ABSTRACT Objectives: To investigate the retromolar space available for molar distalization in patients with mandibular prognathism. Materials and Methods: Using cone-beam computed tomography, the posterior mandibular dimensions in 110 consecutive patients with Class I or Class III malocclusion were measured (mean age, 27.0 ± 7.1 years). The shortest linear distances from the distal root of the right mandibular second molar to the inner border of the mandibular cortex were measured at the level of root furcation and 2, 4, and 6 mm apical to the furcation along the sagittal line and the posterior line of occlusion. The retromolar distances were compared between the Class I and Class III malocclusion groups using general linear mixed models. Results: The retromolar space measured through the sagittal line showed no significant intergroup difference. Among the distances measured through the posterior line of occlusion, the space measured at depths 0 and 2 mm to the furcation were significantly greater in the Class III group than in the Class I group. Conclusions: Patients with Class III malocclusion have greater retromolar space for mandibular molar distalization along the posterior line of occlusion only at the level of the second molar furcation.

Molar distalization is considered as a good approach for creating space. Conventional methods were depended on patient compliance but with se of mini screw, tooth movement are done more rapidly, easily and non-compliance. Our design is useful for unilateral upper molar distalization by modified power arm that is connected to mini screw by elastic chain.
