Camouflage treatment for skeletal Class III patient with facial asymmetry using customized bracket based on CAD/CAM virtual orthodontic system: A case report

摘要

When considering camouflage orthodontic treatment for Class III malocclusion with skeletal facial asymmetry, it is crucial to preserve the favorable compensated posterior occlusion. Once the inclination of the compensated occlusion is changed during orthodontic treatment, unstable occlusion, such as crossbite or scissor bite may occur. A 23-year-old female patient had anterior spacing with Class III malocclusion and a mandibular asymmetry. A nonsurgical approach was adopted. The treatment objectives were to establish a Class I molar relationship with compensated inclination of the posterior dentition and to correct the midline deviation. To achieve these goals, the computer-aided design/computer-aided manufacturing (CAD/CAM) orthodontic system plus customized brackets was applied, and miniscrews were used to distalize the left mandibular dentition for midline correction. The results suggested that the CAD/CAM-based customized brackets can be efficiently used in camouflage treatment to achieve a correct final occlusion.
