However, no improvement has been made so far with respect to the drawbacks of granules; i.e., intraoperative scatter and postoperative migration. The aim of this study was to evaluate the feasibility of fabricating a CO₃Ap-granules sponge to overcome these drawbacks. The CO₃Ap granules sponge was successfully fabricated by mixing 300–600 µm CO₃Ap granules with 3 % atelocollagen, followed by lyophilization at − 70 °C for 24 h and a dehydrothermal treatment at 150 °C for 24 h. The CO₃Ap-granules sponge and CO₃Ap-granules were implanted into rat calvarial bone defects for 2 and 4 weeks. No significant intraoperative scatter and postoperative migration were evident when the bone defects were reconstructed with the CO₃Ap-granules sponge, whereas significant both intraoperative scatter and postoperative migration were observed when the bone defect was reconstructed with CO₃Ap granules. Although less osteogenesis was anticipated for the CO₃Ap-granules sponge due to the coverage of CO₃Ap-granules surface with atelocollagen, no significant differences were observed in bone formation between the CO₃Ap-granules sponge and CO₃Ap-granules cases because the 3 % atelocollagen and lyophilization kept the CO₃Ap granules surface only partially covered. Consequently, the CO₃Ap-granules sponge and CO₃Ap-granules exhibited similar bone formation at both 2 and 4 weeks after surgery. Thus, the CO₃Ap-granules sponge improved the handling performance and retention ability at the bone defects without scarifying the osteogenesis of CO₃Ap-granules.</div></div>","PeriodicalId":45034,"journal":{"name":"Journal of Oral and Maxillofacial Surgery Medicine and Pathology","volume":"37 1","pages":"Pages 42-49"},"PeriodicalIF":0.4,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141138218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
