Description

[0001] Multifunctional implant system and method for individually adapting at least one implant of an implant system

[0002] The invention relates firstly to a multifunctional implant system with at least one implant according to the features of the preamble of patent claim 1.

[0003] The invention further relates to a method for individually adapting at least one implant of an implant system, in particular of the aforementioned type.

[0004] So-called one-piece and multi-piece implant systems are known in the prior art. In one-piece implant systems, a crown is arranged and / or fastened and / or connected directly to the implant head of the implant without any further intermediate components. In multi-piece implant systems, an intermediate component, namely in particular an abutment, is first arranged and / or fastened to the implant head and / or connected to the implant head, with the crown then being arranged and / or fastened to the abutment and / or connected to the abutment. Accordingly, the implant head of a one-piece implant system - in the connected and / or fastened and / or arranged state of the implant body with or on the jawbone - generally protrudes further from the jawbone than the implant head of a multi-piece implant system.

[0005] DE 10 2020 210 075 A1 discloses an implant of a one-piece implant system with an implant body and an implant head. Such an implant is typically made of metal or ceramic. The purpose of this already known implant system is to enable a particularly cost-effective design of the implant with particularly diverse combination options, including additional components, in particular a crown and / or an abutment. For this purpose, the implant head has, for example, an internal thread, so that an abutment or a crown can then be flexibly and effectively connected to the implant by means of an adhesive or, in particular, a screw connection. The implant head has a non-circular cross-section, preferably an external hexagon, to enable easy screwing of the implant into the jawbone using an external tool adapted to the cross-sectional shape of the implant head.Particularly in the case of failed osseointegration, i.e. failed healing, the external tool can be placed back on the implant head and osseointegration can be "activated" again by screwing the implant in further. When screwing the implant into the jawbone, it is problematic that the areas of the gingiva and / or jawbone adjacent to the tool and / or adjacent teeth may be touched by the tool during screwing in, which complicates the process of screwing the implant into the jawbone. This problem arises in particular when the implant head of the implant of a multi-part implant system - when connected and / or fastened and / or arranged by the implant body with or on the jawbone - protrudes only slightly from the jawbone.

[0006] EP 3 235 465 B1 describes various embodiments of an implant of a known implant system. For example, a one-piece embodiment of the implant system with an implant consisting of an implant body and an implant head, wherein the implant head is designed accordingly for the direct attachment of a crown. The implant has an internal thread for attaching the crown and / or an abutment. Alternatively, implants without a pronounced implant head are described which, in addition to the internal thread, have a connecting area. The implant can then be connected to the abutment by means of this connecting area and are therefore designed as a multi-part implant system. In this case, the crown is therefore connected to or on the jawbone or, as a result of the non-pronounced connection - in the connected and / or fastened and / or arranged state - of the implant body.Because the implant head only protrudes slightly from the jawbone, it cannot be directly connected to the connection area and / or arranged and / or secured there. The possible combinations of each of these implants with other superstructures / components, such as an abutment, a connector, a crown, and / or a temporary prosthesis, are therefore limited.

[0007] The invention is therefore based on the object of designing and / or developing a multifunctional implant system or a method for individually adapting at least one implant of an implant system in such a way that the aforementioned problems and / or problematic aspects are avoided and / or reduced, in particular wherein the combination options of the implant of this implant system with regard to further structures / components, such as an abutment, a connector, a crown and / or a temporary prosthesis are expanded and / or the implant system can be optimally adapted to the individual patient, in particular the application possibilities and / or the flexibility of such an implant system are increased. This object underlying the invention is now initially achieved by a multifunctional implant system with the features of patent claim 1.

[0008] One aspect of the invention essentially lies in the fact that the implant head is designed to be grindable. A further aspect of the invention is that a recess is formed in the implant along its longitudinal axis, which recess is open towards the implant head, wherein the recess is designed at least partially for the positive arrangement and / or for the positive engagement of a tool, in particular at least partially as a polygonal profile or as an internally rounded profile, so that the implant can be screwed into the jawbone with the aid of the tool. A further aspect essentially lies in the fact that the recess at least partially has an internal thread. This then makes it possible to connect and / or fasten and / or arrange an additional, further structure of the implant system, such as in particular an abutment, a connector, a crown and / or a temporary prosthesis, with or on the implant using a retaining screw.Thus, the possible combinations of the implant of this implant system with the additional structures / components, such as abutments, connectors, crowns, and / or temporary prostheses, are further expanded. A further aspect of the invention is that the implant system comprises at least one ring, in particular a metal ring, wherein the ring can be supported on the implant and / or arranged such that a portion of the implant head protrudes from the ring. The then protruding portion of the implant head can be ground down to the ring supported and / or arranged on the implant using a grinding tool.This multifunctional implant system designed in this way creates a particularly high level of flexibility. In particular, the implant can be individually adapted to a specific patient, particularly because the implant head can be easily adapted and / or dimensioned to the respective needs using the ring and the grinding tool. For this purpose, the implant system can in particular have rings of different dimensions, in particular of different axial lengths or heights. The implant head can now be machined in such a way, as the following explanations will show, that the implant head can then be easily adapted and / or designed to suit the respective needs of a patient, in particular for the connection and / or fastening and / or arrangement of the additional further structure of the implant system.

