Many alloplastic materials have been used as the bony substitute in large bony defects caused by fracture, periodontitis, & cyst, etc. Nowadays Hydroxyapatite(HAP) is the most usable material as the bony substitute. The reasonable properties of HAP are nontoxic, biocompatible to host tissues & have osteoconductivity. Other bioceramic materials are recommended as the bony substitute with high success rate. We have studied the clinical use of HAP as the bony substitute in the defected area caused by cyst. The reasonalbe & successful results are obtained. The results were as followed. 1. Better prognosis was obtained in the case of HAP & bone mixed graft than HAP graft only. And the best prognosis was obtained in the case of iliac bone graft. 2. Better prognosis was obtained in Mx. than in Mn. 3. It seems that the soft tissue ingrowth into the HAP granule play an importnat role in the success of the HAP graft. 4. Though the flap covering the HAP granules was perforated, the relative good prognosis was obtained by re - suturing the perforeated site.
