Abstract

The buccal implant is constituted by at least one plate of small thickness formed of material containing solubilizable substances. The plate is fastened to the teeth and maintained in close proximity to the gum in order to pass the solubilizable substances into the saliva.

Claims

1. A buccal implant for passing solubilizable substances contained in said implant into the saliva by maintaining part of the implant close to the gum, wherein said implant is constituted by at least one plate of small thickness formed of material containing solubilizable substances and by means for fastening the plate to the teeth, said means being intended to maintain said plate in the vicinity of the gum.

2. A buccal implant according to claim 1, wherein the means for fastening the plate are constituted by at least one needle-shaped spike placed at right angles to the plate and rigidly fixed thereto, said spike being slightly smaller in section than the interdental space and slightly greater in length than the thickness of a tooth at the base thereof.

3. A buccal implant according to claim 2, wherein the transverse section of the spike is polygonal and especially triangular.

4. A buccal implant according to claim 3, wherein the free extremity of the spike remote from the extremity which is integral with the plate is provided with a small flexible stud substantially at right angles to said spike.

5. A buccal implant according to claim 4, wherein said implant is made up of two removable portions consisting of the spike and the plate, said spike being rigidly fixed to a small cross-bar provided with a plurality of male studs and the plate or plates being provided with holes having dimensions and positions corresponding to the studs of said cross-bar.

6. A buccal implant according to claim 5, wherein the plates have a corrugated surface.

7. A buccal implant according to claim 5, wherein both surfaces of the cross-bar are corrugated.

8. A buccal implant according to claim 1, wherein said implant comprises a suction cup rigidly fixed to the plate.

9. A buccal implant according to claim 1, wherein said implant comprises a reinforced wire of smaller section than the interdental space and securely fixed to the plate.

10. A buccal implant according to claim 9, wherein the plate or plates are constituted by a plastic hydrophobic substrate containing hydrophilic inclusions in which the soluble substances are stored.

11. A buccal implant according to claim 10, wherein the plate or plates are provided with a cavity filled with product, the walls of said cavity being constituted by a substance having controlled permeability.
