DENTAL IMPLANT WITH FOLDABLE FINS

Abstract

The present invention relates to a dental implant having an anchoring system consisting of foldable fins actuated by an insertion screw; the dental implant is characterised by the following components: an implant body that comprises an implant-abutment connection zone, an externally threaded zone, at least one pair of exit openings and an internally threaded zone; an anchoring means comprising at least one pair of foldable fins and a top opening; an insertion screw comprising a head with an internal hexagonal socket, a stem and a screw thread; when the insertion screw is screwed into the top opening of the anchoring means, it pushes the anchoring means down into the implant body and causes the foldable fins to extend outwards through the exit openings.

Claims

1. A dental implant (1) with foldable fins (8), characterised in that it comprises the following components: a) an implant body (2) that comprises an implant-abutment connection zone (3), an externally threaded zone (4), at least one pair of exit openings (5) and an internally threaded zone (6), b) an anchoring means (7) comprising at least one pair of foldable fins (8) and a top opening (9), c) an insertion screw (10) comprising a head (11) with an internal hexagonal socket, a stem (12) and a screw thread (13), when the insertion screw (10) is screwed into the top opening (9) of the anchoring means (7), it pushes the anchoring means (7) down into the implant body (2) and causes the foldable fins (8) to extend outwards through the exit openings (5).

2. The dental implant (1) with foldable fins (8) according to claim 1, characterised in that there is a trabecular-shaped porous structure (14) in the externally threaded zone (4).

PREFERRED EMBODIMENT OF THE INVENTION

[0031] According to an embodiment of the present invention, FIGS. 1-4 show the dental implant (1) object of the present invention through the main components forming same. Namely, the dental implant (1) with foldable fins (8) is characterised in that it comprises the following components: [0032] a) an implant body (2) that comprises an implant-abutment connection zone (3), an externally threaded zone (4), at least one pair of exit openings (5) and an internally threaded zone (6), [0033] b) an anchoring means (7) comprising at least one pair of foldable fins (8) and a top opening (9), [0034] c) an insertion screw (10) comprising a head (11) with an internal hexagonal socket, a stem (12) and a screw thread (13), [0035] when the insertion screw (10) is screwed into the top opening (9) of the anchoring means (7), it pushes the anchoring means (7) down into the implant body (2) and causes the foldable fins (8) to extend outwards through the exit openings (5).

[0036] As shown in FIG. 2, the dental implant (1) has a porous structure (14) in the mid-high zone of the implant. Namely, there is a trabecular-shaped porous structure (14) in the externally threaded zone (4). Specifically, said porous structure (14) is located in the spaces between the screw threads of the externally threaded zone (4). This porous structure (14) located in the mid-high zone of the implant facilitates the osseointegration process of said dental implant (1). Additionally, it can be seen that the implant body (2) has a self-tapping screw thread (15) at its bottom end.

[0037] FIG. 3 depicts a top view of the implant body, in which the implant-abutment connection zone (3) and the internally threaded zone (6) can be seen.

[0038] FIG. 4 depicts a schematic view corresponding to a cross-section of the body of the dental implant (1). A pair of exit openings (5), an externally threaded zone (4) and an internally threaded zone (6) can be seen in said figure. The externally threaded zone (4) is a double screw thread.

[0039] It can be seen in FIG. 5A how the insertion screw (10) is screwed into the top opening (9) of the anchoring means (7), before carrying out the assembly of the dental implant (1).

[0040] When the screwing operation is performed, the anchoring means (7) is forced down into the implant body (2) by the downward pushing action exerted by the insertion screw (10), so the foldable fins (8) exit through the exit openings (5) towards the cortical zone of the mandible or maxilla, where they will be anchored. The arrangement adopted by the different components of the dental implant (1) after said screwing operation is depicted in FIG. 5B.
