  1. Surface area A: above coronoid process (CP) width line, surface area B: between incisura mandibulae—alveolar ridge line and width line, surface area C: between CP height and width, angle X: formed by lines placed tangentially to narrowest point of CP with common endpoint lying at highest CP point, angle Y: formed by one line stretched to lowest point of incisura mandibulae and other crossing point where line of width reaches CP anterior part.
