Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows a top piece, according to the current state of technology as indicated in FIG. 1;

(2) FIGS. 2a and 2b illustrate an embodiment of the dental implant according to the invention;

(3) FIG. 3 shows a second embodiment of the dental implant according to the invention; and

(4) FIGS. 4a and 4b are plan views of the dental implants shown in FIGS. 1 and 3, respectively.

DETAILED DESCRIPTION OF THE INVENTION

(5) FIG. 1 displays an example of a top piece 1 (with platform switching) according to the state of the technology, in a section displaying the middle longitudinal axis of the arrangement.

(6) The top piece 1 features a platform 3 with a first platform surface 4 and a platform surface 5. The platform 3 features a diameter D. On the first surface of the platform 4, there is a retention pin 8 (with an anti-rotation lock 14) for the mounting of the mesostructure 9. A connecting pin 6 is located on the second platform surface 5.

(7) The corresponding pin-shaped dental implant 2 features a blind bore 7, whose dimensioning is adapted to the connecting pin 6. The platform 3 is formed with a smaller diameter in the area of the implant shoulder 10, as a pin-shaped dental implant 2 (platform switching). In the view from above, the second surface of the platform 5 is flush with the pin-shaped dental implant, and its diameter D is thus selected at the same size as the diameter D of the pin-shaped dental implant 2. The distance between the adhesive joint 11 and the pin-shaped dental implant 2 is very small, which can lead to a bacterial infestation of the pin-shaped dental implant 2. Additionally, the second platform surface 4 only features a small surface for the desired accumulation of cells.

(8) FIGS. 2a and 2b show a first execution example of the invention, in a section oriented on the middle of the longitudinal axis of the arrangement.

(9) The top piece 1 features a platform 3 with a first platform surface 4 and a second platform surface 5. The platform 3 is formed with a circular circumference in the area of the first and second platform surfaces 4, 5 and features a diameter D. The first platform surface 4 features a retention pin 8 for the mounting of the mesostructure 9. The second platform surface 5 features a connecting pin 6. The first platform surface is formed around the retention pin 8 as a setting shoulder 12 (circular, around the retention pin 8) for the mesostructure 9. As is well known, the top piece 1 can feature an axially arranged borehole, which extends to the connecting pin 6 and which allows the screwing of the top piece 1 onto the pin-shaped dental implant 2, by means of a screw 13. The connecting pin 6 and the blind bore 7 can feature, at least for certain parts of their lengths, the corresponding threads.

(10) The corresponding pin-shaped dental implant 2 features a blind bore 7, whose dimensioning is adapted to the connecting pin 6. In the area of the implant shoulder 10, the platform 3 is formed with a smaller diameter as the pin-shaped dental implant 2 (platform switching). In a view from above on the second platform surface 5, platform 3 features a larger diameter D, than the pin-shaped dental implant 2 in the area of the implant shoulder 10 (diameter D), thus platform 3 protrudes over the corresponding pin-shaped dental implant 2. The adhesive joint 11 is protected by platform 3 from the pin-shaped dental implant 2. A bacterial infestation of the pin-shaped dental implant 2 is thus made more difficult, if not avoided altogether. The second platform surface 5 features a larger surface for the desired settlement of cells.

(11) FIG. 2b indicates in a detailed view the platform 3 and the second platform surface 5 near the end of the connecting pin 6 (the retention pin 8 is not displayed). The ratio between the diameter D and the pin diameter d is shown.

(12) FIG. 3 indicates a second execution example of the invention, in a section indicating the middle longitudinal axis.

(13) The execution example of FIG. 3 is different from the one in FIG. 2 only by the fact that the edge of the platform 3 is arched in a coronal direction, away from the connecting pin 6, which results in a plate-like formation of the first platform surface 4 (over the entire angular range 1, 2, 3, 4). Additionally, the platform 3 is tapered in the direction of its edge (the thickness of the platform 3, generated by the distance between the first and second platform surfaces 4, 5 is smaller than in the center of the platform 3). The thickness of the platform 3, before the area where it starts tapering, can be, for example, 0.8 millimeters.

(14) These two measures (bulging and tapering) can also be applied individually, which means independently from each other. The bulging can also take place independently from the diameter of the platform.

(15) Otherwise, the top piece 1 is formed exactly as in the representation in FIG. 2. For reasons of clarity, not all the details represented in FIG. 2 are represented again in FIG. 3.

(16) Unlike the representation in FIGS. 2 and 3, there is also the possibility of using top pieces 1 without platform switching, according to the invention. In this case, the second platform 5 would connect directly (without the tapered part in the direction of the connecting pin 6) to the connecting pin 6 and be supported by the implant shoulder 10 or at least indicate only a minimal distance to it.

(17) FIGS. 4a and 4b indicate a top piece 1 according to FIG. 1 or FIG. 3 in a view from above onto the second level of the platform 5, while different anatomical adaptations were performed on the platform 3, bearing in mind the dimensions of the patient's teeth, adjoining the mesostructure to be mounted onto the platform 3.

(18) The corresponding hatched areas of the platform 3 are removed by removing the material. Before removing the material, the platforms 3 are formed in a view from above onto the first or second platform surface 4, 5, preferably with a circular circumference.

(19) Thus, there are platforms 3, for which the diameter D of the platform 3 is only large enough over a part of 1, 2 of the total angular area 1, 2, 3, 4 (1+2+3+4=360), that a top piece 1, connected with a corresponding pin-shaped dental implant 2, and the platform 3 will protrude in a view from above onto the platform surface 5 over the corresponding pin-shaped dental implant 2. In the areas 3, 4 of the total angular area 1, 2, 3, 4, the platform 3 is flush, in a view from above onto the second platform surface 5, with the pin-shaped dental implant 2.

(20) In contrast to the representation, the retention pin 8 must not necessarily create a right angle with the first platform surface 4.

(21) The material removal could also be selected in such a way, that the diameter D of the platform 3, remains large enough over the total angular area 1, 2, 3, 4, that the top piece 1, connected to the corresponding pin-shaped dental implant 2, will protrude in a view from above onto the second platform surface 5, over the corresponding pin-shaped dental implant 2, but at a different width, according to the angular area.
