目的 :结合临床实际 ,建立一个正畸治疗中软组织侧貌改变的矫治预测系统 ,并对系统进行实用性的可行性论证。方法 :自主开发侧貌预测软件HOPS 40 0 ,以所建系统对 2 4例安氏Ⅱ类 1分类错功能矫治的软组织头影测量预测结果和治疗结果进行对比分析 ,比较二者的一致程度。结果 :在 95 %可信限内 ,3种软组织头影测量分析方法 (Burstone ,Holdway,Bishara)中的 30项指标有 19项一致 ;尤其是 9项角度测量指标有 7项一致 ;18项线距测量结果有 10项一致 ;3项线距比指标也有 2项一致。结论 :预测结果对临床有一定的指导作用
OBJECTIVE: To establish an orthodontic and orthodontic treatment system for orthodontic treatment based on clinical practice, and to demonstrate the practicability of the system. Methods: The software HOPS 40 0 was independently developed to compare the predictive value and treatment outcome of soft tissue cephalometric analysis of 24 patients with Class Ⅱ division 1 malocclusion by the proposed system, and to compare the consistency between the two . RESULTS: Within the 95% confidence limit, 19 of the 30 indices in the three soft tissue cephalometric analysis methods (Burstone, Holdway, Bishara) were consistent; in particular, seven of the nine angle measurements were consistent; 18 lines 10 measurements from the same; 3 line spacing than the index there are two consistent. Conclusion: The results of the prediction of clinical guidance
