Abstract: The present invention provides methods allowing the use of selective laser powder processing techniques for the production of medically acceptable prosthetic dental frameworks. The frameworks produced according to the present invention have high grade mechanical properties as well as a high accuracy.

Abstract: To provide a dental abutment which is strongly adhered with a gingiva, can prevent invasion of bacteria into the jawbone, and hardly causes bone resorption and soft tissue shrinkage, a dental abutment (1) being fixed on the oral cavity inner side of a dental implant fixture (F) to penetrate a gingiva and becoming a base of a dental prosthesis (P) is structured such that a spiral projection or a plurality of ring-like projections having approximately equal intervals are formed along a circumferential direction on an outer periphery of the dental abutment contacting with the gingiva, and the projection has a width of 1 to 500 ?m and a height of 1 to 500 ?m.
