下顎部骨移植に関する臨床的研究 ＩＸ 良性腫よう切除後の下顎骨欠損に対する修復・再建

Abstract

Tumor resections through mandibular preservation as far as possible were carried out for 6 benign tumors composed of 3 ameloblastomas, 2 myxomas and 1 cementifying fibroma. Grafts of 1 particulate cancellous bone and marrow (PCBM), 4 bone chips and 1 block bone taken from the iliac bone without the crest were used for repair or reconstruction of the various types of the defects. All patients were in good clinical courses without postoperative infection. In this paper the results of above bone grafts for mandibular defects which clinically were observed during the past 3 to 6 years were discussed.
