Abstract：Objective To research the healing of impacted mandibular third molar through atraumatic extraction so as to further verify the advantages of atraumatic extraction. Methods Totally 100 cases of male patients with median-leaning forward impacted mandibular third molar from September 2010 to October 2012 in Chancheng District Xiangyang Hospi-tal of Foshan were selected as experiment group and control group at random. Each group had 50 cases. For the experi-ment group,we adopted atraumatic extraction. For the control group,we used traditional extraction. Then we compared the differences in postoperative edema,pain and limited mouth opening of two groups,and observed two groups density curve of the alveolar bone in the healing process. Results For the experiment group,postoperative edema and pain rates were lower than the control group(P<0.05),the value of density change of alveolar bone was significantly higher than the control group after 4,8,12 weeks(P<0.01). The differences between two groups had statistical significance. The limited mouth opening rates in two groups had no statistical significance(P>0.05). Conclusion Atraumatic ex-traction is good for the healing of tooth socket,which is worthy of clinical popularization and application.
