Description

"Set of components for the detachable connection of dental prostheses

with the adjacent tooth crown or crowns11 The invention relates to a component set for the detachable connection of dentures with the or the neighboring tooth crowns via attachments according to the telescope principle.

Attachments, which according to work the telescope principle, known different types. The main ones are grooved shoulder-pin attachments, rod attachments with T-shaped bars or cylindrical ones Roller as well as anchor attachments, with the groups of the last three attachments also below the term patent attachments are summarized.

With grooved shoulder-pin attachments, one works either with telescopic ones Full or partial crowns, the outer crown with the removable denture is connected, while the inner crown is on the as an end pillar for the denture serving tooth is permanently applied. The inner crown of the end pillar Part of a crown also of the teeth adjacent to this end pillar be to the forces to be transmitted from the prosthesis to the remaining teeth cheaper to distribute.

Each of the patent attachments mentioned has an attachment matrix and a male attachment is provided which cooperate telescopically, wherein usually the attachment matrix with the crown of the tooth serving as a pillar of the prosthesis wearer is firmly connected, while the attachment patrix with the load-bearing Part of the dental prosthesis, i.e. the model casting, must be connected in such a way that the required Power transmission from the removable dental prosthesis or the prosthetic part the cornerstone or crown of the neighboring teeth of the denture wearer is guaranteed.

With all attachments, the parts of which are all made of metal, the required holding force of the interacting telescoping parts is achieved Corresponding friction is guaranteed, with the holding or clamping force as a rule due to the resilient design of the attachment part connected to the removable dental prosthesis he follows. This provides the required when the holding or clamping force is released Reactivation simplified.

A particular problem with all attachments is that the cooperating attachment parts not only with a very good fit to the Corner pillars on the one hand and the removable one Prosthetic part on the other hand must be attached, but with the usually necessary arrangement of several Attachment for the removable attachment of the dentures is extraordinary exact parallelism of all interacting surfaces of the telescoping parts mandatory requirement, otherwise the insertion and removal of the dental prosthesis becomes impossible or at least additional loads are exerted on the remaining dentition which are associated with very detrimental consequences.

The processing and processing of the component sets for the various Attachment types known fasteners is with an extraordinarily large Costs associated with the dental laboratories, with particular difficulties result in that one of the attachment parts are connected to the model casting got to. So far, only one soldered connection is known, which, however, is a large one Requires time and money, apart from the fact that the subsequent Warming up of the model casting in the area of the soldering point and the different thermal expansion of the parts to be connected with one another the necessary precision and accuracy of fit can not be adhered to and also a thermal post-treatment of the soldering point is required.

The aforementioned difficulties also arise when due to fatigue or damage to the reactivatable part of the attachment due to other circumstances occur which according to the above, usually at the removable denture is arranged. The replacement of such a defective attachment part requires almost the same effort as the completely new production of the corresponding Dental prosthesis, as all plastic parts must be removed in order the soldered connection between the cast model and the attachment part to be connected to it to be able to manufacture.

Finally, there is a further complication that the different Attachments also require very different working methods and instructions.

A set of components is known (magazine "Das Dentallabor" Issue 5/83 page 652) which has a cast-on attachment matrix for a double-T attachment and an attachment male equipped with a retaining ring, which is used for A fastening screw is used and a threaded cap is provided is in which the ring connected to the patrix and the fastening screw intervene, but with this solution the threaded ring must also be cast with the model be connected by soldering. A soldered connection is avoided in this design between the attachment patrix and the cast model, however, the soldered connection must be used for this between the threaded cap and the model casting accept which of the above Difficulties in terms of workload and compliance with the required Accuracy of fit leads. In the known design, the male part can be exchanged will, however, this solution requires a force-transmitting part a slotted ring which is connected to the threaded cap to be soldered or forms part of the threaded cap.

The invention is based on the object of providing a component set of the initially called type so that each soldered connection between the attachment parts and the model casting is omitted and a detachable one for all attachments mentioned in the introduction Connection of the attachment part held on the removable denture with only a few identical or similar parts is possible.

