A = Upper jaw first right molar EJS on CBCT cross-sectional image is more than 10 mm in height and classified as Type I with no requirement of vertical alveolar process bone height augmentation prior endosseous dental implant treatment (all CBCT images in this article were obtained with I-CAT^® (Imaging Sciences International LLC, Hatfield, PA USA) CBCT, a letter "b" on cross-sectional CBCT image means buccal side).
B = Type I height (> 10 mm) of lower jaw first left molar EJS on CBCT cross-sectional image.
C = Type II height (> 8 to ≤ 10 mm) of lower right first molar EJS on CBCT cross-sectional image. Simultaneous implantation with sinus floor augmentation are recommended.
D = Type II height (> 4 to ≤ 10 mm) of upper right first molar EJS on CBCT cross-sectional image. Simultaneous implantation with vertical alveolar process augmentation are recommended.
E = Type III height (≤ 8 mm) of lower left second molar EJS on CBCT cross-sectional image. Vertical alveolar process augmentation and late implantation are recommended. Mandibular canal walls have proper identification with D2 bone quality.
F = Type III height (≤ 4 mm) of upper left premolar EJS on CBCT cross-sectional image. Sinus floor augmentation and late implantation are recommended.
