Implant system and method for implanting a dental implant

description

The invention relates to an implant system and a method for implanting a dental implant.

Implant systems of titanium alloys are known which consist of a

Implant root or an implant post and attachable thereto abutment or abutment exist. The dentures, such as the crown, is then modeled on the introduced body part. The implant root usually has a thread, so that it finds support in the spongy, porous bone. Usually, the following steps are necessary in setting a corresponding implant: a) extraction of the existing tooth;

b) healing of the extraction alveolus;

c) if necessary bone augmentation measures;

d) setting the implant root;

e) healing the implant root;

f) introduction of the body part / abutment;

g) Applying the crown.

DE 10 2008 053 104 A1 discloses an implant system which significantly accelerates the implant implantation process and sometimes leads to better results.

The corresponding implant system is in two parts and includes one

Coil spring and an implant body with arranged thereon body part. It is therefore a two-part implant, wherein the coil spring is introduced more or less immediately after the extraction of the original tooth, heals and then after a sufficiently long

Einheilintervall the implant body is screwed into the coil spring. Corresponding implant systems lead to a better fatigue strength. Nevertheless, these implant systems have various disadvantages, since the introduction of the implant body in the coil spring is a complex process in which healed tissue and healed bone must be broken.

Based on this prior art, the present application has the object to provide an improved implant system. In particular, the strength of the implant should be increased and the necessary effort for setting the implant should be reduced. Special care should be taken to minimize the risk of infection.

In addition, a method for implanting a dental implant is to be specified.

The object is achieved by an implant system according to claim 1 and by a method according to claim 14.

In particular, the object is achieved by an implant system with a healing aid, wherein the healing aid comprises:

- A threaded portion with an external thread for insertion into a threaded basket;

- A bone section with a, preferably smooth, outer surface;

Closure section which is arranged between the threaded section and the bone section and has a maximum diameter which is larger, in particular larger by at least 3%, than a maximum diameter of the threaded section.

An essential aspect of the present invention is therefore to provide a Einheilhilfe, which can be screwed into a previously introduced threaded basket.

This healing aid prevents bone cells from getting inside the body

Locate the threaded basket in places that must be bone-free when placing the implant body. The Einheilhilfe thus serves as a placeholder and avoids so that when setting the implant body a new trauma is generated. The implant system according to the invention also avoids the danger that the Free-drilling the interior of the threaded basket of the threaded basket, in particular its internal thread is damaged reduced. In the worst case, in this scenario, the threaded basket can get caught with the drill so that it is torn from the resulting bony anchorage.

The healing aid thus leads to an improved fit of the implant and minimizes the risk for the patient.

Furthermore, the time required to place the implant is reduced (re-drilling is unnecessary). Eventually, the risk of losing that

Implant system is damaged when placing the implant, so that the cost of treatment are significantly lower.

One aspect of the present invention is that the healing aid comprises a bone section. This bone section protrudes in the arranged state (healing aid is screwed into the threaded basket as far as it will go) in the longitudinal direction of the healing aid beyond the threaded cage. In this respect, the implant system according to the invention prevents not only the ingrowth of the bone into the interior of the threaded basket but also above the threaded basket. The bone section is preferably dimensioned such that it projects up to or slightly beyond the bone crest. The healing aid retains a channel over which the implant body can be inserted.

Preferably, the bone portion and / or the closure portion have a maximum diameter that is significantly greater than the maximum diameter of the threaded portion. For example, the maximum diameter of the

Closing portion and / or the bone portion 2 to 15% greater than the maximum diameter of the threaded portion. Preferably, the

Maximum diameter of the closure portion and / or the bone portion 2 to 10% greater than the maximum diameter of the threaded portion. In one embodiment, the maximum diameter of the closure portion corresponds to that of the bone portion. According to the invention but also the

Maximum diameter of the bone section to be greater than that of the

Closing section. In one embodiment, the healing aid is integrally formed to prevent periodontal disease. Furthermore, the corresponding Einheilhilfe can be made easier.

