with its threaded segment 110 in the presence of the secondary part 2 octa-threaded bore 24, a plug anchor. The faceted the threaded segment 110 of the shaft segment 120 and on top arranged clamping head 130 extend freely without the plugged impression cap 300 in the height. The shaft segment 120 which sits upon delimiting below support shoulder 121 on the Octaschulter 26th In relation to the impression copings 300 in Figures 1 or 2, the impression cap 300 is now used has externally the same texture. In plugged position the impression cap 300 sits with its mating shoulder 301 without joints 14 on the implant shoulder However, the inner contour of the connection part 302 of the impression cap 300 is shaped complementarily to the Octasegment 23 and has dem¬ on by an inner octagonal 27th In the event that the ledge 25 extends beyond the implant shoulder 14, a radially encircling recess 309 is provided on the inner edge of the counter-shoulder three hundred and first Thus, the mating shoulder 301 put under increased Sims 25 ter seamlessly to the Implantatschul¬ 14th

The internal octagon 27 is axially ascending as sack¬ hole-shaped bore 305 continues into which the shank segment 120 and the clamping head extending 130th As already described for the preceding figures, is provided on the inner wall 306 is a raised, radial locking web 308th In the assembled state is then seated, the upper trapezium sides of the locking rib 308 of the locking edge 131 of the clamping head 130. Instead of the detent rib 308 could also have a locking shoulder 307 (see FIG. 1) on the inner wall 306 to be incorporated or the inner wall 306 is continuous designed ( see FIG. 3). With the Ein¬ set an octa-secondary part 2 in the connection arrangement twisting the mounted, adjusted Abdruck¬ is cap 300 excluded.

Figure IQ

the connection assembly is illustrated with a dung Verwen¬ octa-secondary part 2 during the impression taking, wherein, finally, is provided with transversal screw attachment of a superstructure. In the con- according constructive tion 9 screwed to the thread segment

110 of the plug-in anchor 100 directly into the threaded bore 24 of the octa-secondary part 2. Now, however, is also inserted a required for the recorded below Transversal screw bolt 200th The screw bolt 200 has a threaded segment 210 which is threaded into the threaded bore 24 of the octa-secondary part. 2 To the thread segment 210 is a sleeve segment 220 adjoins having an axially of upwardly extending, blind-hole-shaped threaded bore 221 for receiving the overall indesegments 110 of the plug-in anchor 100th On foreign extensive the sleeve segment 220 has a radial groove 222nd

This bolt 200 can be screwed even before the Abdruck¬ takeover. but then you need a special impression cap 300 with an extended cavity 310 to create 200 room for the bolt. It is also possible, taking impressions with the connection arrangement according to FIG 9 - without the Schrauben¬ bolts 200 - make and to use this only after removal of the plug-in anchor 100, advertising in preparing the Transversalverschrau- (see Figure 11).

Figure 11

Shown are the dental technician serving as a scaffold for the construction of a superstructure crown cap 500 is versalverschraubung with transport, preferably in the form of a gold cap. The superstructure, for example a dental crown, is applied to the crown cap 500 prior to insertion into the bite of the patient. Present is an implant 1 which is equipped with a secondary part octa-2, whose Octasegment 23 projecting above the implant shoulder fourteenth The Octasegment 23 and the screwed bolts 200 are received by the crown cap 500th The latter has a connection part 502, the mating shoulder 501 rests on the implant shoulder jointless fourteenth At the inner edge of the mating shoulder 501, a radially encircling recess 509 is provided. If the ledge 25 of the octa-secondary part 2 extend above the implant shoulder 14, thus the toast to the opposite shoulder 501 is avoided.

