Landmark predictions in the sagittal (left) and coronal (right) planes (a–d). The predicted and ground truth landmarks are represented as red and green dots, respectively. (a) The best case with the least errors and (d) the worst case with the most errors. (A) Maxillary sinus floor; (B) alveolar bone crest; (C) adjacent cementoenamel junction; (D) medial point of horizontal bone width; (E) lateral point of horizontal bone width.