In one embodiment, the closure portion of the healing aid has a

Cone shape. The diameter of the closure section thus increases at least in sections in the direction of the mucosa section. This leads to a complete closure of the threaded basket in the arranged state. Furthermore, a positive connection to the threaded basket can thus be produced at a defined location, which prevents ingrowth from above into the threaded basket. In one embodiment, the threaded basket has a

corresponding section on.

Preferably, the cone shape of the healing aid is configured such that a part of the cone shape in the arranged state of the healing aid projects beyond an upper edge of the threaded basket. The diameter of the healing aid thus increases even in a region which is located outside the threaded basket in the arranged state. Preferably, the implant body is in a similar manner

educated. The implant body may therefore also have a cone shape, which in the arranged state of the implant body over the upper edge of the implant body

Thread basket protrudes. This has advantages in terms of osseointegration as well as the overall stability of the implant system

The bone portion of the healing aid may have a cylindrical shape.

Preferably, the outer surface of the bone portion is as smooth as possible in order to greatly reduce osseointegration during the healing phase.

According to the invention, the surface and / or the material of the healing aid can be chosen such that it does not lead to a regression of the bone.

The closure portion may comprise a conical portion which extends (rotationally symmetrical) with respect to the longitudinal axis along an angle of 5 to 20 °, preferably about 15 °.

The healing aid can comprise a tool holder for screwing in the healing aid. Theoretically, this tool holder can be any

Be tool holder, which is adapted to form a positive connection with a suitable tool. According to the invention may be a Inner polygon or an external polygon act. Preferably, a polygonal socket is used.

The implant system may include a threaded basket. Preferably, this threaded basket has a corresponding to the external thread of the healing aid

trained internal thread. The threaded basket can also be made from a

Titanium alloy to be made. Preferably, the threaded basket is designed such that with the applied forces a certain elongation can take place.

The threaded basket may have an external thread to allow screwing into the bone. In one embodiment, the diameter of the external thread (towards the top) increases. In this respect, the external thread of the

Threaded basket conical. In contrast, the internal thread of the threaded basket can have a constant diameter (cylindrical shape).

In one embodiment, the external thread has exactly one

External thread on. In other embodiments of the invention, a plurality of external threads are provided. This helps to improve the fit of the threaded basket in the bone and allows faster screwing in of the bone

Threaded basket. For example, exactly two external threads

be provided.

For example, the outer diameter of the external thread can increase by more than 2%, in particular by more than 4%, in particular by more than 6%.

Preferably, recesses or openings in the threaded basket

intended. In one embodiment, these recesses extend completely through the (outer) wall of the threaded basket, so that penetration of bone cells through the wall is possible. This consolidates the seat of the

Thread basket in the bone. The Einheilhilfe keeps during the ingrowth of the bone areas within the threaded basket free, which must remain free for a trauma-free introduction of the implant body.

The recesses may be slots that are provided in the thread of the external thread. Preferably, these slots follow the thread. The threaded basket may include at least one indwelling channel on an inner side of the threaded basket. Preferably, several ingrowth channels are provided along the inside of the wall of the threaded basket. These may extend and / or be milled parallel to the longitudinal axis of the threaded basket. The production by means of a milling cutter prevents the threaded basket from causing debilitating microcracks.

In one embodiment, at least some of the recesses open into the at least one ingrowth channel. The ingrowth channel thus provides for the penetrating through the recess bone cells cavities in which the bone cells can settle.

In one embodiment, several, for example, two or four,

Einwuchskanäle a tool holder to screw the threaded basket in the bone. The Einwuchskanäle are therefore suitable to produce a positive connection to an insertion tool.

The multiple ingrowth channels are preferably axisymmetric to

Longitudinal axis arranged.

