Abstract
Aim: The purpose of this study was to determine the mucosal thickness changes in two types of remov-able partial denture base materials (Cobalt Chrome and Flexible) wearers over a two months period. Materials and Methods: Six patients (three men and three women) were included in this study, old ages group was over 50 years. The partially edentulous patients were randomly chosen from the De-partment of Prosthodontics, College of dentistry, University of Mosul. The effect of wearing flexible and conventional cobalt chrome (Co-Cr) RPDs on the underlying mucosa were studied, special record base of visible light cured made for each patients with three holes were used to record clinical meas-urements using digital caliber and followed up for two months after insertion of denture. Results: The result of this study indicated that there are significant mucosal thickness changes in the central and lin-gual (palatal) positions of the Co-Cr RPDs groups; with no significant mucosal thickness changes in three holes of the Flexible RPDs groups. Conclusion: This study concluded that the flexible denture is a good optional treatment in removable prosthodontics management. Patient satisfactions with flexible removable partial denture during function were concluded according to patients remarks in relation to cobalt chrome (Co-Cr) removable prosthodontics type.
