다양한 골 이식재를 이용한 골유도재생술의 골 치유에 관한 비교 연구:

THE COMPARATIVE STUDY OF GUIDED BONE REGENERATION USING VARIOUS OF BONE GRAFT MATERIALS

The purpose of this study is to evaluate the superficial bony healing after guided bony regeneration using a various bone grafts. Four types of bone grafts were performed by one oral and maxillofacial surgeon to restore the defects around endosseous implants. Group 1 included the allografts using Regenaform. Group 2 included the autograft. Group 3 included the combined grafts using with autogenous symphysis bone and xenograft(BioOss). Group 4 included the xenograft(BioOss). After some heling period, superficial bone biopsy was performed with the surgical blade(#15) during the second surgery. Histologic and histomorphmetric examination were carried out by one pathologist. There was the most new bone formation in the group 3, next group 2. However, there were no statistically significant differences. All group except for group 4 showed favorable bone formation and remodeling.