In one embodiment, the threaded basket comprises at least one,

preferably two, thread-free outer section (s). The at least one unthreaded outer portion preferably extends in the longitudinal direction of the threaded basket and interrupts the male thread or sections. In one embodiment, the unthreaded portion is substantially rectangular in shape and / or extends the entire length or height of the threaded basket (from the threaded basket top edge to the threaded basket bottom edge). In one embodiment, the thread-free portion extends over at least 50%, in particular at least 70% of the total length of the

Threaded basket.

The interruption of the external thread can transversely over

extend at least 2 degrees. The interruption or the unthreaded

Outside section follows in cross section preferably the arc of the

Threaded basket. In one embodiment, the thread-free outer portion is arranged on the outside of the threaded basket in the middle between two Einwuchskanälen. This has the advantage that the threaded basket remains stable despite the material removal that may be necessary for the creation of the thread-free outer section.

Generally, the unthreaded outer section contributes to better osseointegration. Furthermore, the thread-free outer sections after the act

Inserting the threaded basket as a rotation protection and effectively prevent the unwanted loosening of the implant.

In one embodiment, at least one of the unthreaded outer portions is arranged such that it extends centrally between adjacent recesses, in particular the oblong holes.

In one embodiment, there are exactly two thread-free outer sections, wherein these are point-symmetrical to the longitudinal axis of the threaded basket.

Preferably, the implant system comprises an implant body. Of the

Implant body may include a crown portion for receiving a crown, a bone portion, which preferably sits in the bone, a closure portion for at least partially contacting the threaded basket and a threaded portion for screwing into the threaded basket. In addition, it is also possible to provide a mucosal section which lies between the crown section and the bone section and is surrounded by the mucosa when inserted.

In one embodiment, the closure portion of the implant body has a cone shape. The diameter of the closure section widens at least in sections in the direction of the bone section. Of the

Closure portion of the implant body may be formed corresponding to a corresponding portion of the threaded basket. Preferably, the closure portion is at least partially used to produce a positive connection, possibly even to produce a frictional connection with the

Threaded basket. The closure section allows a rotation-resistant

Make connection between the implant body and the threaded basket. Preferably, the material properties of the implant body and the Threaded body chosen such that when screwing in the implant body cold welding occurs.

Preferably, the threaded basket is made of a much softer material, for. As a titanium alloy with Grade 4, as the implant body, z. For example, grade 5 titanium alloy. In one embodiment, the threaded basket is designed such that upon insertion of the implant body a deformation in the transverse direction (to the longitudinal axis of the threaded basket) occurs. Due to the

Deformation may cause the threaded basket to become wedged in the bone. In this embodiment, therefore, there is a double adhesion: a) between bone and threaded basket; b) between threaded basket and implant body.

The mucosal portion of the implant body may include an edge that projects significantly beyond the bone portion in the radial direction. Thus, a maximum diameter of the mucosa portion may be significantly greater (e.g., greater than 2%, 3%, or 4%) than the maximum diameter of the mucosa

Bone section is. The crown can be set up on this edge.

Preferably, the maximum diameter of the mucosa portion with the edge is at most 120%, in particular at most 115%, of the maximum diameter of the bone portion of the implant body, so that a sufficient distance to the adjacent teeth can be maintained.

Starting from an upper side of the edge, a height of the crown section can be specified. According to the invention, this height may be less than 5 mm, in particular less than 4.5 or 4 mm. In one embodiment, the height is less than 3.8 mm. The low height ensures that the inserted implant body does not project beyond the neighboring teeth. Furthermore, it offers the possibility of additionally attaching an abutment to the implant body.

The implant body and the associated threaded basket can be designed such that a lower edge of the implant body is seated in the arranged state within the threaded basket. In this respect, the implant body does not protrude down beyond the threaded basket. This prevents loosening of the threaded basket when screwing the implant body into the threaded basket. Additionally or alternatively, the healing aid can be designed such that a lower edge of the healing aid in the arranged state protrudes beyond the lower edge of the threaded basket. In this respect, when healing the threaded basket, in which the healing aid is screwed, a kind of reservoir is created in the bone, which can absorb excess cell material and liquid when introducing the implant body.

