영문 초록

This literatural study about clinical use of Hydroxyapatite (HA) ceramics was done to evaluate HA as a synthetic bone substitue and to introduce the clinical application fields and methods of HA implants to dental practitioners. A number of animal and human experimental and clinical studies for the clinical use of HA have been made by many authors for last several decades. HA has been shown to be a safe, effective, and convinient implant material as a synthetic bone substitute. HA has been applied with marked success in the clilical application fields as follows; 1) ridge reconstruction in alveolar ridge deficiency (ridge augmentation). 2) repairing periodontal lesion. 3) post-extraction preservation of the alveolar ridge (ridge maintenance). 4) using in oral & maxillofacial surgery (orthognathic and reconstructive surgery) a. obliteration of cystic cavity. b. alveolar ridge defect and cleft grafting. c. filling of bone defect in mandibular & facial bone osteotomy. d. facial bone augmentation. e. reconstruction of mandibular continuity. f. Additional use for metallic implant application. g. etc. HA particles are viewed to offer the possibility of providing better prosthᄋdontic care to a large range of patient than could be satisfactorily treated with conventional prosthodontic techniques.in the patients with deficient alveolar ridge. HA particles have been shown to definite potential as an alloplastic implants in the treatment of periodontal osseous defect. HA tooth roots and HA particles have been shown to provide long lasting support to the surrounding alveolar bone and delay its post-extraction resorption and are viewed as a valuable and practical tool of preventive prosthodontics. HA blocks and particles are viewed to be a promising material as a bone substitute and marrow extender in the treatment of maxillary & mandibular defects, cysts, tumors, osteomyelitises， and clefts，and as a spacer and bo ne substitute for bone graft to providing stability and diminish postoperative relapse in osteotomy for orthognathic and reconstructive surgery.
