DOUBLE DENTAL IMPLANT THAT REMAINS STABLE IN THE PRESENCE OF PERIIMPLANTITIS

Abstract

An implant formed by two implants: an upper implant and a lower implant, the upper implant being removable. The implant differs from conventional implants in that the body of the implant has a second polished collar corresponding with the beginning of the lower implant. The two implants are connected by a screw located in the lower part of the upper implant of which it forms a part, the screw engaging with the thread of the lower implant. The connection between the two implants is circular, as it must allow anticlockwise rotation when removed.

Claims

1. Stable double dental implant against peri-implantitis, comprising of an implant made up of two implants: an upper implant and a lower implant, so that the upper implant can be removed.

2. Stable double dental implant against peri-implantitis, according to claim 1, characterised in that the double implant differs externally from a classic implant in having a second polished band in the body of the implant, which corresponds to the start of the lower implant.

3. Stable double dental implant against peri-implantitis, according to claim 1, characterised in that the connection between the two implants is by means of a screw located in the lower part of the upper implant and of which it forms part, staying in the thread of the lower implant.

4. Stable double dental implant against peri-implantitis, according to claim 1, characterised by the circular connection between both allowing for counter-clockwise rotation when removed.

DESCRIPTION OF PREFERENTIAL IMPLEMENTATION

[0045] A preferred implementation of the stable double dental implant against peri-implantitis subject of the present invention, with reference to the numerical references, can be based on an implant consisting of two implants: upper implant (1) and lower implant (2), with the ability to remove the upper implant (1).

[0046] Regarding morphology and connection, it comprises those of the classic implant: cylindrical morphology, in self-tapping turns (3) with narrower apex, connected to a 2.70 mm external hexagon (4), 0.70 mm in height (5) and a 4.10 mm linking platform (6). The diameter of the implant (1, 2) is 4.10 mm and the height 11.5 mm.

[0047] The double implant (1, 2) only differs externally from the classic implant in having a second polished band (7) in the body of the implant (1, 2), which corresponds to the start of the lower implant (2).

[0048] The connection between the two implants (1, 2) is by means of a screw (8) that is located in the lower part of the upper implant (1) and of which it forms part, staying in the thread (9) of the lower implant (2).

[0049] The connection between both (1, 2) is circular, since it has to allow for counter-clockwise rotation when it is removed.
