COMPARATIVE EVALUATION OF THE INFLUENCE OF VARIOUS DESIGNS OF REMOVABLE DENTURES ON THE PROSTHETIC BED IN CASE OF PARTIAL ABSENCE OF TEETH

Partial absence of teeth is one of the most common pathologies of the dentition. To replace defects in the dentition in orthopedic dentistry, various designs of removable dentures are often used (S.A. Ponomarev, 2004; V.V. Brovko, Yu.V. Kresnikova , A.Yu. Maly, 2007; Yu.V. Kresnikova , 2008 ; A.B. Onufriev , 2009). Removable plate and clasp dentures are used to restore the integrity of the dentition . A distinctive feature of clasp prostheses is the transfer of most of the masticatory pressure on the abutment teeth through a system of support-retaining clasps . Lamellar prostheses transfer most of the load to the mucous membrane and bone tissue compared to clasp prostheses (G.P. Sosnin, 1981; A.P. Perevezentsev , 2002). This effect is not a physiological factor for these tissues
