目的:研究超声骨刀开窗术联合正畸牵引治疗上颌唇侧埋伏阻生尖牙的临床疗效。方法:选取2013年7月到2015年4月我院收治的上颌唇侧埋伏阻生尖牙患者110例,按照随机数字表法将患者分为研究组和对照组,每组55例,研究组给予超声骨刀开窗术联合正畸牵引治疗,对照组给予传统开窗联合正畸牵引治疗,比较两组临床疗效。结果:研究组总有效率92.7%,对照组总有效率90.9%,两组比较差异无统计学意义(P>0.05);研究组一次粘结成功率85.5%显著高于对照组的52.7%,两组比较差异具有统计学意义(P<0.05);研究组术后疼痛和肿胀程度均显著低于对照组,两组比较差异具有统计学意义(P<0.05)。结论:超声骨刀开窗术联合正畸牵引治疗上颌唇侧埋伏阻生尖牙疗效良好,且能显著降低术后反应。
Objective: To study the clinical effect of ultrasonic osteofectomy combined with orthodontic traction on maxillary labial obstruction impacted canines. Methods: From July 2013 to April 2015, 110 patients with maxillary labial obstruction impacted canines admitted from our hospital were divided into study group and control group according to the random number table method, with 55 cases in each group. The study group Ultrasound osteotomy combined with orthodontic traction treatment, the control group were given traditional fenestration orthodontic traction treatment, the clinical efficacy of the two groups were compared. Results: The total effective rate was 92.7% in the study group and 90.9% in the control group, with no significant difference between the two groups (P> 0.05). The successful rate of primary bonding in the study group was significantly higher than that of the control group (85.5% vs 52.7% The difference between the two groups was statistically significant (P <0.05). The postoperative pain and swelling in the study group were significantly lower than those in the control group. There was significant difference between the two groups (P <0.05). Conclusion: Ultrasound osteotomy combined with orthodontic traction in the treatment of maxillary labial obstruction impacted canines is effective and can significantly reduce the postoperative response.
