Experimental ridge augmentation with porous hydroxyapatite implants.

A new hydroxyapatite ceramic implant material for restoration of atrophic edentulous ridges was tested in a canine animal model. The structure of this material is unique, in that it is produced from the skeleton of a coral, and in that it is penetrated by a uniform network of interconnected pores. Results indicate that bone penetrates its structure to a greater degree than had been observed with similar implants constructed of different materials. Implant insertion through a simple surgical technique involving minimal morbidity is a viable method of placement.

Extraskeletal implantation of a porous hydroxyapatite ceramic.

Coralline replamineform hydroxyapatite implants were placed in canine subcutaneous tissues in an attempt to clarify whether the hydroxyapatite matrix acted as a passive matrix for osseous ingrowth when placed in some inherent bone induction capacity. The implants were well-tolerated and elicited no deleterious host response. Connective tissue rapidly infiltrated the pores, but no evidence of bone formation was noted in any of the specimens. It was concluded that this implant material does not act to induce bone formation.
