ACCURACY OF CLEAR ALIGNERS FOR INCISOR TORQUE IN ORTHODONTIC TREATMENT

This systematic review aimed to evaluate the accuracy of clear aligners in achieving incisor torque during orthodontic treatment. A 10-year data search was conducted based on specific inclusion criteria such as randomized control trials cross-sectional studies and FEM studies involving patients undergoing aligner treatment. Out of 291 studies 8 met the inclusion criteria and were included in the review.The review found that clear aligner accuracy in achieving programmed incisor torque varied with average success rates as low as 41%. Power ridges and attachments emerged as essential tools improving torque control but requiring over-correction to counteract torque loss. The findings highlight the need for further research and optimization to enhance clear aligner performance in orthodontic treatments.
