Background. The retromolar triangle (RT) and the mucous mandibular tubercle (MMT) are permanent anatomical landmarks for the removable prostheses of edentulous distal areas. Objective of the study. To study the available scientific literature and structural features of the mandibular retromolar region in cases with terminal defects or total edentation. Material and Methods. Were studied the literature data and features of the anatomy and morphology of the retromolar re-gion on plaster models and 10 anatomical specimens with subtotal or total edentation. Results. RT is a slight depression of a triangular shape, formed by the division of the temporal ridge of the mandible into buccal and lingual internal oblique line and limited mesially by the third molar. The base of the triangle is formed by compact bone resistant to atrophy (Naumovich S. A., 2012). RT often has no clear boundaries and shape, and the transverse dimensions, on average, vary from 5-6 mm to 8-9 mm, which depends on the structure of the anterior part of the temporal ridge, but not on the degree of atrophy of the alveolar process. Conclusion. Individual variations of the retromolar triangle anatomy have place; the posterior edge of the total prosthesis must cover the entire MMT and must end at the base of the pterygomandibular fold, providing the stability and functionality of the prosthesis. |
