Use of Block Hydroxyapitite Implants in The Augmentation of Subalveolar Ridge

Alveolar ridge atrophy develops as a result of many conditions ranging from old age to denture pressures. It is important to realize that its incidence is on the rise and is expected to maintain this trend since better care and economical developments are leading to prolongation of life in all countries. Among the procedures to restore alveolar ridge athrophy we preferred and tried hydroxyapatite implantation in 13 cases. It is observed that hydroxyapatite implantation produces a stronger adherance to the underlying bone with frequent bone growth oven the block. Toxic or inflammatory development and post implantation resorption of the underlying bone, on the other are observed much less frequently in this method compared to others.