Of the recess 509, a 24-inner edge 403 extends vertically into the crown cap 500, which receives the Octasegment 23rd By combining 24-inner edge 503 and Octasegment 23 will be apparent to the-set-up Kronen¬ cap 500 a total of 24 possible slot positions in each case 15 ° increments. At the same time the abutting edges of the 24-Kant inner 503 and the Octasegments 23 serve as a guide for the crown cap 500. Further upward is the 24-inner edge 503 in a sacklochför strength cylinder bore 505 to accommodate the sleeve segment 220th

The side having the crown cap 500 a compact Mate¬ rialschenkel 510 with a pointing downwards, integrated and directed toward the radial groove 222 threaded bore 515. This tapped hole 515 lies sunk a pin screw 516 whose rounded tip 513 tangential to the upper edge boundary of the radial groove 222 scored and thus causes the pressurization of the crown cap 500 on the implant shoulder fourteenth By means of the stud bolt 516 is fixed to the crown cap 500th For setting a Eindrehwerkzeuges be¬ the stud 516 sits a head slot 514th

Figure 12

Starting with this figure now follow embodiments of the joint assembly in the down position. Windwärts position in the emergence of the plug armature 100 segment with its thread 110 in a octa-secondary section 2 or in a conical secondary part respectively screwed 8 and the clamp head 130 upward, while the aufzusteckende Abdruck¬ or crown cap 300, 500 of the clamping head 130 in itself auf¬ takes. The characteristic of the down position, however, is that an inversion is provided by the fact as now the downward push anchor 100 permanently in the Impression or crown cap 300, sits 500 and for producing the clamped connection in a special, acquisition to Auf¬ of the clamping head 130 designed conical secondary part 8 is inserted. The connection structure for taking impressions is initially also on the existing implant 1 with the implant head 11, the implant cone 12, the threaded bore 13 and the shoulder 14 of the implant. Axial is screwed into the implant 1, a conical secondary part 8 whose thread segment 82 engages in the threaded bore 13 and the base of cone 81 is seated in the implant cone 12th Over the implant shoulder 14, the conical pillar 83, which closes up with the annular and radially encircling cone abutment shoulder 85 protrudes. From the top of the cone pillar 83 and therefore on the upper side of the entire conical secondary part 8, a blind hole-shaped bore 805 extending axially in the interior of which serves to receive the plug-in anchor 100th In the current example 806, the inner wall of a raised locking rib 808, which has the same function and shape as the locking web 308 of Figure 2. It is also possible, instead of the Rast¬ web 808, one for locking shoulder 307 (see Figure 1) provide identical contour or shape throughout the interior wall 806 (see Figure 3).

The mass ratios within the cylinder bore 805 are adequate to the conditions in the impression cap 300 (see Figure 2) designed. The bore 805 has the clear bore diameter d B, which is in the range of

Detent ridge 808 on the narrowed locking rib diameter d R. The trapezoidal leg on locking web 808 take here with the vertical axis the slope angle α one. Indiscriminately, the outer contours of the impression copings 300, regardless of whether it is stepping forward to the variant of Auf¬ or acts downward position different, however, the internal configurations. The impression cap 300 for the down position at first also has a connection part 302 with the mating shoulder 301 in an identical manner, and an upwardly narrowing conical bore 304 with the diameter dg summit to absorb the entire cone pillar 83rd

To the tapered bore 304 to a closer and relatively flat cylinder bore 311 adjoins, narrows again from the off, a blind hole-shaped threaded bore 312 extends axially in ascending order. The cylinder bore 311 forms a form-fit seat for the partially located therein, cylindrical support segment 140 of the plug-in anchor 100. The support segment 140 forms an intermediate member; on its upper side is where the ascending thread segment 110, while the downwardly facing shaft segment extends from the bottom 120, is integrally formed on the clamping head at the bottom of the 130th Into the threaded bore 312, the threaded segment 110 of the plug-in anchor 100 engages, so that it is tightly connected to the impression cap 300th In turn, the clamping head 130 has the latching edge 131, Tei¬ lung slots 132 with the slit width b s and length L s and Schlitz¬ formed thereby armature laminations 133 as well as the geometric dimension of the clamping head diameter d κ. The Durch¬ diameter ratios resulting characterized by d R <d κ <d B <UQ. In the state plugged impression coping 300 is seated the conical pillar 83 in the conical bore 304 which Konuspfeilerschul¬ ter 85 is located near the bottom of the conical bore 304 and the support segment 140 has the bore 805 partially inserted into the cylinder. Into the cylinder bore 805 into the shaft segment 120 also extend to the clamping head 130. The clamping head 130 has overcome the narrowing locking ridge 808, so that the locking edge 131 now engages under the lower legs of the trapezoid catch web 808th However, since this is fixed, the elastic laminate 133 Anker¬ strive to repel from the locking rib 808 and thus pull the impression cap 300 connected to the plug anchor 100 downward. As a result, the Ab¬ is pressure cap 300 is pressed onto the implant 1 and the counter-shoulder 301 sitting without joints on the implant shoulder 14. For the making of the plug connection, the plug-in force

F s is required; If one wishes to disconnect, the separating force F τ is to be applied.

