Research Abstract	Finite element analysis(FEA) was carried out for the Butt Joint type implant with the external hexagon(EXT) and an internal hexagon(INT) configuration for abutment connection to confirm the platform switching(PLS) effect. PLS which sets a horizontal gap to abutment and an implant junction, when the edge portion of abutment is located inside a platform, the distributed tendency of stress is changed. The results of FEA(both EXT and INT configuration) demonstrated that PLS the stress concentration in an implant neck assembly is reduced.
