Introduction: The objective of this study was to compare the locations of the centers of resistance (CRes) in the buccolingual (BL) and mesiodistal (MD) directions of the mandibular central incisors of 6 dogs. Methods: Based on microcomputed tomography images of the teeth and their supporting tissues, solid models were used to build finite element models. Results: The CRes locations for the 6 specimens were determined for displacements in the BL and MD directions with finite element calculations. Measured from the alveolar crest, the BL and MD locations were 43% to 51% and 31% to 43% of root length, respectively. Their average locations, 46.2% and 38.3%, were statistically different at the 95% CI. Conclusions: The CRes location for BL tooth movement is significantly more apical than its MD counterpart.
