Application Research of Tooth Arrangement Based on Rotation Matrix Calculation and Resistance Detection in Oral

Figure 6

Graph depicting the three-dimensional displacement of the maxillary right centralized incisor, canine as well as lateral incisor during two months of therapy. The angle of rotation and amount of translation with a helical axis is++ used to indicate tooth movement. T0: shortly before device application; T1: instantly after device implementation; T2: Ten days of treatment; T3: one month of treatment; T4: Two months after therapy. The white bar represents the rotation axis; the curved arrow represents the rotation angle; and the little straight arrow represents the translation amount.
