A Novel Method to Quantify Longitudinal Orthodontic Bone Changes with In Vivo Micro-CT Data

The reconstruction, partition, and extraction of the alveolar bone around the mesial root: (a) the reconstruction of the crown and mesial root of the upper first molar; (b) generation of the cylinder around the root; (c) partition of the cylinder with the alveolar crest plane; (d) division of the cylinder into the mesial and distal sides according to the direction of the orthodontic load; (e) reconstruction of the alveolar bone within semicylinder filters.