[0009] This expands and improves the combination options for the implant of this implant system with additional structures / components, such as an abutment, a connector, a crown and / or a temporary prosthesis. In particular, the implant can be used in a one-piece implant system, whereby a crown can be arranged and / or fastened directly to the implant head without further intermediate components and / or can be effectively connected to the implant head. On the other hand, the implant head of the implant is designed to be grindable, so that after grinding, a crown can also be arranged and / or fastened to the implant head and / or can be connected to the implant head by means of an intermediate abutment, whereby the implant then forms part of a multi-piece implant system.Depending on the application of the implant, connectors for effective connection to a healing cap and / or temporary prostheses with or without an intermediate abutment can be arranged and / or fastened to the implant head and / or connected to the implant head. In particular, due to the grindability of the implant head, the implant or the implant system can be individually adapted to a specific patient and / or optimally adapted. Because the recess is at least partially designed for the form-fitting arrangement and / or for the form-fitting engagement of a tool, in particular as a multi-edged profile or as an internally rounded profile, the implant can be screwed into the jawbone with the aid of the tool even after the implant head has been ground down. After grinding down an implant head which has a multi-edged profile on its outer circumference for screwing into the jawbone, such as e.g.As is known from the prior art, further screwing in would no longer be possible after this grinding. In particular, if the implant head has already been ground down, but the implant body has not yet sufficiently grown into the jawbone, i.e., osseointegration has not yet occurred as desired, the tool can then be arranged again in a form-fitting manner in the recess of the implant of the implant system according to the invention in order to "activate" the connection process between the jawbone and the implant body, namely osseointegration, by further, piece-by-piece screwing in the implant.Because additional, further structures on the implant system according to the invention, such as in particular an abutment, a connector, a crown and / or a temporary prosthesis, can be arranged and / or fastened to the implant head and / or connected to the implant head both without grinding and after at least partial grinding of the implant head, a particularly large number of different types of abutments, connectors, crowns and / or temporary prostheses can be arranged and / or fastened to the implant head and / or connected to the implant head. The implant system according to the invention is thus particularly flexible and can be adapted and / or individually adapted particularly well to the respective patient for whom it is to be used. In an advantageous embodiment of the implant system, the polygonal profile is designed as a hexagon socket profile or as a square socket profile.In contrast, the use of internal profiles with three, four, five, or more than six, e.g., seven to ten edges, would also be conceivable. The recess, on the other hand, could also have a star-shaped profile, for example. Due to such polygonal profiles, the torque applied to the implant can be particularly well controlled with the help of the tool, so that screwing the implant into the jawbone is particularly easy and can be carried out with particularly high precision. It is also conceivable that an internal round profile is provided and / or designed for the positive engagement of the tool, in particular the internal round profile is designed as an internal quadrilateral profile.

[0010] The polygonal profile or the inner round profile and the inner thread are preferably formed in different areas, viewed in the longitudinal direction of the implant. In particular, the recess has the polygonal profile or the inner round profile adjacent to its opening. Preferably, the inner thread is formed in an end area of ​​the recess facing away from the opening, preferably adjacent to the polygonal profile or the inner round profile. In contrast, it would also be theoretically conceivable for the polygonal profile or the inner round profile and the inner thread to be formed at least partially in the same area of ​​the recess, viewed in the longitudinal direction of the implant, the inner thread then being partially interrupted in the circumferential direction by the polygonal profile or the inner round profile.

[0011] According to a further preferred embodiment of the implant system, the implant, namely the implant body and the implant head, is designed as a single-piece component. Such a single-piece component is manufactured, for example, using a sintering process and / or by removing material from a homogeneous base body. Single-piece components have the advantage that there are no connecting joints between functionally different subcomponents in which contaminants and / or bacteria could undesirably accumulate.

[0012] Preferably, the implant comprises or is made of a ceramic material, in particular a zirconium oxide ceramic. Such ceramic materials are particularly well-processed in the aforementioned sintering process and are also particularly easy to grind using conventional grinding tools. Furthermore, the necessary stability of the implant is also ensured by the ceramic material, in particular the zirconium oxide ceramic.

[0013] The implant head advantageously has an implant head gingival area adjacent to the implant body. The implant head gingival area is intended and / or designed - when the implant body is connected and / or fastened and / or arranged with or on the jawbone - to be enclosed by gingiva and / or to be in direct contact with the gingiva. The "gingiva" is also sometimes referred to below as "gum". It is possible that immediately after the implant has been screwed into the jawbone, the implant head gingival area is not yet enclosed by the gingiva and / or is in direct contact with the gingiva. The enclosing of the implant head gingival area could then occur during a healing process of the gingiva / gum, so that after the healing process, the gingiva is also in direct contact with the implant head gingival area.at least partially encloses the implant head - gingival area.

[0014] In a further preferred embodiment of the implant system, the implant head has an implant head holding region on the side of the implant head gingival region facing away from the implant body, in particular with a substantially constant outer diameter or with an outer diameter that decreases along the longitudinal axis. The implant head holding region has, in particular, a smaller outer diameter than the implant head gingival region. The aforementioned term "substantially" means, in particular, that in the preferred embodiment described above, where the implant head holding region has a "substantially" constant outer diameter, corresponding manufacturing tolerances are also included. The implant head holding region is therefore preferably cylindrical.The implant head holding area serves in particular to connect and / or fasten and / or arrange the additional, further superstructures and / or further components of the implant system on the implant, wherein these superstructures or components are then in particular in direct contact with the implant head holding area. However, it is also conceivable, for example in a further embodiment, that the implant head holding area is conical or has a conical shape, in particular having a conical outer region. However, even then the then "average outer diameter" and / or the "smallest outer diameter" of this then conical implant head holding area is smaller than the outer diameter of the implant head gingival region. Further preferably, a bevel is formed between the implant head gingival region and the implant head holding area.The transition between the implant head gingival area and the implant head holding area is formed by means of the bevel. The bevel preferably has the shape of the lateral surface of a truncated cone on its outer circumference. Other types of transitions between the implant head gingival area and the implant head holding area would also be conceivable, e.g. with a changing gradient of the bevel with regard to or relative to the longitudinal axis of the implant. For example, a stepped transition between the implant head gingival area and the implant head holding area would also be conceivable, in particular with the formation of several steps or even with the formation of just one step or a shoulder, in particular when the implant head gingival area directly borders on the implant head holding area and the implant head holding area has a smaller outer diameter than the implant head gingival area.

