Histological evaluation of hydroxiapatite implants in human alveolar bone defect: A case report

Abstract

In Dentistry, the hydroxapatite has been researched and applied for treatment modalities that evolve alveolar bone loss, in dentolousandedentolo usareas. Hydroxiapatite particles were used for the correction of bone sequel after extraction of the upper right central incisor. The boned efect of the buccal face of the lateral incisor was filled, too. Sixteen months later, this tooth was extracted because ofarootfracture. Macroscopic examination showed fixed HAparticles on root‘s surface, rounded by soft tissue. The histological findings did not showed evidence of rejection or expulsion of implant particles.These were found completely encapsulated by connective tissue, keeping aparallel orientation of human periodontal fibers. Cementary reaction was observed in some areas, too.
