Abstract:
A kit of dental implant materials for bone augmentation and bone defect reparation comprising: (a) an implant body; and (b) an osseo-stimulative surface, applied to said implant body, said surface including a calcium sulfate (â€œCSâ€ ) compound which is a member selected from the group consisting of CS dihydrate, CS hemihydrate, anhydrous CS and mixtures thereof; and (c) a standalone quantity CS compound for in situ application to said implant body, in which said CS compound is a member selected from the group consisting of CS dihydrate, CS hemihydrate, anhydrous CS and mixtures thereof;wherein said surface comprises a matrix including particles of a resorbable agent for aiding in situ bio-resorption of said CS compound at a rate matching with the healing process of the adjacent osseous tissue in order to inhibit soft tissue filling of the defect and to induce proper bone repair; said resorbable agent being a member selected from the group consisting of aliphatic polyesters of an alpha-hydroxy acid derivative, a hydrophilic polymer, an amino derived polymer, poly-vinyl alcohols, polylactides, polyglycolides, polydioxanides, poly-episilon-caprolactones, polymeric salicylates and mixtures thereof.
