| Abstract: The method of tooth extraction may affect amount of bone and thus may affect orthodontic tooth movement. Materials and Methods:This study is a split mouth clinical trial. A total of 14 female patients were enrolled in the study. Following the leveling and alignment stage, the patient was sent for extraction either with conventional forceps way for one side and the other side with the aid of the Piezotome. Results:The average rate of canine retraction for the four months of the study and the total amount of canine retraction weren’t significant. Regarding marginal bone loss,in control side (forceps extraction side) mean marginal bone loss was found to be 0.07 mm (+_ 0.1). In the piezotome side mean marginal bone loss was found to be 5.8 mm (0.23).The difference between two sides was statistically significant (p<0.05). Conclusions:The method of teeth extraction didn’t affect the rate of canine retraction into the extraction socket. Piezotome was believed to produce more atraumatic extraction, however the amount of marginal bone loss was significantly greater compared to the conventional forceps extraction method. | ||