[0015] Preferably, a bead-shaped locator section with an outer diameter that is larger than the implant head holding area is formed on a front end region of the implant head facing away from the implant body. With the aid of the bead-shaped locator section, an additional, further structure of the implant system, in particular a temporary prosthesis, can be arranged on the implant and / or effectively connected to the implant. Commercially available temporary prostheses are particularly designed to be connected to the implant with the aid of such a bead-shaped locator section.Such temporary prostheses must also be removed from the implant again, namely when the healing process of the implant into the jawbone and / or the healing process of the gingiva is complete and a crown for permanent use is to be placed and / or attached to the implant or an intermediate abutment and / or connected to the implant or the intermediate abutment. Removing the temporary prosthesis is particularly easy because its connection to the bead-shaped locator section is largely based on a positive fit, so that the connection between the temporary prosthesis and the implant head can be removed again without the application of significant force. In principle, a "crown" could also fall under the term "prosthesis". The term "prosthesis" therefore generally includes corresponding, in particular already known, "partial tooth replacement components".A prosthesis can therefore also be removed from the patient's oral cavity. However, in particular, a "temporary prosthesis" is inserted into the patient's oral cavity so that after a certain period of time, particularly after the implant has healed into the jawbone, and after the removal of this temporary prosthesis, a crown, for example, can be permanently placed on the implant in the patient's oral cavity in place of the temporary prosthesis. In this case, the crown is usually made of ceramic, although a temporary prosthesis can also be made of plastic.

[0016] Advantageously, the implant head holding area and / or the bevel and / or the stepped transition protrude at least partially from the gingiva when the implant body is connected, secured, and / or arranged to or on the jawbone. This also ensures that the gingiva / gum is not touched by the connection, attachment, and / or arrangement of the additional, further abutments / components of the implant system to the implant, and that the gingival growth process is not disrupted by such additional abutments.

[0017] In the embodiment of the implant system according to the invention, the implant system comprises at least one ring, in particular a metal ring. The ring can be supported on the implant, in particular in the region of the bevel or in the region of the stepped transition and / or in the region of the implant head-gingival region and / or in a groove, and / or can be arranged such that a portion of the implant head protrudes from the ring, wherein the then protruding portion of the implant head can be ground down to the ring supported on the implant using a grinding tool. The ring thus forms a stop for the grinding tool. The grinding process can thus be carried out with particular precision.Furthermore, the shape of the implant head remaining after the grinding process is known with particular precision in its dimensions, so that a subsequent connection and / or fastening and / or arrangement of the further structure / a further component on the implant head is facilitated, in particular the structure itself then no longer needs to be adjusted.

[0018] Further preferably, the implant head has at least one connecting region, in particular a notch or a raised portion, for the positive and / or non-positive arrangement of the ring on the implant and / or for the positive and / or non-positive connection of the ring to the implant. In this way, it can be ensured that the ring—then arranged positively and / or non-positively on the implant or connected to the implant—does not slip during grinding, in particular does not rotate, and in particular is secured against rotation. According to an advantageous embodiment of the implant system, the connecting region extends in the longitudinal direction of the implant head, in particular over the entire implant head holding region and at least partially over the bevel.The ring then has a corresponding elevation or notch on its inner circumference, matching the notch or elevation of the connecting area. The respective notches or elevations extend in the longitudinal direction of the implant or ring. A positive connection between the ring and the implant head can thus be realized between the notch or elevation of the connecting area and the elevation or notch of the ring, which, in particular, prevents rotation of the ring around the longitudinal axis of the implant.

[0019] According to an advantageous, alternative embodiment of the implant system, the connecting area is formed in the region of the bevel, in particular as a circular notch or elevation. The ring then has a corresponding circular elevation or notch on its inner circumference, matching the circular notch or elevation of the connecting area. The ring can then be essentially clipped onto the implant head, wherein, when the ring and implant head are connected, the respective notch at least partially engages the respective elevation.

[0020] In a further advantageous, alternative embodiment, the implant head has at least one guide region, in particular a notch or a groove, and the ring has at least one elevation for engaging in the guide region and / or for enabling targeted, forced guidance of the ring. The guide region extends in the longitudinal direction of the implant head, in particular the guide region extends over the entire implant head holding region and / or at least partially over the aforementioned bevel. In particular, the guide region has a plurality of, in particular four, notches and / or grooves and the ring has a plurality of, in particular four, elevations corresponding thereto formed on its inner circumference. The implant head holding region and / or the bevel has a groove and / or groove-shaped notch that runs at least partially, in particular completely, around its circumference. The elevation or elevations of the ring is or areFor the positive and / or non-positive arrangement of the ring on the implant, in particular for its axial fastening on the implant, they can be screwed into the groove when the ring is appropriately positioned in the guide area, in particular when the ring has reached the end of the guide area in the direction of the longitudinal axis, where the partially circumferential groove adjoins or is correspondingly formed here. This then enables the elevation to be screwed into the groove.

[0021] The ring preferably has a longitudinal height of 0.3 mm to 3 mm, in particular of 0.5 mm to 2 mm. In particular, the ring has a height of 0.5 mm, 1 mm, 1.5 mm, or 2 mm. Using rings of such sizes, the respective implant heads of the desired size can be created by grinding the implant heads down to the upper edge of the corresponding ring, in particular, the respective implant can be individually adapted to the respective individual needs of the patient.

[0022] The object underlying the invention is also achieved by a method for individually adapting at least one implant of an implant system described above, in particular, with the features of patent claim 23.

[0023] One aspect of the invention then essentially lies in the fact that the implant head is at least partially ground down in order to subsequently arrange and / or fasten and / or connect a specific structure and / or another, specific component to the implant. In this case, a ring is first slipped over the implant head and / or over an implant head holding area and / or supported and / or arranged thereon until the ring is supported and / or arranged and / or mounted on the implant, in particular in the area of ​​the implant head holding area and / or in the area of ​​a bevel and / or at a step-shaped transition and / or at an implant head gingival area, such that part of the implant head protrudes from the ring.

