    Dentistry uses fixed prostheses as a tertiary prevention. Prostheses in the oral cavity are foreign bodies. Therefore, they lead to a violation of the biological balance. It can cause complications during treatment. The purpose of the work was to determine the influence of galvanism on the composition of the microbiocenosis of the oral cavity in patients who used orthopaedic structures made of different materials, depending on the design features of the prosthesis. An examination of 81 persons who were prosthetics with fixed structures was carried out. They determined the composition of periodontal plaque bacteria. A plaque sample was taken from the surface of the cervical area of the vestibular surface of orthopaedic structures (crowns) close to the gingival margin (without touching or injuring it) on the maxilla and mandible to do this. The multiplex polymerase chain reaction method was used in real-time to determine microflora's bacterial mass and quantitative ratios. Biopotentials of the oral cavity were also determined. The potential difference was evaluated between the extreme points of the metal prosthesis (metal-metal) and the metal inclusion and the mucous membrane of the oral cavity. The presence of galvanism was established in all patients with fixed orthopaedic structures. It was determined that individual representatives of the microflora have different sensitivities to changes in the electrical potential of the oral cavity. The microbiome as a whole is a stable entity with a certain homeostasis. These phenomena should be considered when conducting orthopaedic treatment and recommending the patient's hygiene after orthopaedic treatment.
