Assessment of metabolic changes in patients with heterogeneous metal orthopedic structures after dental-maxillary prosthetics

Abstract

Improving dental technology requires reassessment of the use of old materials for treatment and prosthetics. Heterogeneous metal orthopedic structures in tooth-jaw prosthetics may induce local reactions to metals and dermatitis associated with microcurrents. Aim. To evaluate the nature and severity of metabolic changes in the oral cavity and their relationship with the materials used for prosthetics. Methods. The study involved 133 patients older than 60 who were conventionally divided into 4 groups based on the presence or absence of metal / plastic structures. Subfractional composition of oropharyngeal washouts was studied using an LCS-03 laser correlation spectrometer (Intox, Russia). Results. Prosthetics with a single metal increases the incidence of intoxication-like changes whereas using two metals increases allergic and dystrophic-like disorders, which was not observed in using plastics.
