Comparison Of The Effect Of Chisel Osteotomy And Piezosurgery In The Extraction Of Mandibular Impacted Third Molar

Objective: To compare the effect of chisel osteotomy and piezosurgery in the extraction of mandibular impacted third molar, compare in the surgery time, intraoperative and postoperative complications, and select the appropriate extraction method for clinical reference. Methods: Impacted teeth on both sides of a similar type of 60 patients(120 mandibular impacted third molar) were randomly divided into A, B groups, using traditional chisel chop bone knife crown and ultrasonic bone impacted wisdom teeth on the lower jaw be pulled surgery, surgery time interval in two month, limited mouth opening degree of postoperative pain, swelling and blood loss record, and the results were analyzed statistically. Results: The use of ultrasound treatment of jaw bone knife low time impacted wisdom tooth surgery patients, bleeding and postoperative pain were less than the control group, the number of postoperative swelling and trismus significantly less than the control group, the difference was significant, with statistical significance(P<0.05). Conclusion: Ultrasound bone knife turbine combined to form a complementary advantages, to better reflect the characteristics of minimally invasive surgical alveolar, but also can be used as a method to improve the operation of the turbine, is worthy of further promotion.
