Currently, manufacturing techniques for removable orthopedic structures made of thermoplastic materials are widely used. Objective. To determine the clinical effectiveness of orthopedic treatment of dentition defects with arch prostheses with a framework made of polyoxymethylene using a modified design of supporting metal-ceramic crowns. Using clinical methods, 76 patients with defects in the dentition were examined, who underwent orthopedic treatment with arch prostheses with a frame made of metal and polyoxymethylene. As a result of the study, the clinical efficacy of using the proposed design of a metal-ceramic crown for a support-retaining clasp made of polyoxymethylene and a method for creating a retention zone in a ceramic-metal crown is proved.
