Efficiency of ClearCorrect Clear Aligners in Achieving Anterior Tooth Movements

Background The aim of this study was to evaluate the efficiency and predictability of anterior tooth movements achieved using ClearCorrect clear aligners. Methods Pre- and post-treatment digital orthodontic models of 20 patients treated with ClearCorrect clear aligners were retrospectively analyzed. Three angular (angulation, inclination, and rotation) and four linear (intrusion, extrusion, mesiodistal, and buccolingual translation) tooth movements were assessed for the maxillary and mandibular central and lateral incisors, as well as the canines. Achieved tooth movements were quantified for each tooth following superimposition of the pre- and post-treatment digital models using GOM Inspect Professional software, while predicted tooth movement values were obtained from the ClearCorrect Doctor Portal. As the data were not normally distributed, comparisons between achieved and predicted movements were performed using the Mann–Whitney U test. Results Comparison of planned and achieved tooth movements demonstrated moderate to high accuracy for most linear and angular movements in both maxillary and mandibular teeth. In maxillary teeth, planned and achieved values were generally comparable across central incisors, lateral incisors, and canines; however, mesiodistal translation of maxillary lateral incisors showed a significantly lower accuracy compared with the planned movement. In mandibular teeth, most movement parameters showed no significant differences between planned and achieved values, except for intrusion in central incisors and extrusion in lateral incisors. Conclusions ClearCorrect aligners showed moderate to high accuracy for most angular and translational movements of anterior teeth, while vertical movements, particularly intrusion and extrusion, were less predictable. Canines exhibited the greatest biomechanical stability, whereas incisors were more susceptible to variability.
