Abstract
In this study, histologic behaviour of collagen coated hidroxylapatite particles implanted in human periodontal osseous defects has been analized. This material was surgically implanted in four patients, and reentry and block biopsies were carried out 4 and 6 months later.The histologic results demonstrate that this material is well tolerated by sorrounding tissues, not eliciting an inflammatory reaction. At four months, the hydroxylapatite particles appear encapsulated by a very cellular connective tissue and at 6 months are found in direct contact with osteoid and mature bone. This material acts as a filler material, being fully biocompatible and estimulating an osseoconductive reaction of the adyacent alveolar bone.
