Implant technology is no longer new and is being applied more and more frequently. One result of this development is the production of combined dentures, the denture mounted on implants or on a rail. Forces in the mouth are large and the chain is only as strong as the weakest link. Fracture is a logical consequence of the enormous forces acting on a cap denture. To address this annoying but well-known and logical situation, Vertex-Dental developed the high-impact material Vertex Implacryl.
