Results : 1 ) under the same condition of loading , the stress and displacement of mesial occlusal rest design was smaller than that of distal occlusal rest design in abutment teeth and soft tissue under the base , however , the magnitude in the soft tissue under base was bigger . 2 ) when a distributed vertical load was applied to the artificial tooth abutment teeth regions , the stress distribution was similar to that of concentrated load in the artifitial tooth , and stress magnitudes were higher . 3 ) under the condition tested , the mesial occlusal rest design caused the stresses that were more in line with the long axes of the abutment teeth than did the distal occlusal rest design 結果: 1 )在同一加載條件下,近中(牙合)支托設計與遠中(牙合)支托設計相比,基牙及基托下軟組織的應力和位移值減小;基托下軟組織的應力和位移值大于基牙; 2 )基牙及義齒整體加載時,各基牙應力分布規律與人工牙加載相同,但應力值增大; 3 )近中(牙合)支托設計使基牙受力更趨于軸向。
