摘要
目的观察Forsus矫治器对生长发育高峰期下颌后缩患者牙、、颌面结构的影响。方法应用Forsus矫治器对15例生长发育高峰期的下颌后缩患者进行治疗,采取Pancherz二类错矫正分析方法结合传统测量项目分析治疗前后头颅侧位片。结果下颌体长度增加3.84mm,ANB角减小3.68°,SNB角增加3.20°,覆盖减少5.02mm,磨牙矢状方向改善4.62mm,有显著性差异,且表现为主要的骨性改变和部分的牙性改变。结论 Pancherz分析法可以明确反映下颌后缩患者治疗后颌面部组织在矢状方向上的变化;Forsus矫治器对青春生长发育高峰期患者有明显的下颌骨矫形效果,能促进下颌生长发育,有效地改善覆盖和磨牙关系。
Objective To observe the clinical effects of Forsus appliance in the treatment of Class Ⅱ malocclusion with mandibular retrusion during the peak stage of development.Methods Fifteen patients with Class Ⅱ malocclusion with mandibular retrusion were treated with Forsus appliance.At the beginning and the end of the treatment lateral cephalometric were taken and cephalometric analysis according to Pancherz＇s analysis were performed by Winceph 7.0 Cephalograms Analysis Software.Results The mandibular body length were increased by 3.84mm with ANB decreased 3.68°,SNB increased 3.20°.Overjet were decreased and molar relationship improved significantly,which was achieved mainly by the skeletal changes.Conclusion Pancherz＇s analysis can reflect the skeletal and dental effects quantitatively caused by functional appliances and is a direct and feasible evaluation method.Forsus appliance is effective to correct Class Ⅱ malocclusion at the peak stage of development.It can stimulate the mandibular growth and improve sagittal discrepancy and soft tissue profile convexity significantly.
