ABSTRACT Objectives To analyze the mandibular retromolar space among normal-divergent adult patients with different sagittal skeletal patterns by cone-beam computed tomography (CBCT). Materials and Methods CBCTs of a total 120 were investigated. Patients categorized into following three groups according to their ANB angle: Class I (48 patients), II (36 III patients). Four planes parallel occlusal plane used measure space. The was measured two reference lines then compared between groups. incidence root contact inner lingual cortex Results significantly larger than that patients. Compared patients, had smaller higher mandible. Conclusions in four planes. should be evaluated CBCT who need molar distalization.
