摘要: 目的: 探讨采用肌功能增强器与直丝弓矫正技术联合矫正上颌前突的临床效果。方法: 选择40例上颌前突患者,分为A、B 2组。A组采用肌功能增强器与直丝弓矫正技术联合矫正,B组单独采用直丝弓矫正。拔牙矫正6个月后拍摄X线片,评估矫正效果,测量上颌骨各项指标:上、下切牙的唇倾度、SNA、SNB、FMA、上颌平面角、颌凸角、U1-FH、U1-PP、U6的前移量。2组的测量值采用SPSS20.0软件包进行t检验。结果: A组上、下切牙的唇倾度、SNA、SNB、FMA、上颌平面角、颌凸角、U1-FH、U1-PP矫治前后比较有显著差异(P<0.05),B组上、下切牙的唇倾度、SNA、SNB、FMA、上颌平面角、颌凸角、U1-FH、U1-PP矫治前、后比较也有显著差异(P<0.05);A组矫治后的SNA、U1-SN、A-Nv、U1NP上、下切牙的唇倾度、SNA、SNB、FMA、上颌平面角、颌凸角、U1-FH、U1-PP显著优于B组(P<0.05),即A组比B组切牙内收更多,且U6的近中移动更少。结论: 上颌前突病例多数有口呼吸的不良习惯,肌功能增强器为夜间使用,可解除患者口呼吸,加快牙移动,减少支抗丧失,提高矫正效率和效果。

Abstract: PURPOSE: To investigate the clinical effects of combined muscle functions intensifier and straight wire appliance in the treatment of maxillary protrusion. METHODS: Forty patients with maxillary protrusion were randomly divided into 2 groups (group A and group B). Straight wire appliance and muscle function intensifier were used in group A, while patients in group B received straight wire appliance only. X-ray projection was conducted to measure relative maxillary index (labial inclination of upper or lower incisor, SNB angle, ANB angle, FMA, maxillary plane angle, NA-PA, U1-FH, U1-PP, forward moving distance of U6) before and 6 months after treatment. The efficacy was analyzed and evaluated using SPSS 20.0 software package. RESULTS: After correction, labial inclination of upper or lower incisor, SNB angle, ANB angle, FMA, maxillary plane angle, NA-PA, U1-FH, U1-PP changed significantly in both groups (P<0.05), but patients in group A achieved more incisor adduction and less forward moving distance of U6, with significant difference between the two groups (P<0.05). CONCLUSIONS: Most patients with maxillary protrusion have a bad habit of mouth breathing. Muscle function intensifier is used only at night and can relieve the patient's mouth breathing, speed up the movement of teeth, and reduce the loss of anchorage and ultimately, improve the correction efficiency and clinical effect of patients with maxillary protrusion.
