Influence of maxillary molar distalization with clear aligners on three-dimensional direction: molar distal movement, intrusion, distal tip and crown buccal torque

Progress in Orthodontics, 2023
Background The aim of this study was to evaluate the distal movement, vertical movement, distal tipping and crown buccal torque of maxillary molars after the completion of distalization by comparing the predicted movement with the achieved movement using

Molar distalization and stability following maxillary anterior teeth alignment with class II elastics and a 10-day aligner protocol [PDF]

Scientific Reports
This study compares the anticipated maxillary anterior teeth alignment and molar distal movement with the actual results. The molar stability after anterior teeth alignment has also been investigated. The sample consisted of 30 individuals. Three digital

Evaluation of maxillary miniscrew-anchored molar distalization appliance versus clear aligners in adult with Class II malocclusion: study protocol for a randomized controlled trial [PDF]

Trials
Background Angle Class II malocclusion typically presents with overbite, distal molar relationship, and crowding of the upper anterior teeth. The distal movement of the maxillary molars is considered an optimal treatment strategy, as it can circumvent ...

Nonextraction Treatment of a Class III Malocclusion Case Using Mini-Screw-Assisted Lower Molar Distalization [PDF]

Turkish Journal of Orthodontics, 2019
Mini-screw assisted lower molar distalization was planned for a present mild Class III malocclusion case. Two mini-screws were inserted into the available inter-root area: one on the left, and the other on the right side in the posterior region in the ...
