The Management of Class III and Class III Tendency Occlusions Using Headgear to the Mandibular Dentition

The use of extra-oral traction to the lower arch in the treatment of Class III malocclusion is described. The results of the treatment of 43 consecutive cases employing both removable and fixed appliances are analysed and compared with an untreated control group of 15 further cases. It was found that the Class III malocclusion in the study fell into three groups, the characteristic of each group giving an indication of the recommended treatment approach.
