Abstract

The occlusal stress distribution and displacement of model in a supported tooth were examined.<BR>The effects of presence or absence of the bound saddle on the residual ridge and the rigidity of the removable bridge were evaluated by 2-dimensional finite element method.<BR>The results were as follows:<BR>1. Stress distribution on the abutment teeth under loading was more dispersed in the plate type removable bridge than in the non-plate type removable bridge. This finding was observed more markedly in canine abutment than in that of the second molar.<BR>2. Displacement of the node of the removable bridge under loading was decreased in the plate type removable bridge than in the nonplated type removable bridge.<BR>3. Irrespective of the presence or absence of the plate, the stress distribution in the abutment teeth under loading was more dispersed in the removable bridge made of metal with high Young's modulus than in the bridge with low Young's modulus.<BR>4. Irrespective of the presence or absence of the plate, displacement of the node of the removable bridge under loading was more decreased using the removable bridge made of metal with high Young's modulus than in the bridge with low Young's modulus.
