Implant-supported braced dental bridge armature made from composite material, and method for manufacturing the armature

摘要

A dental bridge armature designed to be screw-fastened onto dental implants, the dental bridge armature having reinforcing elements formed by long fibers pre-impregnated with photo-polymerizable resin which are either woven or in bundles. The reinforcing elements are in the form of a fibrous framework including a main brace and base reinforcing elements wound around a series of implant abutments screwed onto the implants. Secondary braces are also wound around the main brace and the base reinforcing elements. The braces form an angle between 15° and 85° with the base reinforcing elements. The armature is then included in a PMMA coating resin by a pressing or injection technique.

1. A dental bridge armature designed to be screw-fastened onto dental implants, said armature being made from composite constituted by fibres and particles, and filled with resin by deposition, pressing or injection,
said armature comprising:
reinforcing elements formed by long fibres pre-impregnated with photo-polymerizable resin which are either woven or in bundles, said reinforcing elements being in the form of a fibrous framework, comprising a main brace and base reinforcing elements, all wound around a series of implant abutments screw-fastened onto the implants, and the ends of the main brace are inclined in the direction of the base reinforcing elements,a first reinforcing element being wound around the implant abutments in a clock-wise direction, anda second reinforcing element being wound around the implant abutments in a counter-clockwise direction, wherein the main brace and the base reinforcing elements are wound around the implant abutments at different heights of the implant abutments so as to form a three-dimensional structure.