Figure 13

The changes compared to the previous figure refer to a modified conical secondary part 8, the width of the-engaging to the implant shoulder 14 mating shoulder 301, as well as the fixing of the plug-in anchor 100 in the impression coping 300. The threaded segment 110 of the plug-in anchor 100 and the impression coping in the 300 intended for screwing threaded bore 312 will now be through a plug pin 150 on the plug anchor 100, and a, a press fit forming Zylinder¬ bore 322 in the impression cap 300 is replaced. The relieving hole in the ZY 322 inserted plug pin 150 is ten gehal¬ by the clamping action of the press fit into the impression cap 300th

The cone pillar 83 of the conical secondary part 8 here also has the lower-side, radially encircling Schulterpar¬ tie 86 is based directly on the implant shoulder fourteenth The mating shoulder 301 of the impression coping 300 is reduced in width, so that the shoulder section 86 can be based on the implant shoulder 14 (see Figure 4). Further, on the conical pillar 83 an externally circumferential radial groove 809 is provided which serves only the later Transversalverschrau¬ bung. At the upper end of the basal cone 81 - unmit¬ telbar under the approach of the conical pillar 83 and still surrounded by the implant head 11 - is a further radial groove 810 incorporated. This radial groove 810 serves to receive a clamping ring 900, wherein the function of centering of the conical secondary part 8 - has - similar to the centering sleeve 9 (see Figure 4). In addition, the clamping ring 900 also acts as a rotation lock; unscrewing of the conical secondary part 8 from the implant 1 is made more difficult. Instead of the clamping ring 900 and the centering sleeve 9 would be used as long as it reduces the contour of the cone base 81 accordingly.

Figure 14

This embodiment of the connecting assembly for acquisition Abdruck¬ is compared with the previous variant inasmuch an extension is, as the cylinder bore in the pillar cone of the conical secondary part 8 is partially provided with an internal thread 811 805 83rd The internal thread 811 er¬ extends from the locking rib 808 upwardly to the level of a downwardly extending from the conical abutment shoulder 85 cylindrical counterbore 812. Opposite the cylinder bore 805, the counterbore 812 is increased, inserted into which einge- partially in zusam¬ quantitative inserted state, the support segment 140 is , As the radial groove 809 is also the Innenge¬ thread 811 for taking an impression at first without function. Only for the transverse or occlusal screwing the auf¬ on the stocked with the conical secondary part 8 implant 1 set superstructure the radial groove 809 or the internal thread 811 is used by a screw. The Gewinde¬ peaks of the female thread 811 are flattened so that the armature laminations 133 of the clamping head 130, and in a view Hin¬ also the internal thread 811 itself, during insertion or extraction of the plug-in anchor 100 are protected.

Figure 15

Presented is a constructive modification of Verbin¬-making arrangement for the purpose of taking an impression of extreme diver¬ gent implants placed first Opposite the Vorgängerva- riante are receiving the plug-in anchor 100 in the Ab¬ pressure cap 300 and the plug-in anchor 100 itself is changed, the here laterally deflected is mounted. The conical bore 304 and / or the conical pillar 83 of the conical secondary part 8 must be such that in the state plugged impression cap 300 between the inner wall 306 and the

Cone pillar 83, a gap for the operation of withdrawing the impression cap 300 is present. From the top surface of the Ab¬ pressure cap 300 extends an axial threaded hole 330, which continues as a cylindrical bore 332 to a comparable narrow ends acetabulum 333rd Of the socket 333 to the conical bore 304 extends a cylindrical Durch¬ break bore 334th

The plug anchor 100 has the clamp head 130, the adjoining shank segment 120 and - now used - one on the other on the shaft segment 120, the clamping head 130 diametrically opposed, arranged ball joint 160. The ball joint 160 is located in the cylinder bore 332 and is measured by an over the joint ball 160 also disposed in the cylinder bore 332 spacer segment 340 held without play on the joint socket 333rd On which the ball joint 160 side facing the spacer segment 340 has a tapered countersink 341. From a screwed into the threaded hole 330 screw 350 receives the spacer segment 340 has a certain amount of pressure in the direction of the ball joint 160. The shaft segment 120 penetrates the greater breakdown bore 334, so that a structurally be¬ bordered, lateral deflection of the plug-in anchor is possible 100th The spacer segment 340 and the screw 350 are preferably made of plastic.