The healing aid may comprise at least one predetermined breaking point in the bone section. This predetermined breaking point can serve to dimension the healing aid in situ or in advance in a suitable manner. According to the invention, the

Einheilhilfe be shortened so that an upper edge of the healing aid concludes with the bone crest of the patient or just below or just above the bone crest. Preferably, the healing aid is dimensioned by means of the predetermined breaking point at least so that the upper edge through the

Gums can be covered. This can ensure healing in a sterile environment.

In one embodiment, a plurality of predetermined breaking points are provided. The predetermined breaking points can be designed annular. The predetermined breaking points can be created by removing and / or perforating the existing material. According to the invention, all known methods for producing the predetermined breaking points can be used.

The healing aid may include a thread for attaching a closure cap. This cap can serve, for example, the

Close tool holder in a suitable manner.

The above-mentioned object is further achieved by a method for implanting a dental implant. Preferably, the method comprises the following steps: a) introducing, in particular screwing, a threaded basket in the

Bone of a patient; b) introducing, in particular screwing, a Einheilhilfe (30) in the

Threaded basket; c) removing the healing aid for introducing an implant body, wherein the introduction of the implant body, preferably in such a way that a cold welding between the implant body and the threaded basket takes place.

There are similar or identical advantages as have already been described in connection with the device.

The invention will be described by means of an embodiment which is explained in more detail with reference to figures. Hereby show:

1 shows a threaded basket 20 of an implant system 10 according to the invention (FIG. 11). For the description of the implant system 10, the terms "top" and "bottom" are used below. The locations refer to the implant system 10 in the assembled state, with coronal areas or directions at the top and radicular and apical areas or directions at the bottom.

The threaded basket 20 is substantially a straight circular cylinder formed around a longitudinal axis with a height (along the longitudinal axis) of about 6.5 mm and a wall thickness (without threading) of about 0.1 to 1 mm, wherein the cylinder a External thread 21 and an internal thread 23 (see Fig. 4) is provided. The cylinder has a diameter of about 4 mm.

As can be seen with reference to FIG. 5, the threaded basket 30 has a threaded basket lower edge 27 and a threaded basket upper edge 28. In the shown

Embodiment, the outer diameter of the outer thread 21 increases starting from the threaded basket lower edge 27 toward the threaded basket upper edge 28. For example, can be started with a diameter of 4.5 mm and completed with a diameter of about 5 mm. Accordingly, the outer wall of the threaded basket 30 may be slightly tapered.

Preferably, the internal thread 23 has a constant internal thread diameter over the entire length.

The threaded basket 20 has a plurality of recesses 25, 25 '(see Figures 1 and 2), on which the cylinder is interrupted or perforated. The

Recesses 25, 25 'are preferably arranged in the external thread 22 and are in a plan view (Fig. 3) at 0 °, 90 °, 180 ° and 270 °. Fig. 7 shows a section through the 90 and 180 ° Ausussungen 25, 25 \

In contrast, Fig. 4 shows a staggered by 45 ° section.

The sections according to FIGS. 4 and 5 illustrate that the internal thread 23 is only provided in sections within the threaded basket 20 in order to

thread-free sections - so-called Einwuchsabschnitte - create, in which the recesses 25, 25 'open. This allows the ingrowth of the bone into the interior of the threaded basket, whereby the function of the threaded basket 20 is not impaired (the internal thread and considerable sections within the threaded basket 20 remain free, so that the implant body can be introduced trauma-free after completion of the healing phase.).

