Abstract: PURPOSE: To compare the clinical effect of using piezosurgery device and traditional method in extraction of horizontally impacted mandibular third molar. METHODS: Two hundred and forty patients with horizontally impacted mandibular third molar were equally divided into 2 groups: using piezosurgery device and traditional method for extraction. The operation time, intraoperative and postoperative complications including deformation of extraction sockets, dry socket, limitation of mouth opening, pain and swelling, and fear were observed and compared between the two groups. The data were analyzed with SPSS 13.0 software package. RESULTS: The operation time was (18.0±6.3) min in the minimally invasive extraction group, significantly shorter than the traditional method group which was (37.0±8.2)min (P<0.05); significant difference was found in the incidence of medium or severe tooth sockets deformation and incidence of psychological fear during operation between the two groups(P<0.05); the degree of mouth opening after surgery, the incidence of moderate or severe pain after surgery was significantly lower in the group with piezosurgery device than in the group with traditional method (P<0.05). CONCLUSIONS: Minimally invasive extraction with piezosurgery device is better than traditional method in extraction of horizontally impacted mandibular third molar, with shorter operation time and fewer intraoperative and postoperative complications, which should be widely applied in clinic.
