Abstract:
Objective:To analyze the efficiency and safety of navigation guided extraction of impacted supernumerary tooth.
Methods:Twenty-five cases of navigation guided supernumerary tooth extraction and 25 cases of non-navigation guided supernumerary tooth extraction (control group) were included in the study. Each group had 3 cases with one impacted supernumerary tooth and 22 cases with two impacted teeth.
Results:Preoperative navigation system designing time was (45.0±8.0) min in average. Navigation system installation time was (15.0±2.8) min. The average operation time was (0.64±0.08) hour in navigation group and (0.91±0.09) hour in control group.
Conclusions:Navigation guided extraction of impacted supernumerary tooth takes less time for operation but more time for the preoperative navigation system design.
