Objective: To summarize the clinical advantages of ultrasound boneknife in odontectomy of mandibular impacted wisdom teeth. Methods: One hundred and five patients with impacted wisdom teeth of the mandible were randomly divided into three groups and provided informed consents. Group A(n=35), ultrasound bone knife was used for odontectomy; Group B (n=35), high speed turbine drill acted as the instrument; Group C(n=35), conventional ossisectors, elevators, and exolevers were used. The operative time length, intraoperative blood loss, patients' subjective feeling, and pain degree were recorded and evaluated. Statistical analyses were performed with SPSS 19.0 software. Results: The operation time length between three groups were different, Group A> Group C>Group B. Intraoperative blood loss: Group C>Group B>Group A. Group A patients had the least effect on the mouth opening, the degree of pain and the increment of the buccal circumference. Dry socket syndrome and proportion of complications in Group C patients were significantly higher than the other two groups. Group C patients had the worst subjective feelings. Conclusion: The use of ultrasonic bone knife in odontectomy demonstrates more advantages.
