Abstract: Objective:To compare the outcomes of guide bone regeneration by calcined bovine bone and Bio-Oss graft material in alveolar ridge preservation after tooth extraction.Methods:280 patients were divided into two groups randomly.Each patient had single tooth extracted.The sockets were filled with calcined bovine bone in 140 patients and Bio-Oss graft in another 140 patients. After shaping,all the sockets were covered with Bio-Gide membrane.Buccal mucoperiosteal flap was released and sutured to close the alveolar sockets.The patients were regularly examined at the 1st,12th and 24th week after surgery.Physical examination and X-ray evaluation were applied to compare the outcomes of the two materials in alveolar ridge preservation.Results:No infection and re-jection occurred.The radiographic results showed the width and height of the alveolar bone were preserved well at the 12th and 24th weeks.No statistically difference was found in the two groups at the 1st and 24th weeks(P>0.05).Conclusion:The two graft ma-terials can effectively preserve alveolar bone after tooth extraction.
