FRICTIONAL ABUTMENT HAVING ENHANCED FRICTIONAL FORCE

摘要

PURPOSE: A frictional abutment having enhanced frictional force is provided to generate strong frictional force when being separated. CONSTITUTION: A frictional abutment having enhanced frictional force comprises: a prosthesis joint(110) which is combined with a prosthesis by cement; an implant joint(120) which is combined with an implant and in which frictional grooves are formed in the inner surface thereof in order to enhance frictional combining power with an implant; a gum contact unit(130) which is prepared around the implant joint; and a position determining projection which is combined with a projection combination groove formed in the implant joint.