To the plug 100 with the anchor directly for the next to the shaft segment 120 ball joint 160 a modified alternative solution is possible. Using a plug-in anchor 100 with an adjoining the shaft segment 120 thread segment 110 (see Figure 1), 'which steering ball in a Ge 160 which sits a complementary threaded bore be¬, is screwed. The connection arrangement according to Figure 15, instead of used for centering in the radial groove 810 clamping ring 900 with the centering sleeve 9 (see Figure 4) to be equipped. The function of this particular Verbin¬ describes dung arrangement. Suppose taking an impression of the jaw with two highly divergent implants placed 1 must be performed. First, you put each Abdruck¬ a cap 300 with the plug laterally deflectable armature 100 to the implants 1. The terminal heads 130 slide under the locking sleeves 808, whereby the impression copings 300 are fixed on the implants 1; the counter shoulders 302 sit without joints on the implant shoulders 14. According to the divergence of the implants 1 used the impression copings 300 are positioned divergent to each other. If you hold the impression compound with 5-filled impression tray 6 on the jaw, wherein the mutually inclined impression copings 300 are aligned so embedded in the impression compound 5 (see FIG. Oa). After curing of the impression material 5 of the impression tray 6 is lifted. During takeoff, the shaft segments 120 and clamp heads 130 of the drive stud anchor 100 from the cylinder bores 805, the first demand the clamping heads 130 have overcome the detent webs 808th With continued raising of the impression tray 6, the movable plug anchor 100 undergo a deflection to compensate for the divergent starting position.

Figure 16

Shown the connector assembly is in the down position after the impression is taken (see FIG. Oc). The impression cap 300 is embedded in the impression tray 6 with the hardened impression material 5 and the analog 7, which has an analogous to the implant head 1 outside geometry, has already been put together with the impression coping 300th In this way, the situation at the respective jaw line, as an imprint from a negative image with the original implant 1 replaced Manipulier¬ implant 7 has been obtained. There now follows the production of the master model. Also during this phase, the inventive connection arrangement is aimed ver¬ beneficial.

The impression cap 300 has the axially and downwardly positioned stud anchor 100 in its interior. On the head 71 of the manipulation implant 7 is a plug-in receptacle 700 is set auf¬. Preferably, the manipulation implant 7 and the plug receptacle 700 are integrally designed. Thus ent the outer contour of the analog 7 responds with the plug receptacle 700 of the combination of the implant 1 and

Secondary part - here the eighth conical secondary part analog to acting as counterpart to the connection arrangement conical secondary part 8 is the plug-in receptacle 700 designed (see Figure 12).. Thus 700 has the plug-in receptacle for a komple¬ existing in the impression cap 300 conical bore 304 mentary cone pillar 783 which passes outwardly through the Implan¬ tatschulter 774 for manipulation. 7 Ober¬ side closes the plug receptacle 700 from the Konus¬ pillar shoulder 785th Further, the plug receptacle 700 has an axially and vertically extending sackloch¬ shaped bore 705 with the inner wall 706 to which the raised detent rib 708 rotates radially.

