Strategy to Remove Teeth Adjacent to Mesially Impacted Wisdom Teeth Based on a Geometric Analysis

: The present study aimed to establish a strategy to accurately remove teeth adjacent to mesially impacted wisdom teeth. Geometric principles were applied to analyze the resistance of teeth adjacent to mesially impacted wisdom teeth before extraction, and the resistance of adjacent teeth was relieved. The traditional method used to extract mesially impacted wisdom teeth is the chisel technique, which has been gradually replaced by minimally invasive extraction because of its great degree of trauma. This study determined the cutting method, cutting line position, and cutting direction of mesially impacted wisdom teeth based on imaging data from panoramic radiographs under geometric guidance. In the case of a short cutting line, cutting and separation were completed within one attempt, the resistance of adjacent teeth was alleviated, and the surgical duration was shortened.