[0024] The grinding process increases the number of different types of abutments, connectors, crowns, and / or temporary prostheses that can be arranged and / or attached to the implant head and / or connected to the implant head, as the implant head has a different shape and / or size after partial grinding than before grinding. Other shapes of the implant head are suitable for arranging and / or attaching other abutments, connectors, crowns, and / or temporary prostheses to the implant head and / or connecting them to the implant head. In other words, the implant head can be adapted accordingly, so that the implant system offers a high degree of flexibility.

[0025] Preferably, a centering pin of a grinding tool is arranged in the recess of the implant in order to support and / or center the grinding tool on the implant with the centering pin during grinding of the implant head. In this way, grinding can be carried out with greater precision. In particular, the length of the implant can be reduced in a defined manner in this way, since the grinding tool can be guided and / or supported on the implant in the longitudinal direction of the implant with the centering pin during grinding of the implant head. In particular, because the grinding tool can be guided and / or supported on the implant with the centering pin in the longitudinal direction of the implant during grinding of the implant head, the rotational symmetry of the implant head can also be changed in a defined manner, which will be explained in more detail below.

[0026] In an advantageous embodiment of the method, the bead-shaped locator section, if present, is ground down. The bead-shaped locator section serves, in particular, to arrange and / or secure a temporary prosthesis to the implant and / or connect it to the implant head. When such a temporary prosthesis is no longer needed, the bead-shaped locator section is ground down in order to subsequently arrange and / or secure a specific, different component, such as, in particular, a permanently insertable crown, to the implant and / or connect it to the implant.

[0027] The ring is preferably slipped over the implant head and / or arranged on the implant head until the ring is supported and / or mounted on the implant, in particular in the region of the bevel and / or at a step-shaped transition and / or on an implant head gingival region, so that part of the implant head protrudes from the ring, in particular after the bead-shaped locator section has been ground down. The axial length or height of the ring is therefore smaller than an axial length or height of the implant head, in particular the axial length / height of the ring is smaller than a common axial length of the implant head holding area and any bevel that may be present. Grinding down the bead-shaped locator section is necessary under certain circumstances because the inner diameter of the ring is preferably at least partially smaller than the maximum outer diameter of the bead-shaped locator section.

[0028] In particular, the ring is arranged on the implant, in particular in a form-fitting and / or force-fitting manner, in particular to substantially prevent rotation of the ring during the grinding process and / or movement of the ring in the longitudinal direction of the implant. The previously explained connecting regions and / or guide regions of the implant serve this purpose, wherein, in particular, a protrusion of the ring can be rotated into a partially circumferential groove of the implant, in particular in a substantially form-fitting manner, as previously explained.

[0029] More preferably, the portion of the implant head protruding from the ring is ground down to the ring supported on the implant using a face grinding tool, forming a plateau. This reduces the length of the implant. The plateau forms a plane perpendicular to the longitudinal axis of the implant. The materials of the face grinding tool and the ring are matched in such a way that the ring itself cannot be easily ground down using the face grinding tool. Therefore, when the face grinding tool hits the ring, only minimal abrasion, if any, occurs.

[0030] In a further preferred embodiment of the method, the ring is removed from the implant again after the plateau has been created. The ring is removed essentially along the longitudinal axis of the implant. After removal, a further, different component, such as in particular an abutment, a connector, and / or a crown, can be arranged and / or fastened to the implant head and / or connected to the implant head. By grinding, a further, different component than before grinding can be arranged and / or fastened to the implant head and / or connected to the implant head.

[0031] Advantageously, the outer circumference of the implant head is ground using a circumferential grinding tool, in particular one with a specific inner contour, to create a specific outer contour. Commercially available crowns, in particular, have a specific inner contour, to which the specific outer contour of the implant head is adapted by this grinding. By changing the outer contour, additional, different abutments / components can be arranged and / or attached to the implant head and / or connected to the implant head than before the outer contour was changed. Each grinding process further increases the number of different types of abutments, connectors, crowns, and / or temporary prostheses that can be arranged and / or attached to the implant head and / or connected to the implant head. Therefore, the application possibilities and flexibility of the implant system designed in this way are correspondingly high.

[0032] According to a further preferred embodiment of the method, the specific structure and / or the further, specific component is designed as an abutment, a connector, a crown and / or a temporary prosthesis. The further, specific components are used in particular alternatively and / or in different phases. For example, it is conceivable that a temporary prosthesis is initially arranged and / or fastened to the implant and / or connected to the implant. Before or after this, a healing cap could be arranged and / or fastened to the implant and / or connected to the implant with the aid of a connector. Ultimately, a crown, with or without an intermediate abutment, is usually arranged and / or fastened to the implant and / or connected to the implant. However, it is also conceivable that a bridge is arranged and / or fastened to the implant and / or connected to the implant.In particular, the healing process of a jawbone and / or gingiva can be particularly well controlled and / or supported in all its phases with the help of the implant system.

[0033] Advantageously, the procedure is performed with the implant body connected, secured, and / or positioned to or on the jawbone. Then, particularly if the healing process of the jawbone and / or gingiva is already well advanced, the implant can be modified accordingly to connect, secure, and / or position a specific, additional structure of the implant system. This allows the specific, additional structure to be selected, particularly based on how the healing process has progressed up to that point or the current condition of the jawbone and / or gingiva.

[0034] In another alternative embodiment of the method, the procedure is performed outside of a patient's oral cavity. The grinding processes are easier to perform outside of a patient's oral cavity because the implant is more accessible from all sides.

[0035] There are now a multitude of possibilities for advantageously designing and developing the multifunctional implant system and the method for individually adapting at least one implant of such an implant system. Reference may first be made to the claims subordinate to claim 1 and to the claims subordinate to claim 23. A preferred embodiment of the implant system according to the invention and the method according to the invention for individually adapting at least one implant of such an implant system will now be explained and described in more detail with reference to the drawing and the associated description.

