Fig. 1From: Influence of maxillary molar distalization with clear aligners on three-dimensional direction: molar distal movement, intrusion, distal tip and crown buccal torqueThe superimposition of the pretreatment model and the model after distalization. A Pretreatment. B Selecting the palatal rugae area (pretreatment). C Second scan after maxillary molar distalization. D Selecting the palatal rugae area (after distalization). E Local best fit after selecting the palatal rugae area of the two modelsBack to article page
