The requirements for bone grafting materials should be that they must be able to maintain space for bone regeneration to occur and must be resorbed by osteoclasts and replaced with new bone tissue occurring in passive chemolysis and bone remodeling. Carbonate apatite (CO3Ap) granules (Cytrans Granules, GC) are chemically synthetic bone graft material that are similar to autologous bone mineral and more biocompatible than allografts and xenografts. The aim of this report is to evaluate the efficacy of CO3Ap granules in implant treatments using CO3Ap granules in combination with autogenous bone or CO3Ap granules separately. This report will show the clinical findings as well as radiographic and histological assessments in three cases of immediate implant placement, lateral GBR and vertical GBR. These results demonstrated, although it was a short-term report, that in histological findings CO3Ap granules were efficiently resorbed and replaced bone in clinical use. Furthermore, the clinical findings showed that CO3Ap granules contributed to maintaining their morphology tissue around the implant. In this limited short-term case report, it was suggested that this bone substitute was effective. However, further clinical studies and long-term reports of this new biomaterial are needed.</p>","PeriodicalId":54948,"journal":{"name":"International Journal of Periodontics & Restorative Dentistry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10203276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