A first embodiment is used to solve the above problem of the component set by a) a die part made of cast-on platinum / iridium, which forms a cylindrical fitting ring, or from a cylindrical fitting ring made of platinum / iridium consists in a casing made of residue-free combustible plastic, b) a Male part, also made of cast-on platinum / iridium with one in the fitting ring of the die part insertable hollow cylindrical section with internal thread, to which a radially outwardly projecting shoulder and an axially upstanding shoulder Connect sprue section, c) one that can be screwed into the internal thread of the male part Retaining screw or an anchor attachment pin equipped with a stepped thread section, d) a duplicating aid with an embedding section and a further section, which is the contour of the section that can be pushed into the fitting ring of the die part of the male part, e) the embedding section of the auxiliary duplicating part Corresponding cap part for plugging onto the sprue section of the male part and f) a fixing screw that can be screwed into the internal thread of the male part.

The mentioned female and male parts are in the aforementioned Execution not the attachment matrices and attachment matrices, although they do can also be in another embodiment variant mentioned later.

The mentioned female and male parts are in the case of the one described above Set of components that can be cast on, one of which is attached to the model casting and the other to the crown of the tooth or pillar adjacent to the removable dental prosthesis is cast on. As a rule, the die part is cast onto the Crown of the abutment tooth and the casting of the male part onto the cast model. For example becomes the die part when using the component set for conical or telescopic crowns appropriate to the outer crown or outer partial crown, e.g. for grooved shoulder-pin attachments, molded and the male part to the model casting, with the help of Fastening screw the male part, which is connected to the outer crown by casting, is detachable in the female part is held and thus the releasable attachment of the dental prosthesis on the pillars is ensured by the interaction of the inner and outer crowns.

According to the above statements, the matrix part can consist of a total of one There are cast-on platinum / iridium and form a cylindrical fitting ring, or but it can be designed so that a cylindrical fitting ring made of platinum / iridium Is held in a casing made of residue-free combustible plastic. At the The last-mentioned form of the die part is cast onto the plastic replaced by the cast-on metal, so that the cylindrical fitting ring with the cast-on Part forms a unit. The formation of the die part in the form of a cylindrical Fitting ring with a casing made of residue-free combustible plastic usually given preference because of the cost compared to such a die part the massive formation of cast-on platinum / iridium are significantly lower and any necessary machining of the die part easier when modeling are to be carried out, as these machining operations are carried out in the case of a plastic sheathing of a cylindrical fitting ring only need to be made on the plastic.

If the female and male part together with the said Anchor attachment pin are used, it is recommended that the die part is stationary on the pillar The held crown to be cast on and the male part to be cast onto the model casting again In this case, however, it is useful to have an additional one to accommodate the anchor attachment pin Anchoring matrix part made of platinum / iridium to be provided, which in its inner and outer contour corresponds to the female part for receiving the male part, but a double-conical one Has course of the inner wall surface and the two mentioned die parts with corresponding projections and depressions to form a plug connection equip.

The additional die part should be made of materials which there is to be adapted to the female part, which is to receive the male part serves. It is useful if with a die part with a fitting ring Platinum / iridium in a coating made of residue-free combustible plastic that additional anchor matrix part also a ring part made of platinum / iridium in one Has sheath made of residue-free combustible plastic, and if the sheaths of the two die parts dowel pins and corresponding holes or slots have to produce the said plug connection of these parts before they are molded will.

The additional die part is used to hold the anchor pin, which is in turn connected to the male part by a screw connection. at The anchor attachment is practical for this design and application of the component set integrated into the interacting female and male parts of the component set.

The cylindrical fitting rings of said die parts are in the Usually designed as circular cylindrical fitting rings, albeit one other annular cross-sectional shape is possible. Because of the very high necessary Accuracy of fit as well as for cost reasons is the circular cross-section the fitting rings and the male parts that can be inserted therein are preferred.

