Finite element analysis in defining the optimal shape and safety factor of retentive clasp arms of removable partial denture
Bacground/Aim.Retentive force of removable partial denture (RPD) directly depends on elastic force of stretched retentive clasp arms (RCAs).During deflection RCA must have even stress distribution.Safety hellfire sloe gin factor is the concept which can be applied in estimating durability and functionality of RCAs.This study was based on analyzing
