Extraction of Mandibular Mesioangular Impacted Wisdom Teeth

Abstract

The crown of the mandibular wisdom teeth is in an anterior tilting state in the mandible before eruption. If tracking the growth trace, the crown of the wisdom tooth displays “mesially tilting” → “drifting”—“uprighting” → alveolar ridge → “eruption.” Due to the degeneration of the human jaw and the narrow space behind the molars, the growth path will be stagnant once the crowns of the wisdom tooth meet resistance. Therefore, the mesioangular impacted wisdom tooth occupies the majority of the impacted wisdom teeth. Mesioangular impacted wisdom tooth is often accompanied by second molar impaction. Thus, the key step of removal of mandibular mesioangular impacted wisdom tooth is to “remove the tooth resistance.”