By equipping the male part with a radially outward protruding shoulder following the hollow cylindrical threaded section a safe and reproducible support of the male part on the female part when using a locking screw in the screwed together state of the two Parts guaranteed. When using an anchor attachment pin screwed into the male part becomes a through the radially outwardly projecting shoulder of the male part safe and also reproducible contact of the male part on the female part ensured in the connection position of the dental prosthesis with the adjacent pillars.

With the help of the above-mentioned duplicating aid and the cap part, which corresponds to the embedding section of the duplicating aid is a safe one and extremely precise fixation of the male part in the model casting Guaranteed shape to be produced. The fixing screw that can be screwed into the male part serves to protect the thread of the male part up to the completion of the model casting, in addition, anti-flux agents can be used to protect the thread.

A variant of the component set is characterized by the claim 4 and differs from the one previously described Component set in that the female part is also the attachment female part forms, which cooperates with an anchor or rod attachment pin, which in turn is held via a threaded section in a cast-on threaded cap which is adapted in their dimensions to the die part.

When using an anchor attachment pin, it is advisable to use a Provide die part with a double-conical course of the inner wall surface, so that the anchor attachment pin is held in a snap-like manner in the die part.

It is advantageous if the die part or the fitting ring of the Sheathing surrounding the die part made from residue-free, combustible plastic on the contact surface for the Male part or for the threaded cap remote side is formed extended beyond the fitting ring. This extension serves as centering when using an additional anchor die part Joining the two die parts together.

With matrices, which consist of a fitting ring and a casing without residue are made of combustible plastic, the plastic is replaced by the metallic when it is cast on Material is replaced, and a ring shoulder is created that protrudes beyond the die part, which is already present in a die part made of full metal. If no additional Anchor die part is provided for the kit, so the said ring shoulder is used for receiving the head of the fastening screw, so that between the screw head and no externally accessible radial gap remains in which the die part When using the prosthesis, food particles can get in.

For the fitting modeling of the die part in or on the corresponding tooth crown on which the female part is cast, it is advisable to if the die part or

the casing surrounding the fitting ring made of residue-free combustible material Plastic laterally next to the fitting ring a protruding in the axial direction of the fitting ring Has molded retaining web. For die parts made of full metal there is also the Retaining bar made of metal, while the other version is made of residue-free combustible plastic exists and when casting through the cast Metal is replaced.

Another variant of the component set is shown in Connection with the patent attachments mentioned at the beginning, with the already Advantages described can be achieved that each soldered connection between the attachment parts and the model casting is omitted and a detachable connection to the removable dental prosthesis held attachments is made possible.

The aforementioned variant results from claim 8. This structural unit leads to the prior art mentioned in the introduction Another significant advantage is that instead of the slotted rings for power transmission closed ring parts are provided, which also increases the accuracy of fit will.

The components shown in Fig. 3 for an anchor attachment are correct with regard to the male part 3 and the female part 2 with the associated casing 1 corresponds to the parts shown and described in FIG. It is for these parts are also given the same reference numerals in FIG. 3.

Fig. 3 shows an anchor attachment pin 7, which instückig with a stepped threaded portion 6 is connected, which is for engagement in the threaded portion 3a of the male part 3 is used. The anchor attachment pin 7 is as resilient Element equipped with one or more longitudinal gaps 7a and is in this For example, provided for snap-in engagement in an additional anchor die part 9. This additional anchor die part 9 is designed similarly to the die part 2 and has a ring part 9a made of platinum / iridium in a casing 10 made of residue combustible plastic on. The inner wall surface 9b of the ring part 9a has a double-conical course and is used for snap-in connection or mounting of the anchor attachment pin 7.

The casing 1 of the die part 2 is in the embodiments according to 1 to 3 formed extended downwards, so that there is an annular Overhang lc arises through which a corresponding one when the fitting ring 2a is cast on metallic protruding edge is formed, in which in the example of Fig. 1 and 2, the screw head 5b takes place.

