comparative study between two types of bone graft in dental implant

Introduction osseointegration around dental implant is the key word of implant stability and bone grafts have a big share for enhancing osseointegration . Aim of the study: To evaluate the efficacy of two different types of bone graft, the (OsteonII) and (Biogen). Patients and methods: This study was carried out on fifteen healthy male patientswith averageage from 20 to 40 years old.. 15 immediate dental implants were dividedinto (group1)immediate placement of 6 dental implant into fresh extracted bony socket with bone graft OsteonII,(group 2) immediate placement of 6 dental implant with bone graft BioGen and in, (group 3)immediate placement of 3dental implant into fresh extracted bony socket without bone graft.Clinical examination was donefor all patients befor surgery. Radiographic evaluation using CBCT was done after 2weeks and 3, 6 months postoperatively to measure bone density around inserted implants and vertical bone loss. Results: Radiographic evaluation showed significant higher bone density and lesser vertical bone loss around the inserted implants in groupII than groupI after two weeks, 6 and 9 months. Also, implant stability measurements at six and nine months showed higher values in group II than in group I. 4 / 21 Conclusion: immediate implant placement can be done successfully using either OsteonII or BioGen bone grafts but, BioGenare superior with using immediate dental implant than OsteonII regarding bone density and implant stability around implant. Key words:Alloplastic bone grafts-Immidiate placement-CBCT–Implant stability.
