INTRODUCTION: Immediate implant placement is now accepted in clinical dentistry for reconstruction of partially or completely edentulous mandible or maxilla.
OBJECTIVES: The aim of the study was to evaluate the role of Maxgraft bone rings on the marginal bone level around dental implants placed in fresh extraction sockets.
MATERIALS AND METHODS: A randomized clinical trial was carried out on fourteen cases with freshly extracted sockets with age range 20 to 50 years. There were 2 groups, study group and control group, the sockets of the study group were filled with the new “Maxgraft bone ring" and an immediate placement of implants were carried out in the graft site, while the control group sockets had immediate implant placement alone. A clinical and radiological evaluation were carried out immediately postoperatively, after 3 & 6 months to assess the osteointegration of the implant placed and to measure the level of the marginal bone around the implant. After 6 months final prosthesis was delivered.
RESULTS: Radiographic evaluation revealed increase in marginal bone level around implants placed in the Maxgraft bone rings than those placed alone with statistical significance (p1 =0.008)
CONCLUSIONS: Increase in marginal bone level using the Maxgraft bone rings due to its osteoconductive properties supporting natural and controlled tissue remodeling together with the trabecular structure of the cancellous bone within the graft allow optimal graft revascularization, rapid formation of new bone tissue and bone remodeling.
