Purpose: The dental implant should be enough to endure chewing load and it’s required to have efficient design and use of implant to disperse the stress into bones properly. This study was to evaluate the stress distribution on a supporting bone by lengths and diameters of the implant fixture. Methods: The modeling and analysis of stress distribution was used for the simple molar porcelain crown model by Solidworks as FEM program. It was designed on applying with tightening torque of 20 Ncm of a abutment screw between a cement retained crown abutment and a fixture. The fixtures of experimental model used 10, 13㎜ by length and 4, 5㎜ by diameter. A external vertical loading on the two buccal cusps of crown and performed finite element analysis by 100 N. Results: The maximum von Mises stress(VMS) of all supporting bone models by fixture length and diameter were concentrated on the upper side of supporting compact bone. The maximum stress of each model under vertical load were 164.9 ㎫ of M410 model, and 141.2 ㎫ of M413 model, 54.3 ㎫ of M510 model, 53.6 ㎫ of M513 model. Conclusion: The stress reduction was increase of fixture’s diameter than it’s length. So it’s effective to use the wider fixture as possible to the conditions of supporting bone.
