Abstract:
The aim of this study is to evaluate the technique of surgical guide in the extraction of impacted supernumerary mandibular premolars. This case series included 5 patients. Impacted supernumerary mandibular premolars were removed through a lateral window approach using the surgical guides. The mental nerve and adjacent teeth were properly protected by our custom made surgical guides. All cases successfully underwent the operation. An average of 5.01 ± 1.10 min was required to locate the supernumerary mandibular premolar. There were no complications involving injury to the mental nerve injury or adjacent teeth in any case. The application of custom-made surgical guides in the extraction of impacted supernumerary mandibular premolars showed an acceptable clinical outcome in this case series.
