Definitions
- the present invention relates to a dental implant with male frustoconical connector.
- the present invention relates more particularly to connection means between the anchor base of the implant and the support pillar of the prosthetic tooth.
- implant bases which comprise specific means of connection to a support pillar.
- EP 0 075 525 discloses a dental implant comprising a neck, provided with an annular groove, which is extended upwards by a tenon for connection to a prosthetic tooth (false chin).
- these implants are the seat of infections that usually occur at the interface between the implantation bone area and the gingiva.
- the present invention intends to remedy this first technical problem by deporting the prosthetic connection above this area and strengthening the tightness of the assembly between the post and the pillar so as to prevent the proliferation of germs.
- the present invention also aims to solve this technical problem by modifying the profile of the implant in the parts located at the burial limit of the base.
- the known implants do not make it possible to obtain a rapid cicatrization of the gingiva in the implantation zone, nor a satisfactory stability of the gingival tissue.
- the invention therefore also aims to optimize the profile of the neck defining the space where the reconstruction of the gingiva occurs so as to ensure better contact between the scar tissue and the implant.
- the implant of the present invention is characterized in that said pin which has a frustoconical profile, is intended to be sealed in a sealed manner by a homothetic bore formed in said pillar and carries a indexing relief suceptible to cooperate with a complementary imprint made in the bore of said pillar to ensure its angular positioning.
- said groove has a curvature determined by at least two distinct radii so as to optimize the space required for gingival reconstruction.
- the minimum diameter of said neck is located at half height.
- the outer end of the base is provided with a curvilinear peripheral edge of about 1 mm radius, providing the connection with the base of said neck.
- the base of said pillar is frustoconical.
- said indexing relief consists of an equilateral triangular section stud inscribed in the upper face of the tenon.
- said tenon is provided with a threaded axial conduit whose lower end is located substantially halfway up the neck and which is intended to receive a screw passing through the bore.
- the minimum diameter of the neck is 2.7 mm and its height of 1.5 mm.
- the upper diameter of the tenon is 3.5 mm.
- the two radii of curvature of the neck are respectively between 0.5 and 2.5 mm.
- the implant of the invention considerably reduces the risk of bacterial infection by virtue of the increased strength and tightness of the cone-on-cone assembly between the base and the abutment.
- the specific profile of the connecting neck is particularly atraumatic and accelerates the gingival healing phenomena.
- Another advantage lies in the specific profile of the indexing means.
- FIGS. 1A and 1B show exploded perspective views of an embodiment of the implant of the invention
- Figure 2 shows a partial view of the implant base of Figure 1
- Figure 3 shows a top view of the base of Figure 2
- FIG. 4 represents a view in partial section along IV-IV of the base of FIG.
- the implant according to the invention as illustrated in Figures 1A and 1B comprises a threaded base 1 for intraosseous anchoring.
- the base 1 is provided, at its outer end 1a, connecting means to a pillar 2 for supporting a prosthetic tooth (not shown).
- connection means comprise a neck 11, provided with an annular groove 10, which is extended upwards by a stud 12.
- the pin 12 which has a tapered profile tapering upwards, is intended to be sealed in a sealed manner by a homothetic bore 20 formed in the base 21 of the pillar 2.
- the pin 12 carries an indexing relief 13 likely to cooperate with a complementary cavity (not shown in the figures) made in the bottom of the bore 20 of the pillar 2 to ensure its angular positioning.
- the groove 10 has a curvature which is determined by at least two distinct radii R1, R2 so as to optimize the space required for the gingival reconstruction.
- the minimum diameter of the neck 11 is located substantially at mid-height.
- the end 1a of the base 1 which remains outside the bone tissue is provided with a curvilinear peripheral edge whose radius RO is about 1 mm, providing the connection with the base of the neck 11 and providing continuity in profile with the curvature of radius R1 of the groove 10 (see Figure 2).
- the indexing relief here consists of a pad 13 of equilateral triangular section inscribed in the upper face of the pin 12.
- the vertices of the triangular stud 13 are rounded to facilitate the mounting of the pillar 2.
- the tenon 12 is provided with a threaded axial duct 14 whose lower end is located substantially halfway up the neck 11 and which is intended to receive a screw 3 to lock the pillar 2 on the base 1.
- the screw 3 is housed in a well 22 communicating with the bore 20 and through the complementary cavity of the indexing relief 13 of the post 12.
- the base 21 of the pillar 2 is also frustoconical but its cone is inverted compared to that which forms the post 12.
- connection is thus perfectly sealed and prevents any penetration of organic particles likely to create bacteriological pollution.
- the base 1 is preferably anchored by screwing into the bone tissue. Where appropriate, the upper part of the base will be provided with drive means such as peripheral notches for gripping by a clamping tool.
- the lateral face of the post 12 ensures the translation of the base 21 and a complementary rotation ensures, at the end of assembly, the mutual commitment of the footprint and the relief indexing.
- the cooperation of the relief 13 and the footprint also provides anti-rotation locking of the prosthetic tooth.
- the occluded air can escape to the outside through the well 22.
- the minimum diameter of the neck 11 is 2.7 mm and its height is 1.5 mm
- the upper diameter of the post 12 is 3.5 mm
- the two radii of curvature (R1, R2) of the neck 11 are respectively between 0.5 and 2.5 mm.
- the angle of the cone of the pin 12 and the cavity 20 is between 4 ° and 6 °.
