The present invention relates to a combination of configurations for copings and for the fiber bar for manufacturing a dental prosthesis framework, and describes a method for obtaining a dental prosthesis framework using one of the described copings and the fiber bar. The configuration feature applied to the coping is that of providing at least one incorporated hook to accommodate the fiber bar, withstand the stress on the framework and contribute to the adhesiveness of the fiber bar to the coping, also aiding in maintaining the molded shape of the bar whilst it hasn't polymerized. The feature of the fiber bar is that it can be produced from a bundle of parallel fibers that are longitudinally aligned, non-fragmented and covered by a woven glass-fiber jacket, there also optionally being a seam to ensure a flattened cross section.
Configurations applied in copings and fiber bars for manufacturing fixed dental prosthesis frameworks and method of obtaining the referred frameworks using these configurations of copings and fiber bars, refers to a set of constructive configurations of dental copings, and means of obtaining the fiber bars for the manufacture of dental prosthesis frameworks formed by referred coping, referred fiber bar and for a photopolymerizable polymeric material, being fiber bar comprised of a fiberglass impregnated with a resinous composition, and the copings can be screwed, cemented or for attachment, where in the copings provides at least one hook incorporated, with a compatible configuration to receive the fiber bar impregnated with the resin composition, and the photopolymerizable polymeric material;
Method of obtaining the referred frameworks using these configurations of copings and end fiber bar comprising:
