This study was performed to evaluate bone formation in the calvaria of rabbit by the concept of guided bone regeneration with titanium mesh membrane and demineralized freeze-dried bone. The animal was sacrificed at 2 weeks, 4 weeks, 8 weeks, and 12 weeks after the surgery. Non-decalcified specimens were processed for histologic analysis. 1. The titanium mesh but the biocompatibility was excellent the cell-occlusiveness was feeble. 2. The cell-occlusiveness was feeble and also the soft tissue growth of the upper part of the newly-formed bone after operating was excellent in early stage. 3. The maintenance ability of the space for the GBR very was excellent. 4. The titanium mesh the tissue-integration was superior the wound fixation ability excellent. 5. The demineralized freeze-dried bone did not promote the bone regeneration. 6. With the lapse of time, formation quantity of the bone some it increased, it increased quantity very it was feeble. Within the above results, the titanium mesh for the guided bone regeneration was excellent, the dεmineralized freeze-dried bone confirmed does not promote bone regeneration.

Purpose: The purpose of this study was to evaluate the effectiveness of a novel bone grafting material using an autogeneous tooth (AutoBT) and provide the basis for its clinical application. The AutoBT contains organic and inorganic mineral components and is prepared from autogenous grafting material, thus eliminating the risk of immune reactions that may lead to its rejection. AutoBT can be used as bone material as is has both osteoinduction and osteoconduction activities at guided bone regeneration for implant placement and maxillary sinus graft. Methods: In a total of 63 patients, guided bone regeneration surgery was performed at the time of implant placement, and tissue samples were harvested at the time of the second surgery with the patient's consent. Results: There were no complications in guided bone regeneration using autogeneous tooth. Conclusion: We concluded that AutoBT underwent gradual resorption and was replaced by new bone of excellent quality via osteoinduction and osteoconduction.

Using the rat's skull, the study on the biodegradability and guided bone regeneration of the chitosan membrane was performed. The results are as follows: 1. The biodegradability of the chitosan membrane could not be confirmed, but after 12 weeks, this membrane did not yet break into small pieces and there was no specific local tissue reaction. 2. It was not certain whether the pore size of this membrane was affected on osteoblastic activity. 3. After 6 weeks, the bony defect area of rat's skull was not completely filled, but on high magnification it showed that the osteoclasts and the osteoblasts were observed in the regenerating area. In conclusion, the chitosan membrane developed in this study was fit for guided bone regeneration.

Silk fibroin membrane was prepared and examined to know the feasibility of SF membrane as guided bone regeneration. The morphology of silk membrane was flat and smooth surface. The conformation of silk fibroin was $\beta$-sheet structure. When the silk membrane was applied on the rat calvarial defect model, it showed significantly higher new bone formation than uncovered control in histomorphometric analysis. The silk membrane was covered by thin fibrotic tissue and there was not observed any inflammatory cells infiltration. In conclusion, silk fibroin membrane could be useful materials for guided bone regeneration.