In the embodiment according to FIG. 3, the protruding edge lc is used for Recording of the additional anchor die part 9, which with its ring part 9a engages in the protruding edge lc before the fitting ring 2 and the ring part 9a together be cast onto the crown of the tooth adjacent to the dental prosthesis. In the area of the retaining web Ib of the casing 1, a bore 8 is provided in which the with the casing 10 of the additional die part 9 connected pin 8a at Joining the die parts 2 and 9 engages.

In the illustrated design of the components for a rod attachment According to FIG. 4, a die part 2 is in accordance with the previous figures a fitting ring 2a and the associated casing 1 is provided, the fitting ring in this case is used to accommodate a rod pushing pin 13. This is equipped with slots 13a to achieve a spring effect, similar to this has been described in connection with the anchor pin 7 of FIG. On the rod attachment pin 13 is connected in one piece to a threaded extension 12, which in the thread 4 of the hollow cylindrical section 11a of the threaded cap designated as a whole by 11 can be screwed in. The threaded cap 11 is supported in the assembled state of the in Fig. 4 reproduced parts with its lower in Fig. 4 protruding outward Shoulder llc, which is designed in the form of an annular collar, on the fitting ring 2a or If the fitting ring is cast on, also on the metal surrounding the fitting ring. In the assembled The rod attachment pin 13a becomes state due to its resilient effect and fitting frictionally held in the fitting ring 2a.

The threaded cap 11 is just like the male part 3 with one of the threaded portion 11a equipped sprue portion 11b protruding axially.

The parts shown in Fig. 5 partly agree with those in Fig. 3 reproduced and partly with the components reproduced in Fig. 4 coincide.

According to FIG. 5, a threaded cap 11 as shown in FIG. 4 is provided, in which an anchor attachment pin 7, which corresponds to FIG. 3, with its threaded attachment 6 can be screwed in.

According to FIG. 5, a die part is used to hold the anchor attachment pin 7 9, which has a ring part 9a and a casing 10 made of residue-free combustible Has plastic, and which of the formation of the additional die part 9 corresponds to FIG. 3.

In the embodiments of FIGS. 3 to 5, the respective reproduced Matrix parts 2 or 9 at the same time attachment matrices in which the anchor or Rod attachment pin 7 resp.

13 Finding a recording.

The die parts 2 and 9 shown in FIGS. 1 to 5 can with the same shape instead of a fitting ring 2a or ring part 9a in connection with a jacket 1 resp.

10 also consist entirely of platinum / iridium5 so that these exclusively Die parts made of metal form the fitting ring 2a or the ring part 9a. This eliminates the burning of the plastic sheaths when casting, however a much larger amount is required for this massive formation of the die parts of the relatively expensive castable platinum / iridium required than this in the examples described so far is the case.

In Fig. 6 a further variant of the new set of components is shown, in connection with a patent attachment.

According to FIG. 6, the component set includes a male part 3 which is identical to the male part 3, as shown in FIGS. 1 to 3 and has been described above.

This component set also includes a die part 17, which has a cylindrical fitting ring 2a like the die parts 2 described or forms and represents a structural unit with an attachment patrix 18. In the illustrated In the example, it is assumed that the attachment patrix is a patrix for a T attachment. The die part 17, which is designed as a structural unit, consists from a mouth-resistant metallic material, for example a gold or Platinum alloy. The fitting ring 2a of the die part 17 is already used in the context with the other figures described manner for receiving the threaded portion 3a of the male part 3, in the manner also described by the retaining screw 5, the female part 17 and the male part 3 are held in their engaged position will.

The attachment male 18 in turn serves to engage in an attachment female, which are cast on the fixed crown of the abutment tooth in a known and customary manner will.

The male part 3 of the component set according to FIG. 6 is the same Way, as has already been stated in connection with the other figures, cast onto the model casting.

For casting the male parts 3 or the threaded caps 11 are used for all Embodiments of the component combinations described in FIGS. 7 and 8 illustrated duplicates.

7 shows an auxiliary duplicating part designated overall by 14 again, which can be formed either in one piece or in two parts and one has cap-shaped embedding section 14a in connection with an integrally formed or can be inserted into a corresponding recess in the embedding section 14a further section 14b, which in its outer dimensions of the outer contour of the Thread section 3a of the male mold 3 corresponds.

