title: The level anchorage system for correction of orthodontic malocclusions.
abstract: 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.