[0054] First, with reference to all of Figs. 1 to 10, the following should be stated: The implant head 4 is designed to be grindable. This grindability is based, on the one hand, on the material of the implant head 4, which is designed to be particularly easy to grind. Furthermore, this grindability is based on the fact that the implant head 4—when connected and / or fastened and / or arranged by the implant body 3 with or on the jawbone 6—protrudes a corresponding distance from the jawbone 6, as shown in particular in Fig. 2.

[0055] A recess 7 open toward the implant head 4 is formed in the implant 2 along its longitudinal axis L. The recess 7 is designed at least partially for the positive arrangement and / or for the positive engagement of a tool, in particular at least partially as a polygonal profile 8 or as an inner round profile 19, so that the implant 2 can be screwed into the jawbone 6 with the aid of the tool.

[0056] The polygonal profile 8 is particularly evident in the sectional view of Fig. 1b of the first embodiment of the implant 2. However, other embodiments of the implant 2 also have such a polygonal profile 8 or the inner round profile 19. However, the fourth embodiment of the implant shown in Fig. 6a and 6b shows an inner round profile 19. From this, it can be seen that corresponding polygonal profiles or inner round profiles can be provided for the positive arrangement or the positive engagement of a tool.

[0057] The polygonal profile 8 or the inner round profile 19 extends from an end face of the implant 2 formed on the implant head 4 over a certain length along the longitudinal axis L. The polygonal profile 8 is designed as a hexagon socket profile 9 according to Fig. 1b. In contrast, the design of other polygonal profiles, for example an inner square profile, would also be conceivable. The recess 7 could, at least in part, for the positive arrangement and / or for the positive engagement of a tool, instead of the polygonal profile 8, also have a different cross-sectional shape than that of the polygonal profile 8, such as a slot-shaped, cross-shaped or star-shaped cross-sectional shape, in particular, for example, an inner round profile 19, in particular an inner square profile as can be seen in Fig. 6b.

[0058] The recess 7 has at least partially an internal thread 10. With the internal thread 10, a connection and / or fastening and / or arrangement of an additional, further structure 11 of the implant system 1, such as in particular an abutment 11.1, a connector 11.2, a crown 11.3 and / or a temporary prosthesis, with or on the implant 2 can then be realized with the aid of a retaining screw 12.

[0059] Fig. 7 shows a fifth embodiment of the implant system 1, with a fifth embodiment of the implant 2, wherein here the abutment 11.1 is arranged and / or fastened to the implant 2 and / or is effectively connected to the implant 2. The abutment 11.1 is designed here as a straight abutment 11.1 with a cylindrical outer circumference, wherein the longitudinal axis of the abutment 11.1 - in the connected and / or fastened and / or arranged state of the abutment 11.1 with or on the implant 2 - is arranged substantially in the extension of the longitudinal axis L of the implant 2. In contrast, it would also be conceivable for an oblique abutment to be arranged and / or fastened to the implant 2 and / or connected to the implant 2, the longitudinal axis of which abutment is at an angle to the longitudinal axis L of the implant 2.Such an oblique abutment then has a through-hole for the retaining screw, wherein the longitudinal axis of the through-hole is then arranged essentially in the extension of the longitudinal axis L of the implant 2.

[0060] Fig. 8 shows a sixth embodiment of the implant system 1 with the fifth embodiment of the implant 2, but here, in contrast to Fig. 7, a connector 11.2 is arranged and / or fastened and / or connected to the implant 2. With the help of the connector 11.2, in particular a healing cap can be effectively connected to an implant 2 and / or arranged on the implant 2. The connector 11.2 can be effectively connected to the implant 2 with the help of the retaining screw 12. The connector 11.2 has a through-opening. The retaining screw 12 can be arranged for mounting and / or arranging the connector 11.2 on the implant 2 - penetrating the connector 11.2 in the region of the through-opening. The connector 11.2 preferably has a head region for the effective, in particular force-fitting and / or form-fitting, connection of the connector 11.2 to the healing cap and / or for the arrangement of the healing cap on the connector 11.2.Contrary to the illustration in Fig. 8, the connector could also have an implant region for arranging the connector on the implant, wherein the implant region then projects from the connector to the implant into the implant when connected. The connector 11.2 has an external thread, particularly in its head region. The healing cap, not shown here, can then be connected to the external thread of the connector 11.2, particularly by means of an internal thread of the healing cap. Fig. 9 shows a seventh exemplary embodiment of the implant system 1, with a sixth embodiment of the implant 2, with a modified outer contour of the implant head 4 and wherein here a crown 11.3 is arranged on the implant 2 and / or fastened and / or effectively connected to the implant 2. Such a crown 11.3 is preferably glued to the implant head 4 for the most permanent connection possible.

[0061] The fifth, sixth, and seventh embodiments of the implant 2 according to Figures 7, 8, and 9 can each be produced by grinding the implant head 4 from the first embodiment of the implant 2, and then a further component can still be arranged and / or fastened to the implant head 4 and / or connected to the implant head 4, as shown in Figures 7, 8, and 9. This is a further reason why the implant head 4 is designed to be grindable. After grinding, an important function of the implant 2 is still ensured, namely that a connection and / or fastening and / or arrangement of a further structure 11 of the implant system 1, such as in particular the abutment 11.1, the connector 11.2, the crown 11.3, and / or the temporary prosthesis, with or on the implant 2 can be realized.

[0062] The implant 2, namely the implant body 3 and the implant head 4, is designed, in particular, as a one-piece component according to all embodiments shown. The implant 2 comprises or is made of a ceramic material, in particular a zirconium oxide ceramic.

