[Hydroxyapatite in orthognathic surgery. Animal experimentation and clinical applications]

Abstract

Bone cell conduction can occur within hydroxyapatite, a biocompatible, bioactive, synthetised ceramic material, when it is placed in contact with bone tissue. Results of experimental and clinical studies on maxillary osteotomy incisional lines have confirmed these properties, the quality and stability of the results and the good tolerance of this biomaterial making it a product of choice as a substitute of iliac bone grafts, when no longer indicated in this context.