6 shows an embodiment of the healing aid 30 according to the invention. As a result, the healing aid 30, viewed from the bottom to the top (along the longitudinal axis), first has a cylindrical section, then a conical section and then again a cylindrical section. The lower cylindrical portion is at least partially provided with a thread, namely the Einheilhilfe thread 40. The upper cylindrical portion forms a healing aid head 60. The healing aid head 60 has no threads. Preferably, the surface of the healing aid head 60 is relatively smooth to inhibit osseointegration upon healing. The Einheilhilfe 30 can thus be easily removed even after a longer healing period in the tissue and bone.

The healing aid head 60 has a first predetermined breaking point 62 and a second predetermined breaking point 62 ', which extend annularly in the upper half of the healing aid head 60.

Functionally, the healing aid 30 can be in at least three sections, namely a threaded portion 31, a closure portion 32 and a

Subdivide bone section 33. The threaded portion 31 serves to screw the healing aid 30 into the threaded basket 20. The Einheilhilfe thread 40 and a Einheilhilfe-external thread 41 is for this purpose corresponding to the internal thread 23 of the threaded basket 20 is formed (in the described

Embodiment with constant external thread diameter). The closure section 32 comprises, at least in sections, the conical section which produces a positive connection with the threaded cage 20 in the arranged state.

The bone section 33 is surrounded by the bone in the arranged state of the implant system 10. In order to prevent protrusion of the healing aid head 60, the predetermined breaking points 62, 62 'are provided, which make it possible to shorten the healing aid 30 (see Fig. 9).

FIG. 7 shows a longitudinal section through the healing aid 30 according to FIG. 6. On the basis of this longitudinal section, it can be seen that the healing aid 30 in its interior, in particular at the level of Einheilhilfe head 60 a

Tool holder 61 in the form of a polygon (see Fig. 8). At the level of the closure portion 62 and the threaded portion 61 is a coping thread 35 which adjoins the tool holder 61 and is adapted to receive a coping (not shown) to the

Close tool holder 61.

In the described embodiment, the Einheilhilfe external thread 41 has a constant outer diameter. A maximum diameter mdG of the

Threaded portion 31 is significantly smaller than a maximum diameter mdV of the closure portion 62. The diameter of the bone portion 33 substantially corresponds to the larger diameter of the closure portion 62, so that a maximum diameter mdK of the bone portion 33 is equal to

Maximum diameter mdV of the closure portion 42 is.

FIGS. 10 and 11 show the healing aid 30 in an arranged state. In the described embodiment, the healing aid lower edge 37 protrudes beyond the threaded basket lower edge 27. It results in a supernatant dÜ. This supernatant dÜ can be 0, 1 to 2 mm. Preferably, the supernatant dÜ is in the range between 0.2 and 1 mm.

Furthermore, FIG. 10 shows that the conical section of the

Closure portion 32 is not completely absorbed by the threaded basket 20. In this embodiment, the closure portion 32 is defined to start at the location where the conical portion of the

Bone section 33 merges into the cylindrical section. Alternatively, the closure portion 32 may be defined to refer to the area on the healing aid 30 which has no thread and is disposed within the threaded cage 20 (as far as the threaded cage upper edge 28). Accordingly, the bone portion 33 may extend from the threaded basket upper edge 28 to the upper end (healing aid upper edge 38).

FIGS. 12 and 13 show an implant body 70 in the arranged state, namely in a state screwed into the threaded basket 20. According to the invention the Einheilhilfe 30 serves during the healing phase as a placeholder for the

Implant body 70, which carries the actual superstructure, such as a crown. With reference to FIGS. 12 and 13, it can be seen that the

Implant body 70, unlike the Einheilhilfe 30, in the assembled state does not protrude beyond the threaded basket 20. An implant body lower edge 77 is positioned slightly offset from the threaded basket lower edge 27, so that no protrusion occurs.

The implant body 70 has five sections in the exemplary embodiment described, namely (from bottom to top):

a threaded portion 71,

a closure portion 72,

a bone section 73,

a mucosa section 75,

a crown section 74.

