Abstract
Class II malocclusion is one of the most frequent treatment problems facing orthodontists, representing nearly one third of all malocclusions. If the problem is caused by a dental factor several treatment options have been attempted including distalization of the maxillary first molar. In 2004 a new appliance was introduced by luis carrière carrying his name, called the carrière motion appliance 10. However, so far no RCT in the orthodontic literature evaluated the use of this appliance. The aim of this study was to evaluate anchorage control using miniscrews vs Essix appliance in treatment of post-pubertal patients with Class II malocclusion using carrière motion appliance. A randomized clinical trial was conducted consisting of 24 participants with age range between 14-30 years old. The participants were divided equally into two groups, the first group consisted of 12 patients who were treated using the carrière motion appliance and 2 miniscrews inserted between the first mandibular molar and second premolar bilaterally. The second group consisted also of 12 patients who were treated using the carrière motion appliance and an essix appliance in the lower arch. The treatment effects were evaluated radiographically using pre and post-distalization CBCT images after either class I molar relation has been reached or an observation period of 9 months has elapsed
