First Claim
Patent Images
1. A method for restoration of dental tissue, and providing an implant device for attaching artificial teeth comprising the steps of:
- (i) preserving and dressing the cavity created by the extraction of a tooth;
(ii) estimating or measuring the parameters of the cavity or lesion formed within the bone and gum tissues;
(iii) providing a stent assembly comprising an expandable stent made from a shape-memory material, said stent having a sleeve of porous fabric at least partially covering said stent, said stent assembly generally conforming to the parameters of said cavity or lesion;
(iv) positioning the said stent assembly within the cavity or lesion; and
(v) delivering an in situ polymerizable, exothermic polymer system to the inner space of the said assembly to provide internal structure to the assembly.

Abstract
The present invention relates generally to surgical implants intended for the augmentation, repair, and restoration of soft tissue (e.g. gingiva or cartilage), hard tissue (e.g. bone), and the like. More particularly, the present invention relates to the in vivo anchoring of cast implants by stent-like anchors made of a shape memory alloy and/or polymers which are desirably covered with a textile sleeve of a specific porosity.

- 26. A dental implant device comprising a generally elongate expandable stent member at least partially covered by a porous sleeve formed from a porous polymeric fabric or film, said stent member being formed from a shape memory material capable of expanding in the cavity of the implant site, said sleeve being adapted to receive a polymerizable material therein for providing internal structure and support to said implant device upon in situ cure.

31. A dental implant kit comprising (i) a stent member;
- (ii) a sleeve member for covering said stent member and for receiving in situ polymerizable polymer and (iii) polymer components which when mixed can be delivered in vivo for in situ polymerization.
