- Title
Metal Substructures for Metal-Ceramic Restorations.
- Authors
Miller, Lloyd L.
- Abstract
The article presents a research which examines several principles, including rigidity of support, marginal integrity, and access for maintenance, which should be considered before designing metal substructures for metal-ceramic restorations. One of the principles, as reported, called rigidity of support has 2 applications which requires consideration. One, as reported, is that the metal substrate must be firm and unyielding to preserve precise abutment metal form while the porcelain is being fired, and the other is that the frameworks for fixed partial prosthodontics should have metal structures which can withstand the forces of sintering shrinkage, and the functional and parafunctional forces of occlusion without fatigue or deflection beyond the limits of the porcelain or metal.
