Sophisticated treatment planning for those individuals with severe dental and facial disproportions requires accurate prediction of posttreatment results. Preand posttreatment cephalometric X-rays for a group of twelve patients treated by a combined orthodontic-oral surgical approach were evaluated. The surgery was of either the standard mandibular subapical osteotomy or Kole type of procedure. Surgical repositioning of the anterior mandibular alveolus resulted in various changes in hard tissue and soft tissue profile. In summary, these changes were: 1. Decreased lower facial height. 2. More relaxed lip posture as revealed by an increased superior vermilion lip length and decreased inferior vermilion lip length. 3. Stomion moved inferior and posterior relative to the lower facial plane. 4. Superior labial sulcus became less concave. 5. Inferior labial sulcus became more concave. 6. Superior vermilion and inferior vermilion moved posterior relative to the lower facial plane. 7. Chin radius and lip-chin-throat angle decreased. 8. Overbite and overjet increased while Wits analysis decreased. 9. Facial contour angle was unchanged. Changes were similar for both standard subapical and Kole groups with the main difference being a greater reduction in facial height with the Kole group.
对于那些患有严重牙齿和面部比例失调的患者，复杂的治疗计划需要准确预测治疗后的结果。对一组采用正畸-口腔外科联合治疗方法的12名患者的治疗前和治疗后的头颅侧位X线片进行了评估。手术采用标准下颌根尖下截骨术或科尔氏手术。下颌前牙槽骨的手术重新定位导致硬组织和软组织轮廓发生各种变化。总之，这些变化包括：1. 面下高度降低。2. 上唇红长度增加和下唇红长度减少表明唇部姿势更加松弛。3. 口角相对于面下平面向下和向后移动。4. 上唇沟凹陷程度减轻。5. 下唇沟凹陷程度加重。6. 上唇红和下唇红相对于面下平面向后移动。7. 颏半径和唇-颏-喉角减小。8. 覆合和覆盖增加，而Wits分析减小。9. 面部轮廓角不变。标准根尖下组和科尔氏组的变化相似，主要区别在于科尔氏组面高度降低幅度更大。
