[Research of chewing efficiency in patients with extensive acquired defects of the upper jaw after resections of nasopharyngeal zone tumors and various terms of orthopedic rehabilitation].

The aim of the study was to estimate how the quality and terms of rational dental orthopedic treatment affects masticatory efficiency in patients using obturators after extensive resections of nasopharyngeal area tumors. The analysis of indicators of masticatory efficiency in dynamics with the use of masticatory probe of V.N. Trezubov considering prosthetics terms, functional and age features was conducted in 14 patients. The results of the research show that high-quality substitution of obturating structures positively affects masticatory efficiency dynamics and therefore has positive impact on the general health state and also on the level of physical and psychological comfort of patients.
