Abstract

PURPOSE
The purpose of this study is to investigate on the regenerative capacity by using different size of graft materials around bony defect around implant. MATERIAL AND METHODS: Dental implant fixtures(Bio-TIS, Korea) were placed into the tibia of 8 rabbits. After placement of implant, artificial defects were created for each group, and the size of bone graft materials were used according to each designated group. 4 weeks after surgery, 8 rabbits were sacrificed. The histologic and histomorphometrical study were done for comparison of the regenerative capacity using 80-90micrometer and 200~1000micrometer size of grafting materials of OCS-B(R). RESULT: Matured bone formation was significantly increased more in Group E1(80-90micrometer) than in Group E2(200~1000micrometer). Group E1(80-90micrometer) showed more significant augmentation in marginal length of graft material per unit area than Group E2(200~1000micrometer). Group E1(80-90micrometer) showed more interspace in graft material than Group E2(200~1000micrometer). Control group showed no new bone formation around and inside of implanted fixture.
CONCLUSION
Small grafting material size has great influence on bone regeneration.
