Abstract:

Objective To study the different incidence of dry socket affer the third mandibular molars extraction using two different methods: implantology surgical unit and conventional method. Methods 156 patients were selected randomly, 156 impacted lower third molars on one side were removed with implantology surgical unit method; 107 lower 3rd molars on the other side by conventional chisel method (self control). The number of dry sockets were recorded. Results The incidence of dry socket in implantology surgical unit group was significantly lower than the conventional group. There were significant differenes between incidence of dry socket of the two methods (P=0.013). Conclusion The implantology surgical unit method is safer, more time-saving and less traumatic than the conventional chisel bone method. The study indicated the former is effective in dry socket prevention.
