Bimaxillary Molar Distalization Using Clear Aligners To Correct Severe Crowding Without Temporary Anchorage Devices

The use of clear aligners for molar distalization has been a hot topic in recent years. However, cases of bimaxillary molar distalization without temporary anchorage devices (TADs) are rarely reported. Dental crowding, one of the most common malocclusions in the Asian population, was often corrected by tooth extraction strategies in the past. Currently, in the application of molar distalization with clear aligners by orthodontic professionals, it becomes feasible to circumvent the necessity for tooth extraction or TADs in numerous cases that initially present as markedly crowded. A 29-year-old female sought treatment for dental crowding. Subsequent examination revealed that her upper dentition was moderately crowded, while the lower dentition exhibited severe crowding. The patient declined the extraction treatment option and requested clear aligners based on consideration of esthetics during orthodontic treatment. Drawing from the patient's chief complaint and specific requirements, an orthodontic procedure of bimaxillary molar distalization was implemented. Following the completion of clear aligner treatment, the patient achieved well-aligned teeth and a captivating smile, radiating enhanced esthetics. The satisfactory treatment outcomes confirmed the efficacy of clear aligners for molar distalization. With a well-considered anchorage plan, clear aligners can successfully achieve bimaxillary molar distalization without the necessity of TADs.
