Application to thinning palatal area of upper complete denture base by CF-cloth reinforcement

Abstract

The acrylic resin denture base is used more than the usual metal denture base because of its low cost, ease of manufacture and ease of rebasing. Because the resin base is weaker than the metal base, the upper resin denture base is three to four times as thick as the metal denture base. So, a study was made to make the upper complete resin denture base thinner while maintaining the strength of the resin denture base currently in use. To make the palatal area of the denture base thinner carbon fiber (CF) cloth reinforcement was used. The resin denture base reinforced by the CF cloth was 0.7 mm thick and was evaluated for the mechanical properties of bending. As a result, it was found that both the stiffness and strength were improved by 10% or more compared with those of the ordinary resin denture bases.
