An integrated approach to posterior anchorage preparation and incisor torque compensation in premolar extraction cases using clear aligners

Abstract Background In clear aligner treatment (CAT), closure of the premolar space is achieved by reducing aligner length. Posterior anchorage preparation is effective in preserving molar angulation; however, the resulting distal tipping can contribute to anterior anchorage loss. This study aims to...
