  • Publication number: 20220175496
    Abstract: 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.

  • Patent number: 10456220
    Abstract: A bendable prosthetic abutment includes a guiding and anchoring segment, a connection zone, for connecting to an implant arranged on a gingival tissue for receiving a prosthetic abutment model, an intermediate restriction for angular orientation, a mounting and fastening portion forming an upper portion of the bondable prosthetic abutment for receiving a prosthesis, and a sacrificial and anchoring zone which has a diameter greater than a diameter of the connection zone so as to define a protuberant ring-shaped shoulder arranged between the intermediate restriction (4) and the connection zone (2) for connecting to an implant and anchoring in a cavity.

  • Publication number: 20150173863
    Abstract: The present invention relates to a definitive and bendable prosthetic abutment and the corresponding angular adjustment method, belonging to the field of implant dentistry, the method being in particular characterized by a customized mechanical forming process that helps dental surgeons and/or dental prosthesis technologists to orient the exposed part of the abutment with an inclination angle that makes it easier to mount the future prosthetic crown. In a particular embodiment, a definitive prosthetic abutment model comprises a guiding and anchoring segment (1) followed by a zone (2) for connection to an implant, comprising a sacrificial and anchoring zone (3) followed by a restriction (4) in the lower third to achieve angular adjustment; and adjoining the latter a mounting and fastening portion (5) for a prosthesis (not depicted).
