Fig. 1From: Prevalence and correlation with sex, age, and dental status of bone apposition at the mandibular angle and radiographic alterations of the temporomandibular joints: a retrospective observational study in an adult Swiss populationRadiological evaluation of bone apposition at the mandibular angle and grade classification: A and B are categorized as “no alteration”. A shows the natural convexity of the mandibular contour without directional deviation, B describes a standard variant of the mandibular angle with directional deviation but without bone apposition. C and D show examples of bone apposition in combination with directional deviation (here: generalized apposition with inhomogeneous surface (C) and localized spike-shaped apposition at one or more sites (D))Back to article page