In the assembled state, the mating shoulder 301 of the impression coping 300 is seated on the implant shoulder jointless

774. The cone pillar 783 of plug receptacle 700 is pushed into the ein¬ located in the impression cap 300 conical bore 304 so that the conical abutment shoulder is close to the overhead due to the conical bore 304 785th relieving hole in the Zy¬ 705, the support segment 140 of the plug-in anchor 100 entirely and the shank segment 120 and clamping head 130 are partially inserted. The clamping head 130 passes over when connecting manipulation implant 7 and the impression cap 300 the snap-in web 708 is pressed together and expands behind the locking web 708 again, so that the locking edge 131 is locked under the locking web 708th In connector assemblies in a downward position can be divided advantageously for attachment to octa- and secondary cone-2, 8 provide an internal thread 811th For the Steck¬ 700 shots at manipulation implants 7, however, is a cylinder bore 705 sufficient. Also, it is sufficient to measure the geometrical relationships in such a way that the sufficient for taking impressions insertion force F s or Trenn¬

τ force F ceases. After casting the master model, using the existing impression from the infected manipulation 7 Steckver¬ can bond be solved implant 7 easily again between the impression cap 300 and the Manipulier¬. The master model thus obtained serves as a positive image of the original situation from the mouth of the patient's successor constricting creation of the superstructure.

The following Figures 17 to 20 show various Windwärts position, previously described embodiments of the connection assembly in Ab¬ which will now be used to attach a single crown Zk. Figure 17

This embodiment provides a structural conversion to Ver¬ binding assembly of Figure 8 with use of serving as a plug-in receptacle conical secondary part 8 of Figure 12 illustrates Accordingly, there is the arrangement of Figure 17 from the implant 1, formed the conical secondary part 8 with a plug-in receptacle. cone pillar 83 and a crown cap 500. in the same manner as in the impression cap 300 according to Figure 12 of the plug-in anchor is configured 100 and arranged in the interior of the crown cap 500th

Since it is the attachment of a tooth crown Zk, it will ensure that the force required to peel off the tooth crown Zk separation force F τ 'is much larger dimensioned than the separating force F τ when taking an impression. In hie¬ sigen example, the increased separating force F τ 'is thereby provided ein¬ by the detent web diameter to the value of d R' narrowed. This means you need would take and different for the crown mounting conical secondary parts 8. An alternative way to provide dif¬ ferentiated release forces F τ and F τ 'for both tasks, is to use different plug anchor 100 for the media publication, ie geometry or material properties shadow to change.

If one puts the tooth crown Zk to the implant 1, the connection part 502 drives the crown cap 500 through the pillar-Konus¬ 83 to the opposite shoulder 501 sitting on the implant shoulder jointless fourteenth Synchronous drives through the Klemm¬ head 130, the cylinder bore 805 and bounces finally under the catch web 808. For this one must 'apply the insertion force F s. It is easier to implement, and nothing speaks against it at an increased separation force F τ 'an increased insertion force F s' set. If the Steckver¬ connection between tooth crown Zk and implant one to solve, for example, for a cleaning, it is necessary to clamp head 130 under

Pull expenditure of greater separation force F τ 'over the obstacle of the locking ridge 808th

Figure 18 r

For this connection assembly, also a Konstruk¬ tion, for example for the attachment of an individual tooth crown Zk, a conical secondary part are 8 as shown in FIG 13 as well as a crown cap 500 with Transversal, in abgewan¬-punched to form 11 is used. In the implant 1, a conical secondary part 8 is inserted, which has a bearing on the implant shoulder 14 shoulder portion 86, a radial groove 810 in the base cone 81 for receiving a Klemm¬ ring 900 and a radial groove 809 to approach the tip 513 of a stud 516 for the transverse has screw connection. The tooth crown Zk consists of ge rüstbildenden crown cap 500 environment with the Transversalverschrau-, the crown cap 500 largely be covered

Gold cast and Go latter abdeckendem porcelain coating Po.

The directed with its clamp head 130 downward plug anchor 100 sits with the holding plug pin 150 in the acting as a press-fit bore 522, and that adjoining the plug pin 150 support segment 140 is located with its upper part in which are coaxial and below to the cylinder bore 522 subsequent cylinder bore 511. from the support segment 140 extends down the Schaftseg¬ element 120 with the lowermost arranged clamping head 130. the crown cap 500 itself consists of the cap housing with which 511 coaxially anschliessen¬ to the cylinder bore to the extended by the latter starting and downward to opening tapered bore 504. Laterally, the crown cap 500 includes a compact, thickened material legs 510, in which a downwardly facing, integrated and directed toward the pillar provided in the cone 83 radial groove 809 Gewin¬ debohrung 515 is present. In the threaded bore 515, a stud 516 is positioned, the rounded tip 513 encounters tangential to the upper edge boundary of the radial groove 809 to repel it and thus causes the pressurization of the crown cap 500 on the implant shoulder fourteenth With a screwing tool can engage the head slot 514 of the stud 516 for adjustment.

