WITHDRAWN: In vivo micro-computed tomography evaluation of BoneCeramic grafted alveolar defects during orthodontic tooth movement

Objective: To investigate three-dimensional microarchitecture and micromechanical properties of alveolar bone in the BoneCeramic grafting sites during orthodontic tooth movement. Materials and Methods: Sixty 5-week-old rats were randomly assigned into three groups to receive BoneCeramic, natural bovine cancellous bone particles (Bio-Oss), and no graft, respectively, after the extraction of the left maxillary first molar. After 4 weeks, the maxillary left second molar was moved into the extraction site for 28 days. Dynamic bone microstructures were evaluated using in vivo micro–computed tomography. Micromechanical properties and stress distribution of corresponding tissue were examined by nanoindentation and finite element methods. Mixed-model analysis of variance was performed to compare the difference among time points with Bonferroni post hoc tests at the significance level of P < .05. Results: The BoneCeramic group had the least amount of tooth movement and the highest bone volume fraction, tr...
