ABSTRACT
OBJECTIVE:
To assess the accuracy of anterior tooth movement using clear aligners in integrated three-dimensional digital models.METHODS:
Cone-beam computed tomography was performed before and after treatment with clear aligners in 32 patients. Plaster casts were laser-scanned for virtual setup and aligner fabrication. Differences in predicted and achieved root and crown positions of anterior teeth were compared on superimposed maxillofacial digital images and virtual models and analyzed by Student's t-test.RESULTS:
The mean discrepancies in maxillary and mandibular crown positions were 0.376 +/- 0.041 mm and 0.398 +/- 0.037 mm, respectively. Maxillary and mandibular root positions differed by 2.062 +/- 0.128 mm and 1.941 +/- 0.154 mm, respectively.CONCLUSIONS:
Crowns but not roots of anterior teeth can be moved to designated positions using clear aligners, because these appliances cause tooth movement by tilting motion.
