LATE RESULTS OF PATIENTS’ ORTHOPEDIC TREATMENT USING FIXED PARTIAL DENTURES, DEPENDING ON THE FUNCTIONAL STATE OF THE ABUTMENT TEETH

Treatment of partial adentia involves preparation of abutment teeth, followed by the production of fixed partial dentures. However, the abutment tooth vitality should be taken into account and the periodontal reserve power should be considered to prevent functional overload. The hygienic condition of the oral cavity is also necessary to be monitored during treatment and at different times after it. Using clinical indices data, the preservation of vital teeth was found to be a more reliable criterion of effective use of fixed partial dentures than nonvital teeth. The Russel index demonstrated the absence of periapical injuries in vital teeth occuring in nonvital teeth because of neurovascular bundle extirpation. Other indexes showed irritation and bleeding of mucous membrane as a result of rubber dam use due to the necessity of qualitative endodontic treatment. The data obtained as a result of complex hygienic indices showed the advantages of preserving of abutment tooth vitality during the manufacturing of fixed partial dentures.
