Clinical study of extracting mandible impacted third molar with bone chisel and turbine dental drill and bone chisel method

Objective To explore the apply of the use of turbine dental drill and bone chisel method in extracting each kind of mandible impacted tooth, analytical with bone chisel. Methods 1789 tooth extractions were analyzed, which included 226 operation complications and 287 after operation complications. Results In 1789 examples, adopt the bone chisel method to pull out 789, operation complications were 140 example, share 17.74%.After operation complications were 165, share 20.91%.Adopt another method to pull out 1200, operation complications were 86, share 7.1%.After operation complications were 124, share 10.33%. Two sets of method were significantly different(P0.01).The operating time of the bone chisel and turbine dental drill plus bone chisel method were significantly different(P0.01). Conclusions To pull out every variety mandible impacted third molar use the turbine dental drill plus bone chisel method,the wound is small,time is short and apply accurate,easy to protect,can lower complications after operation.