The threaded portion 71, the closure portion 72 and the bone portion

73 have a cylindrical, a conical and turn a cylindrical shape. The closure portion 72 completely includes the cylindrical shape. Of the

Threaded portion 71 has a thread, which in turn is formed corresponding to the internal thread 23 of the threaded basket 20. The bone portion 73 is cylindrical and passes through the mucosa portion 75 and the crown portion

74 added.

In one embodiment, the bone portion 73 of the implant body 70 is significantly rougher than the bone portion 33 of the healing aid 30, so that the Osseointegration of the implant body 70 is increased. For example, the bone portion 73 of the implant body 70 may be blasted and / or etched while the bone portion 33 of the healing aid is untreated. In one embodiment, this portion of the healing aid may also be polished to prevent osseointegration as much as possible.

Also, the implant body 70 may have an internal thread to

For example, to record a body part or the introduction of the

To facilitate implant body 70.

In one embodiment, the external thread 21 has a plurality

External threads 22, 22 'on. A corresponding embodiment is shown in FIGS. 14 and 15, wherein here a first external thread 22 and a second external thread 22 'are provided. As can be seen with reference to FIG. 15, the external threads 22, 22 'start offset by 180 degrees at the threaded basket upper edge 28 and extend over the entire outer surface of the threaded basket 20. The threads 22, 22' are substantially parallel to each other.

In the embodiment shown in Figs. 14 and 15 also unthreaded outer portions 29, 29 'are provided. These threadless

Outer sections 29, 29 'need not necessarily be used in conjunction with a plurality of threads 22, 22'. The positive effect when healing the threaded basket 20 also occurs when only, as in the

Embodiment of FIG. 1, a single external thread 22 is provided.

In the embodiment shown in FIGS. 14 and 15, the unthreaded outer portions 29, 29 'extend along the longitudinal direction of the

Thread basket 20 of the thread basket bottom edge 27 to the threaded basket upper edge 28 - ie over the entire length. It can be seen from the plan view according to FIG. 15 that the thread-free outer sections 29, 29 'are substantially axially symmetrical with respect to the longitudinal axis of the threaded basket 20

are arranged and formed. If one assumes an arrangement of

Recesses 25, 25 'in the external threads 22, 22' at 0 degrees, 90 degrees, 180 degrees and 270 degrees (in plan view), so run the unthreaded outer portions 29, 29 'in the embodiment shown at 45 and 225 degrees. In this respect, the thread-free outer sections 29, 29 'extend parallel to the bores, which are necessary to create the recesses 25, 25'. The staggered arrangement of the unthreaded outer portions 29, 29 'relative to the holes for the recesses 25, 25', the high stability of

Maintain threaded basket 20.

The thread-free outer portions 29, 29 'promote the osseointegration of the threaded basket 20. Furthermore, the outer portions 29, 29' act after the introduction of the threaded basket as rotation protection and effectively prevent the unwanted loosening of the implant.

According to the invention, the thread-free outer sections 29, 29 'can be produced by an abrasive method, for example by milling a groove.

According to the invention, it is possible to provide one, two, three, four, five, six, seven, eight thread-free outer sections 22, 22 '. Preferably, two, four or eight thread-free outer sections 29, 29 'are provided. The unthreaded outer portions 29, 29 'need not necessarily extend over the entire length of the threaded basket 20. Preferably, the thread-free

Outer sections 29, 29 ', however, designed such that they interrupt all external threads 22, 22' in one segment. In another embodiment, take the unthreaded outer portions 29, 29 'in the longitudinal direction of

Thread basket 20 considers at least 50%.

In the embodiment shown in Fig. 14 extend the

Threads 22, 22 'not over the entire length of the threaded basket 20. The upper portion of the threaded basket 20 (near the upper edge 28) is thus thread-free. The absence of the last segment serves to widen the upper portion of the threaded basket 20. This measure for bone compaction during

Inserting the threaded basket 20, creating a faster and better

Osseointegration is achieved.
