A new method of treating orthodontic malocclusion has evolved over 27 years of clinical effort to formulate anchorage requirements, treatment timing sequences, and treatment control. I have used a punch-card system to evaluate approximately 80 percent of my posttreatment results. Data from 20 patients were selected for presentation. The subjects all responded well with excellent posttreatment occlusion. Preorthodontic treatment goals such as cephalometric values, arch form, and function were achieved to my satisfaction. Average treatment time was longer than that estimated by only 6.5 percent. The subjects represent a wide variety of orthodontic problems with extraction and nonextraction choices and provide corroboration for the proposed efficiency of this method.
经过27年的临床实践，一种治疗正畸错颌畸形的新方法逐渐形成，该方法确定了支抗要求、治疗时间顺序和治疗控制。我使用穿孔卡片系统评估了约80%的治疗后结果。选取了20名患者的数据进行展示。所有受试者反应良好，治疗后咬合情况极佳。正畸治疗前设定的目标，如头影测量值、牙弓形态和功能，都达到了令我满意的效果。平均治疗时间比预期仅长6.5%。这些受试者代表了各种正畸问题，包括拔牙和不拔牙的选择，为该方法的预期效率提供了佐证。