If the tooth crown Zk attached to the implant 1 and the Transversal occurs, one has achieved an additional secure fixing of the tooth crown Zk on the implant. 1 When attaching the tooth crown Zk the snap connection between the clamp head 130 and the cone pillar 83 first comes into existence; the locking edge 131 has jumped under the catch web 808th Is then screw 516, the Stift¬ extent screwed into the threaded bore 515, the tip 513 of the stud 516 penetrates in the radial groove 809 and abuts against the upper edge of the radial groove 809 which takes the effect of guaranteeing the Transversalver¬ a screw connection. Through the lateral collision of stud bolt 516 and conical pillar 83, the entire crown cap 500 is pressed with the applied tooth crown Zk in the direction of the implant. 1 The mating shoulder 501 sits seamlessly on the implant shoulder 14th

The crown cap 500 with its conical bore 504 receives its guidance on the conical outer contour of the conical pillar 83. A centering of the entire connection assembly further cause the clamping ring 900 and the form-fitting seated on the one hand in the cylinder bore 511, and other hand held in the cylinder bore 805 support segment 140. A et¬ waigen tilting of the crown cap 500, caused by the force of the stud bolt 516 is opposed the support segment 140th The precise centering of the scaffold-forming crown cap 500 and the nen of this getrage¬ tooth crown Zk can thus by the Transversalverschrau¬ environment are not compromised. Is it necessary to remove the tooth crown Zk, you must first pin the screw 516 and to bring the snap under Auf¬ 'solve the separation force F τ. However, given the zusätz¬ security interest by the Transversal here it is not mandatory to make the previously described steps to have the opposite F τ increased Trenn¬

force F τ set '.

Figure 19

In contrast to FIG 18 - otherwise agree, the construc- tions in total agreement - will find here a standard contemporary crown cap 500 without the additional Transversal¬ gland use and inside the cone pillar 83 the locking web 808 is mounted in front, an internal thread 811 attached (see figure. 14). The fixing of the tooth crown Zk on the implant 1 is now effected in the interior of the conical secondary part 8 only by the Steckverbin¬ connection between the plug anchor 100 and the locking web 808th The radial groove 809 and the internal thread 811 currently have no tion Funk¬, ie, they are not used in the current example. Given the increased load on the connector in mounting a dental crown Zk - against a weni¬ ger loaded impression cap 300 - must be increased

Setting the release force F τ '. The purpose in question

Opportunities have already been explained. Particularly lends itself to a stud anchor 100 with - in relation to Ab¬ pressure measure - enlarged clamping head 130 for use. Since the plug-in anchor 100 are firmly connected to the copings 500 in a press fit between the male pin 150 and the cylinder bore 522, any risk of confusion is excluded.

Figure 20

The dental crown occlusal Zk is screwed with the eingesetz¬ in the implant 1 th conical secondary part 8; the male anchor 100 is now completely unnecessary. In addition, here one needs a occlusal screw 400, in the form of a head screw, so¬ as an access hole to by the aufmodellierten teeth Za the crown cap 500 and a counterbore 530 on the upper side of the crown cap 500 is used, in turn, a standard according crown cap 500, with was built the applied gold cast Go and porcelain coating Po to crown Zk. Of the occlusal surface of the tooth crown Zk forth the vertical access to bore extends through all of the ten Schich¬ aufmodellierten to the crown cap 500 tooth Za therethrough. This access bore to be for introducing and also for any necessary removal of the

Occlusal 400 needed from the tooth crown Zk. If the gland produced, closes to the Zugangsboh¬ tion to a corresponding mass.

The envisaged on the top of the crown cap 500 An¬ reduction 530 is used to hold and as a seat for the head

420 of the occlusal screw 400. The threaded segment 410 of the occlusal screw 400 penetrates the cylinder bore located in the ceiling of the overcap 500 crown 522 and engages the internal thread 811, which for this purpose in

is provided cone pillar 83, a. For application of a screwing tool 420 has the head of an engagement contour
