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.
下颌水平阻生牙(MHIT)常因冠周炎、龋齿和牙周病等并发症而需要拔除。本研究探讨“”形冠部截开法用于此类拔牙的疗效。2021年5月至2023年5月,240例行MHIT拔除术的患者被随机双盲分配至研究组(n = 120),使用微型动力系统,或对照组(n = 120),使用超声器械。测量的关键结局包括手术时间、牙槽骨损伤、术后疼痛(视觉模拟评分法[VAS])、开口度和伤口愈合情况。研究组的手术时间更短、牙槽骨损伤评分更低、VAS评分更低、开口度更大且伤口愈合情况优于对照组(P <.05)。“”形冠部截开法显著减少颊侧牙槽骨去除量、手术时间、牙槽骨损伤和术后疼痛,同时改善开口度和伤口愈合,具有显著的临床价值。
