Assessment on extraction of mandibular near impacted with different techniques

Objective To Observe high-frequency electronic-knife combined with high speed turbine drill extracting mandible near impacted in comparison of clinical curative effect.Methods Choose 52 patients which had bilateral mandibular third molar near impacted and need to pull out.At two times respectively using High frequency high-frequency electronic-knife with high speed turbine drill extracting method on one side(treatment group) and another side with traditional method with teeth pulling cut hammer(control group).The two groups′ operating time,postoperative local swelling and mouth degrees were compared and analyzed.Results The operation time,operation effect and the postoperative complications of treatment group were much better than control group,two groups was statistically significant difference(P0.05).Conclusion High-frequency electrotome combined with high speed turbine drill extracting method can achieve tooth shorten the timing of the operation,reduce the complications of purpose.
