Abstract: As the most common surgical operation in oral surgery clinics, the core of mandibular third molar extraction is to effectively relieve the resistance of adjacent teeth, bone and soft tissues. Mesial and horizontal impaction, the most prevalent form of impaction, frequently results in the coexistence of adjacent teeth and bone resistance due to their anatomical position. The evolution of surgical instruments, from the splitting chisel method to high-speed turbine handpiece technology, and the subsequent development of novel instruments such as ultrasonic bone knives, has underscored the pivotal role of the sectioning method in overcoming resistance. This article reviews the sectioning methods and techniques in minimally invasive extraction of mandibular third molars, with a view to improving extraction efficiency and serving as a reference for clinicians.
