Abstract
Class II malocclusion constitutes the major part of dentofacial
abnormalities. Its frequency being reported as approximately one-third of the patients seeking orthodontic therapy. Class II malocclusions are treated by
several different techniques. The choice of treatment method is dependent on
many factors, some of which include: the patient’s age, the amount of jaw
discrepancy, the severity of the Class II molar relationship, the amount of
space available in the arch, and the compliance of the patient. In treating Class
II malocclusions, molar distalization has been among the preferred methods
of non-extraction treatment. Many devices have been developed and used to distalize the maxillary molars and show positive clinical results.
In 2004, a new appliance was introduced by Luis Carrière carrying his
name, called Carrière Motion appliance. However, so far no RCT in the orthodontic literature evaluated the use of this appliance(5). This study aiming to evaluate the skeletal, dental and soft tissue changes using Carrière Motion appliance with three different anchorage methods in treatment of post-pubertal
patients with class II malocclusions.
A randomized clinical trial was conducted consisting of 30 participants with age range between 15-18 years old. The participants were randomly allocated into 3 groups. Ten patients in group I were treated using Carrière Motion appliance with Essix appliance in the lower arch. In group II, 10 patients received treatment with Carrière Motion appliance using direct anchorage by 2 miniscrews inserted between the first and second mandibular molars bilaterally and 10 patients in group III were treated using Carrière Motion appliance with indirect anchorage by lingual arch and 2 miniscrews bilaterally.
