Mandibular horizontally impacted horizontally impacted teeth (MHIT) often require extraction due to complications such as pericoronitis, caries, and periodontal disease. This study explores the efficacy of the "" shaped crown sectioning method for these extractions. From May 2021 to May 2023, 240 patients undergoing extraction of MHIT were randomly and double-blindly assigned to the study group. (n = 120) using a micro-power system or the control group (n = 120) using an ultrasonic instrument. Key outcomes measured included operation time, alveolar damage, postoperative pain (VAS), mouth opening degree, and wound healing. The study group showed shorter operation times, lower alveolar damage scores, lower VAS scores, greater mouth opening degrees, and better wound healing than the control group (P <
.05). The "" shaped crown sectioning method significantly reduces buccal alveolar bone removal, operation time, alveolar damage, and postoperative pain while improving mouth opening and wound healing, demonstrating substantial clinical value.