[0063] The implant head 4 has an implant head gingival region 4.1 adjacent to the implant body 3, wherein the implant head gingival region 4.1 is provided and / or designed - in the connected and / or fastened and / or arranged state of the implant body 3 with or on the jawbone 6 - to be at least partially enclosed by a gingiva 13 and / or to be in direct contact with the gingiva 13. This state is illustrated in particular in Fig. 2, wherein the gingiva 13 is shown adjacent to the jawbone 6, in particular above the jawbone 6. The gingival region 4.1 has, in particular, a cylindrical outer circumference. In contrast, the gingival region 4.1 could also have a different outer circumference, e.g., with a changing outer diameter.

[0064] On the side of the implant head gingival region 4.1 facing away from the implant body 3, the implant head 4 has an implant head holding region 4.2 with a substantially constant outer diameter. However, the latter does not apply, in particular, to the embodiment shown in Figs. 6a and 6b. In the embodiment shown in Figs. 6a and 6b, the implant head holding region 4.2 has an outer diameter that decreases along the longitudinal axis L; in particular, the implant head holding region 4.2 is tapered or conical in this case.

[0065] However, the implant head holding area 4.2 has a smaller outer diameter than the implant head gingival area 4.1. The implant head holding area 4.2 also has a cylindrical outer circumference, as shown in Fig. 5 and 7, respectively.

[0066] According to the seventh embodiment of the implant 2 from Fig. 9, the implant head holding region 4.2, on the other hand, has an outer circumference with a changing outer diameter, wherein the outer diameter of the implant head holding region 4.2 then continuously decreases from the implant head gingival region 4.1 to the front side of the implant 2 formed on the implant head 4. Other courses and / or other cross-sectional designs of the implant head holding region are also conceivable; in particular, in a further embodiment, the implant head holding region, in particular its outer region, can also be designed to run conically, in particular a corresponding outer edge can be designed to run conically, as shown, for example, in Figs. 6a and 6b; this should also be noted.

[0067] According to Figures 1 to 8, a bevel 4.3 is formed between the implant head gingival region 4.1 and the implant head holding region 4.2. An edge is formed in the transition between the bevel 4.3 and the implant head gingival region 4.1, as well as in the transition between the bevel 4.3 and the implant head holding region 4.2. It is also conceivable that a stepped transition with several and / or only a single step is formed between the implant head gingival region and the implant head holding region. In particular, only a single step or even just a shoulder can be formed as the transition between the implant head gingival region and the implant head holding region; this should also be noted.

[0068] According to Figures 1a, 2, 3, and 5, a bead-shaped locator section 4.4 with an outer diameter that is larger than the implant head holding section 4.2 is formed on a front end region of the implant head 4 facing away from the implant body 3. With the aid of the bead-shaped locator section 4.4, an additional, further structure 11 of the implant system 1, in particular a temporary prosthesis, can be arranged on the implant 2 and / or connected to the implant 2. The bead of the locator section 4.4, which protrudes relative to the implant head holding section 4.2, is designed, in particular, to be semicircular in cross-section of the implant 2, wherein the bead can then be formed by rotating this semicircular shape around the longitudinal axis L. Instead of the semicircular shape, a different type of protruding contour could also be implemented to form the locator section. In contrast, the figures shown in Figs. 4a and 4b and 6a and6b, an implant 2 without such a bead.

[0069] Furthermore, the following may be carried out:

[0070] The implant head holding region 4.2 and the bevel 4.3 protrude—in the connected and / or fastened and / or arranged state of the implant body 3 with or on the jawbone 6—at least partially, in particular completely, from the gingiva 13, as shown in Fig. 2. The implant head 4 is thus designed to be grindable, in particular, at least up to the implant head gingival region 4.1.

[0071] The implant system 1 has - as shown in Figs. 4a and 4b - at least one ring 14, in particular a metal ring. The ring 14 can be supported and / or arranged on the implant 2, here in Fig. 4a, in the region of the bevel 4.3, so that a part of the implant head 4 protrudes from the ring 14. The then protruding part of the implant head 4 can be ground down to the ring 14 supported on the implant 2 using a grinding tool 15. Such a grinding tool 15 is shown in particular in Figs. 10c and 10e of the method illustrated in Figs. 10a to 10e for individually adapting the implant 2 of the implant system 1. The ring 14 preferably rests against the bevel 4.3 over its entire circumference.It is also conceivable that the ring rests on a step-shaped transition and / or on a shoulder or also on the implant head holding area, in particular in this case being supported and / or mounted accordingly, which will be explained in more detail below.

[0072] According to the first to third embodiments of the implant 2, in particular as shown in Figs. 3, 4a and 5, the implant head 4 has at least one connecting region 4.5, in particular a notch or an elevation, for the positive and / or non-positive arrangement of the ring 14 on the implant 2 and / or for the positive and / or non-positive connection of the ring 14 to the implant 2. The positive and / or non-positive arrangement of the ring 14 on the implant 2 is shown in Fig. 4a, wherein Fig. 4b shows exclusively the ring 14 from Fig. 4a in a plan view. In this case, as shown in Figs. 3, 4a and 4b, the connecting region 4.5 in the embodiment of the implant 2 shown in Figs. 3 and 4a is designed in particular as at least one groove-shaped notch running in the longitudinal direction of the implant 2 or the connecting region 4.5 has this groove-shaped notch, in particular a plurality of groove-shaped notches.Fig. 4b shows corresponding, unspecified elevations on the inner circumference of the ring 14, which then engage in the respective groove-shaped notches of the connecting region 4.5 when the ring 14 is pushed onto the implant head 4. In the respective illustrations shown in Figs. 4a and 4b, the ring 14 shown in Fig. 4b is shown in a position rotated relative to the groove-shaped notches of the connecting region 4.5; this should also be noted. However, the "reverse case" is also conceivable, namely that the connecting region 4.5 has corresponding groove-shaped elevations, in which case the inner circumference of the ring then has corresponding groove-shaped notches.

