Popis:	We have developed structural designs of three dimensional framework from a usual metal plate.The framework consisting of double structure was representative of the structural designs, with the intention of improved mechanical strength and durability.The purpose of this study was to investigate the effect of different structural designs on torsion strength by statical bending test, and to compare torsion stiffness of extension base removable partial denture by loading test on the simulation model.The results obtained were as follows:1. Torsion strength of the double structure was approximately 10 times that of skeleton types, and torsion stiffness was about 3 times.2. When torsion moment was applied, principal strain of the skeleton types increased remarkably, but the double structure did not show significant change.3. Distal displacement of the double structure increased approximately 20 μm by changing the loading point, but skeleton types increased 80-100 μm.
