摘要: 目的:比较隐形矫治与SGTB双期治疗下颌骨后退的临床效果。方法:选择未过生长发育高峰期的85例骨性下颌骨后退患者,隐形矫治前导40例,SGTB功能矫治导下颌45例。测量患者治疗前(T0)和矫治结束后(T1)的头颅侧位X线片,采用SPSS 16.0软件包比较患者治疗前后的效果。结果:治疗后2组的SNB角、NP-FH(面角)增大,ANB角减少,均有显著变化(P<0.001)。T1时,隐形组SNB角、ANB角、NP-FH角的变化量较SGTB组小(P<0.05);SGTB组的MP-FH角和MP-SN角在治疗前后的差异比隐形组大(P<0.001)。结论:对生长发育高峰期前的下颌骨后退患者进行矫治后,下颌骨明显前移,隐形矫治和SGTB都能促进下颌骨位置改变,改善上下颌骨的协调关系,但后牙垂直向控制,隐形组强于SGTB组。

Abstract: PURPOSE: To compare the clinical effects of invisible correction and SGTB in two-stage treatment of mandibular retrusion. METHODS: Eighty-five patients with bony mandibular regression who did not pass the peak of growth and development were selected. Among them, 40 cases were guided by invisible correction and 45 cases were guided by SGTB functional correction. Lateral head X-rays before and after treatment were measured, and the effect before and after treatment was compared by SPSS 16.0 software package. RESULTS: After treatment, the SNB angle and NP-FH (face angle) increased and the ANB angle decreased in both groups, all of which had significant changes(P<0.001). At T1, the changes of SNB angle, ANB angle and NP-FH angle in the invisible group were smaller than those in the SGTB group(P<0.05). The difference between MP-FH angle and MP-SN angle before and after treatment was greater in the SGTB group than in the invisible group(P<0.001). CONCLUSIONS: In patients with receding mandible before the peak of growth and development, the mandible was significantly moved forward after orthodontics. Both invisible orthodontics and SGTB promote changes in the position of the mandible, improves coordination between the upper and lower jaws. In the control of the posterior teeth in the vertical direction, the invisible group is stronger than the SGTB group.
