Abstract：Objective To compare the five-year success rate of implant and the alveolar bone absorption around the implants implanted with conventional drilling technique or osteotome technique in the posterior maxilla which is Ⅲ sclerotin. Methods A total of 111 implants from 82 cases treated in the Oral Implantology Center of Affiliated Dental Hospital of China Medical University in the posterior maxilla (Ⅲ sclerotin) between January 2010 and December 2011 were enrolled in this study. According to whether with osteotome technique or not, these cases were divided into conventional drilling technique group and osteotome technique group. Postoperative follow-up lasted for 5 years;calculate the fiveyear success rate of the two groups and the alveolar bone absorption around the implants at the first half year, 1 year, 2 years and 3 years after implantation;compare the five-year success rate and the alveolar bone absorption around the implants implanted with conventional drilling technique or osteotome technique in the posterior maxilla which is Ⅲ sclerotin. Results The five-year success rate of conventional drilling technique group and osteotome technique group in the posterior maxilla (Ⅲ sclerotin) was 96.23％ and 98.28％ respectively, the differences being insignificant (P＞ 0.05). The differences in the alveolar bone absorption around the implants was insignificant (P＞ 0.05) at the lst, 2 nd and 3 rd year of implantation, but was significant in the first half year after implantation (P ＜ 0.05). Conclusion In the implanting in posterior maxilla (Ⅲsclerotin), no significant statistical differences in the five-year success rate or the alveolar bone absorption around the implants is found long-term effects between the two methods. Therefore, in implantion of Ⅲ sclerotin in posterior maxilla, performer of the implantation can decide whether osteotome technique is performed according to the early stability of the implant.