[0073] The connecting region 4.5 extends in the longitudinal direction of the implant head 4 according to the first and second embodiments of the implant 2 over the entire implant head holding region 4.2 and at least partially over the bevel 4.3, as can be seen in particular from Fig. 3, wherein the connecting region 4.5 is designed here as a notch. Preferably, several, in particular four, connecting regions 4.5 are distributed circumferentially on the implant head 4 or in particular four groove-shaped notches. Correspondingly, the ring 14 has at least one elevation on its inner circumference, preferably several, in particular four, circumferentially distributed elevations, as shown in Fig. 4b. When the ring 14 is arranged on the implant 2 in a form-fitting and / or force-fitting manner, the elevations of the ring 14 engage in the notches of the implant head 4.It would also be conceivable, however, that at least one elevation formed on the implant head engages in at least one notch formed in the ring, although this is not shown in Figs. 3 and 4.

[0074] In particular, in a further developed embodiment, it would also be conceivable for the connecting region 4.5 on the implant head 4 to have corresponding groove-shaped notches which run in the longitudinal direction of the implant 2, as shown in Fig. 3 and 4a, wherein in the region of the bevel these groove-shaped notches are then essentially bent at a 90° angle, partly extended in the circumferential direction, or partly also run circumferentially in the region of the bevel. The ring could then have corresponding elevations, which are button-shaped, for example, in particular only in one end region. This would make it possible to slide the ring onto the implant head, wherein the elevations engage in the groove-shaped notches, the ring can then be pushed onto the implant head until it comes into contact with the bevel, and the ring can then be rotated orThe corresponding elevations could then be screwed into the groove-like notches of the bevel, some of which also extend circumferentially. Ultimately, a ring positioned on the implant head in this way would then also be appropriately positioned or fixed in its axial direction, namely after the elevations have been screwed into the aforementioned groove-like notches, some of which extend circumferentially in the bevel. This possibility of a corresponding embodiment should also be mentioned.

[0075] According to Fig. 5, the connecting region 4.5 is formed in the region of the bevel 4.3 and as a circular notch or elevation. Preferably, several, in particular four, such circular notches or elevations are distributed circumferentially on the bevel 4.3. If an associated ring with at least one, preferably several, in particular four, circular notches or elevations distributed circumferentially on its inner circumference is arranged on the implant 2 in a form-fitting and / or force-fitting manner, each notch engages with an associated corresponding elevation (or vice versa).

[0076] 6a and 6b show a further very preferred embodiment of the implant system 1. In particular, the implant head 4 here has at least one guide region 4.6, in particular four guide regions 4.6 distributed over the circumference. The respective guide region 4.6 is designed in particular as a notch or a groove. The ring, not shown here in Figs. 6a and 6b, has at least one elevation for engaging in the guide region 4.6, in particular four elevations for engaging in four guide regions 4.6. By means of the corresponding elevation or elevations, a targeted forced guidance of the ring along the longitudinal direction L of the implant 2 in the region of the implant head holding region 4.2 is then enabled or realized with the aid of the respective guide region 4.6. In this case, the respective guide region 4.6 extends in the longitudinal direction L of the implant head 4, in particular extends over the entire implant head holding region 4.2.It is also conceivable for the guide region to extend partially over the bevel 4.3, which is still visible in Fig. 6a and 6b. As can be seen in particular from Fig. 6b, the guide region 4.6 has, in particular, four notches and / or grooves, wherein the ring (not shown here) then has, corresponding thereto, a plurality of elevations, in particular four, formed on its inner circumference. It can be clearly seen that the implant head holding region 4.2 has the previously mentioned groove 18, which runs at least partially, in particular completely, around its circumference and / or a groove-shaped notch. The elevation or the respective elevations of the ring (not shown here) can be screwed into the groove 18 for the positive and / or non-positive arrangement of the ring on the implant 2, in particular for its fastening in the axial direction on the implant 2.On the one hand, a targeted forced guidance of the ring along the implant head holding area 4.2 via the guide areas 4.6 is realized, and on the other hand, a securing of the ring in the axial direction is realized, so that it can no longer move along the longitudinal axis L after the respective elevation or elevations of the ring have been screwed into the groove 18.

[0077] The ring 14 has a height or thickness of 0.3 mm to 3 mm, in particular 0.5 mm to 2 mm, in the longitudinal direction. The ring 14 preferably has a substantially constant height across its circumference. It would also be conceivable, however, for the height of the ring to vary radially along its circumference.

[0078] In particular with the aid of Figures 10a to 10e, the method for individually adapting at least one implant 2 of the implant system 1 described above will now be explained in more detail:

[0079] The implant head 4 is at least partially ground down in order to subsequently arrange and / or fasten and / or connect a specific structure 11 and / or a specific further component to the implant 2.

[0080] The grinding is carried out, as shown in Figs. 10c and 10e, by means of a grinding tool 15. The areas of the grinding tool 15 suitable for removing material are symbolized by a dotted pattern and contact the implant head 4 during the grinding process.

[0081] A centering pin 16 of the grinding tool 15 is arranged in the recess 7 of the implant 2 in order to support and / or center the grinding tool 15 on the implant 2 during the grinding of the implant head 4 with the centering pin 16. A longitudinal axis of the grinding tool 15 is thus aligned with the longitudinal axis L of the implant 2, in particular so that the longitudinal axis of the grinding tool 15 and the longitudinal axis L of the implant 2 are essentially congruent. The grinding tool 15 rotates about its longitudinal axis during grinding.

[0082] In addition to the grinding processes illustrated in Figs. 10c and 10e, a further grinding process is performed to produce the implant 2 according to its second embodiment shown in Fig. 10b from the implant 2 according to its first embodiment shown in Fig. 10a, wherein the bead-shaped locator section 4.4 is ground off. At this point, it should be noted that the implant 2 may not have a bead, i.e., the implant 2 shown or illustrated in Figs. 6a and 6b can also be individually adapted using the method described here, i.e., without the need to first grind off a bead.

