3D-CT assessment of mandibular widths in young subjects with different underlying vertical facial patterns

ConclusionsDolichofacials are likely to have relatively smaller masseter cross-sectional areas and volumes than brachyfacials, and vice versa. There is likely to be a close association between mandibular intermolar width and the corresponding widths at the apical and lower border levels. There is not likely to be the same association between the intercanine width and the corresponding lower border width. Brachyfacials are likely to have a greater width of buccal cancellous bone through which the canines can potentially be expanded laterally.
