Reinforced porcelain system. Concepts and techniques

The RPS approach to ceramometal restorations provides guidelines for the design of metal interstructure for crowns and pontics and for the desired qualities of the ceramometal interface. The metal design increases porcelain fracture resistance to impact and pressure and creates a ceramometal mutual reinforcement of the whole restoration. A secure bond and porcelain protection at the interface can be achieved through intermediate zone materials.
