Enamel erosion does not involve bacteria. Tightening the remaining retaining screws in an ill-fitting metal substructure will cause unwanted strain to the supporting implants. Frameworks with porcelain can be spark eroded without any stress on the porcelain due to the cooling action of the di-electric fluid. *FREE* shipping on qualifying offers. In some fully implant-supported fixed denture designs, porcelain is applied to the metal substructure. Use a custom tray and a rigid impression material such as polyether to make the final master impression (.