[0083] To further process the implant 2 according to its second embodiment shown in Fig. 10b, the ring 14 is slipped over the implant head 4 until the ring 14 is supported and / or mounted on the implant 2 in the region of the bevel 4.3, so that a portion of the implant head 4 protrudes from the ring 14, particularly after the bead-shaped locator section 4.4 has been ground down. This situation is illustrated in Fig. 10b.

[0084] As already mentioned above, the implants 2 shown in the embodiments 4a or 4b and 6a or 6b can also be machined accordingly according to the method without having to grind off a bead, since these implants 2 do not have a bead, this should be pointed out again.

[0085] In the method according to the invention, the implant head 4 is at least partially ground down in order to subsequently arrange and / or fasten and / or connect a specific structure 11 and / or a specific further component to the implant 2. A ring 14 is first placed over the implant head 4 and / or over an implant head holding region 4.2 and / or arranged thereon until the ring 14 is supported and / or arranged and / or mounted on the implant 2 such that a portion of the implant head 4 protrudes from the ring 14. Depending on the specific embodiment of the implant 2, the ring 14 can be supported and / or arranged and / or mounted in particular in the region of a bevel 4.3 and / or at a stepped transition and / or at an implant head gingival region 4.1.

[0086] When the ring 14 is slipped over, elevations formed on the inner circumference of the ring 14 are first aligned with the connecting regions 4.5, which are designed here as notches, and in particular the ring 14 is rotated accordingly. The elevations are then engaged with the notches. The ring 14 is subsequently displaced along the longitudinal axis L until the ring 14 is supported and / or mounted on the implant 2 in the region of the bevel 4.3. The latter applies in particular to the embodiments shown in Figs. 1 to 5. In the embodiments of the implant system 1 shown in Figs. 6a and 6b, the ring, with the elevations formed on its inner circumference, enters the guide regions 4.6, is displaced along the longitudinal axis L, in particular over the implant head holding region 4.2, and is guided along the guide regions 4.6 in the direction of the groove 18 and then, at the end of the guide regions 4.6, is screwed with its elevations into the groove 18.

[0087] It is therefore also conceivable that the method is not started with the implant 2 according to its first embodiment from Fig. 10a, but with the implant 2 according to its second embodiment from Fig. 10b or 4a or according to its embodiments from Fig. 5 or Fig. 6. If the connecting region 4.5 according to the third embodiment of the implant 2 from Fig. 5 is circular, the alignment of the equally circular elevations or notches then formed on the inner circumference of the ring to the connecting regions 4.5 during the displacement of the ring along the longitudinal axis L can only take place shortly before contact or with contact with the bevel 4.3.

[0088] The part of the implant head 4 protruding from the ring 14 as shown in Fig. 10b and 10c is ground down to the ring 14 supported on the implant 2 using a face grinding tool 15.1, as shown in Fig. 10c, forming a plateau 17. In the situation shown in Fig. 10c, the grinding process is almost complete; the part of the implant head 4 protruding from the ring 14 is now very small. The area of ​​the face grinding tool 15.1 suitable for removal is preferably annular on one end side of the face grinding tool 15.1. The area of ​​the face grinding tool 15.1 suitable for removal is thus arranged in a plane perpendicular to the longitudinal axis of the face grinding tool 15.1. The grinding process is terminated, in particular, when the face grinding tool 15.1 contacts the ring 14.

[0089] After the grinding process has been completed, i.e. after the creation of the plateau 17, the ring 14 is removed from the implant 2. This removal takes place between the embodiments of the implant system 1 shown in Fig. 10c and 10d. Fig. 10d shows the fifth embodiment of the implant 2, which is, for example, part of the fifth or sixth embodiment of the implant system 1 from Fig. 7 and 8. The plateau 17 is shown in particular in Fig. 10d. The plateau 17 forms the front side of the implant head 4. The plateau 17 lies in a plane running perpendicular to the longitudinal axis L. The plateau could, on the other hand, also run in a plane at an angle to the longitudinal axis L, in which case, however, the associated grinding process must be carried out differently than previously described.

[0090] As shown in Fig. 10e, the implant head 4 is ground on its outer circumference with the aid of a circumferential grinding tool 15.2, in particular one having a specific inner contour, to produce a specific outer contour. Thus, the seventh embodiment of the implant 2 according to Fig. 10e or Fig. 9 can be produced from the fifth or sixth embodiment of the implant 2 according to Fig. 10d. According to the situation shown in Fig. 10e, the grinding process itself has already been completed, the desired, specific outer contour has therefore already been achieved, and all that remains is to remove the circumferential grinding tool 15.2 from the implant 2. The specific inner contour of the circumferential grinding tool 15.2 is arcuate and rotationally symmetrical to the longitudinal axis of the circumferential grinding tool 15.2, which rotates about its longitudinal axis during the grinding process.

[0091] The specific structure 11 and / or the further specific component is designed as an abutment 11.1, a connector 11.2, a crown 11.3, and / or a temporary prosthesis. It is conceivable that the method described above is interrupted, for example, to arrange and / or fasten an abutment 11.1, a connector 11.2, or a temporary prosthesis on the implant head 4 for a specific period of time and / or to connect it to the implant head 4.

[0092] This is particularly important when the procedure is performed with the implant body 3 connected and / or secured and / or arranged to or on the jawbone 6, in particular in the patient's oral cavity. Then, by means of the specific structure 11 and / or the further specific component, a healing process of the jawbone 6 and / or the gingiva 13 can be positively influenced.

[0093] Alternatively, the procedure is performed outside the patient's oral cavity. It is also conceivable to perform parts of the procedure, e.g., up to the situation shown in Fig. 9d, outside the patient's oral cavity and to perform further procedural steps, such as grinding the outer circumference of the implant head 4 while the implant body 3 is connected and / or secured and / or arranged to or on the jawbone 6.
