A procedure for fabricating an individual abutment for a dental prosthesis for an implant anchored in an area of the jaw with an implant attachment running on the abutment side, using a working model molded by the jaw area equipped with the implant. The sulcus area of the gum uncovered above the implant and shaped by a sulcus-former extending from the implant attachment is reproduced in the working model. The abutment has a sulcus section running within the sulcus area and an adjoining head section to admit a part of a dental prosthesis. The sulcus area of the working model having an auxiliary implant attachment corresponding to the implant attachment is measured, and a sulcus section model determined with a circumferential surface and a de-facto sulcus line limiting it on the implant side.

Method for fabricating an abutment

A process for preparing grit blasting particles coated with titanium dioxide by sinter-fusing titanium dioxide on the surface of grit blasting particles made of a base material. A mixture of finely divided titanium dioxide and grit blasting particles is passed continuously through the flame in a flame reactor, with the aid of conveying air, wherein the titanium dioxide is sinter-fused on the surface of the grit blasting particles over an average residence time of 0.1 to 5 seconds in a temperature range from 600 to 1200&deg; C. An increase in the adhesive bond between metal framework and a facing material made of plastics in dentures can be achieved when metal framework is grit blasted with a grit blasting agent containing titanium dioxide coated grit blasting particles and then the grit blasted and titanium dioxide coated surface is treated with a silane bonding agent.

With a view to increasing the lifespan of metallic dental components as regards fatigue fractures, compressive stresses are introduced into the surface layer of these components, such as by means of shot-peening.
