Figure 1. A, Cone-beam computed tomography (CBCT) image cut at levels C5, C10, C15, C20, C25, and C30. Mandibular CBCT images are digitally cut into 5-mm-thick sections parallel to the mandibular plane. B, The thickness and crosssectional area of the masseter muscle at each cut level. The arrows indicate the maximum thickness of the masseter muscles, and the indicated areas represent the cross-sectional area of the masseter muscles.
