摘要：

目的:探讨骨性安氏Ⅱ类错　患者采用外科—正畸联合治疗后颜面软组织侧貌在矢状和垂直方向上的变化。方法:选用华西医科大学口腔医院正畸科连续收治的骨性安氏Ⅱ类错　患者22 例,男7 例,女15 例,年龄20～30 岁。在术前及术后6～12 个月摄取X线头侧位片, 对16 个软硬组织标志点的变化进行矢状、垂直向的分析。结果:在矢状向上,上唇沟点、上唇缘点、上唇下点后退均大于2 mm( P < 0101) ;与上切牙点后移量之比为0159∶1～0164∶1 ;颏唇沟软、硬组织点前移量之比为0183∶1 ,软组织颏前点与硬组织颏前点前移量之比为0195∶1。在垂直向上,鼻尖点、鼻底点、上唇缘点平均向上移动量均小于1 mm( P > 0105) ;但软组织颏前点、颏唇沟、下唇缘点、下唇上点向上移动量均大于2 mm( P < 0105) ,与相应的硬组织移动量之比为1107∶1～1134∶1。结论:骨性安氏Ⅱ类错牙合患者经外科—正畸联合治疗后颜面软组织侧貌改善明显。在矢状方向,上下颌软组织改变量均小于硬组织;但在垂直方向,下颌软组织的改变却比硬组织更明显。

Abstract:

One of the prime concerns of both the orthodontist and the oral surgeon must be the final soft tissue profile and the esthetic appearance of the patient. The purpose of this study was to evaluate the amount , direction , and predictability of the soft tissue changes associated with simultaneous skeletal changes.Methods :The authors analyzed the recent 22 cases with skeletal class II malocclusion in Orthodontic Department , College of Stomatology , West China University of Medical Sciences with 7 male and 15 female from 20 to 30 years old. Each patient was taken standardized lateral cephalograms before the treatment and 6～12 months after the treatment. A total of 16 hard and soft tissue landmarks were evaluated in both horizontal and vertical directions.Results : In the horizontal directions , the soft tissue maxillary landmarks (superior labial sulcus , labrale superius , and upper lip stomion) moved posterior with a range of 2. 17 to 2. 33 mm. The strongest correlations were found between the posterior movement of the up2 per incisal edge and the three soft tissue parameters : superior labial sulcus r = 0. 78 , labrale superius r = 0. 81 , upper lip stomion r = 0. 75. The softPhard tissue ratios of the mandible anterior movement is 0. 83∶1 between inferior labial sulcus and B point , and 0. 95∶1 for Pog′to Pog. In the vertical directions , all the soft tissue mandible landmarks (Pog′, inferior labial sulcus , labrale in2 ferius , lower lip stomion) moved upward more than 2 mm. And the softPhard tissue ratio is from 1. 07∶1 to 1. 34∶1. Conclusion : The combined orthodontic and surgical treatment is an efficient way to cure skeletal class II malocclusion. All the patients regained satisfactory face appearance and profile. Although the soft tissue movement is less than the hard tissue in both jaws in the horizontal direction , the vertical movement of the mandibular soft tissue is greater than that of the underlying hard tissue.