8 shows an embedding section 14a of the auxiliary duplicating part 14 Corresponding cap part 15, which can be plugged onto the sprue section 3b of the male mold 3 shown in FIG. 8 as well as for plugging onto the cap 11 of FIGS. 4 and 5 is used, as indicated by dash-dotted lines in the cap part 15 is.

Finally, Fig. 9 shows the in the male part 3 or in the Cap part 11 screw-in fixing screw 16, which on the one hand serves to protect the Thread 4 and on the other hand for fixing the male part 3 or the cap part 11 is used for molding and casting on the aforementioned parts. The fixing screw is usually screwed together with the male part 3 or the cap part 11 Delivered as a unit, with an additional one through the use of fluxes protection of the thread 4 of said parts is guaranteed.

The interaction of the parts described and the particularly simple one as well as for all possible uses the same type of processing is from the the following explanations.

To produce the desired connection of the dental prosthesis with the adjacent tooth crowns by means of the components described is when using a Ring-shoulder-pin attachment the die part 2 with its fitting ring 2a and his Sheathing 1 including parts 1a and Ib to the secondary part of the ring-shoulder-pin attachment, the Conical or telescopic crown, mesial, distal or bilateral using a parallelometer placed directly above the gingiva. With the anchor and rod attachment described the attachment of the die 2 or 9 or the connection of the dies takes place 2 and 9 also extracoronally to the wax model of the abutment crown on the same way.

In the usual process, it is now cast embedded and reworked.

The fitting ring 2a should be covered with protective varnish during post-processing are5 so as not to impair the accuracy of fit.

In the case of the patent attachment described, the attachment matrix is attached also to the wax model of the abutment crown, and it is done in the usual way Way, the matrix of the patent attachment is cast onto the abutment crown.

The preparatory work for duplicating is also carried out, as if you were processing a common anchor. So it becomes the space between the matrix part and the gingiva filled with wax and space for Plastic saddles created. With the duplicating aid 14a, which with its section 14b is pushed into the die part 2, is duplicated in the usual way.

After removing the model from the duplicating material, the the fixation screw 8 connected patrix 3 or with the aforementioned fixation screw 8 connected threaded cap 11 together with the cap part 15 in the duplicating material inserted where previously the duplicating aid 14a was fixed.

Due to the shape of the two matching cap parts 14a and 15 as well as the section 14b of the duplicating aid 14 and the hollow cylindrical section 3a, the male part 3 that can be cast on is securely fixed. When using the threaded cap 11 instead of the male part 3, the threaded cap 11 is securely fixed by the section 16a of the fixing screw 16 which can be seen in FIG. 9, which is shown in FIG its outer circumference is adapted to the inner diameter of the fitting ring 2a.

After the duplicate model has been produced, the cap part 15 is pulled off and the model hardened.

The cast-on male part 3 or the cast-on threaded cap 11 is modeled into the model casting. After casting, the model casting is done in the usual way Way edited. The fixing screw 16 is then removed from the molded male part 3 or the cast threaded cap 11 and screwed through the retaining screw 5 or the threaded section 6 or 12 in the thread 4 of the male part 3 or the cap part 11 screwed in anchor or rod attachment pin 7 or 13 replaced.

The foregoing shows that for all possible designs and applications of the components the duplicate parts are only required once and can be used over and over again.

The invention is with only a few prefabricated components for different Attachment designs can be used, always following the same instructions can be worked. A screw connection is always carried out in such a way that the activatable interchangeable connecting elements on the removable dentures are kept and without major difficulties and time-consuming edits can be replaced. With the component set in the versions described many of the known sources of error and risks that were already in the preparatory work kick off, turned off and a fitting execution of the detachable connection between the Dental prosthesis and the adjacent tooth crowns achieved.

The individual parts of the component set can be coordinated with one another are made in different sizes, but experience shows that three different sizes are enough to accommodate all needs.
