Fig. 2

In the coronal view, the reference lines are represented by VDB: vertical dental axis (yellow line) and CEJ: cementoenamel junction (green line). The measurements represented by ABT are the alveolar bone thickness at S1 and S2 (A) P3 and P6 represent the palatal side 3- and 6-mm distance from the CEJ in the apical direction. (B) B3 and B6 represent the buccal side 3- and 6-mm distance from the CEJ in the apical direction (red color) and root length: the distance between the constructed CEJ line and the root?s most apical point (red line)
