Values are presented as mean ± standard deviation.
One-way analysis of variance and post-hoc Tukey test were performed.
Different letters indicate statistically significant differences (Tukey tests).
IZC, infrazygomatic crest; MBS, mandibular buccal shelf; 6, the mandibular first molar; 7, the mandibular second molar; d, distal root projection; m, mesial root projection.
IZC 11, measurement of IZC thickness 11 mm above the buccal tip of maxiilary first molar; MBS 6d 4, distal root projection of the mandibular first molar at 4 mm below cementoenamel junction of mandibular first molar.
