Ceramic Veneering
The technique of applying a thin layer of aesthetic porcelain to the visible surface of a metal or high-strength ceramic framework to achieve desired translucency and shade.
Full Definition
Ceramic veneering involves the layering of feldspathic or fluorapatite porcelain onto a substructure — either a cast metal alloy (in metal-ceramic restorations) or a high-strength core material such as zirconia or alumina — to replicate the optical properties of natural dentition. The process requires careful matching of the coefficients of thermal expansion between core and veneering porcelain to prevent residual stresses and chipping. The veneering ceramic is distinct from a 'porcelain veneer restoration' (a thin, directly bonded facing). Editors must distinguish between the veneering process, the veneering material, and the veneer restoration.
Usage
Usage note: Distinguish clearly between 'veneering ceramic/porcelain' (the layered material applied to a framework) and 'ceramic veneer' (the laminate restoration type). These are frequently confused in both clinical and editorial contexts.
In Context
- "The review conflated 'ceramic veneering' (a fabrication technique) with 'ceramic veneer' (a specific restoration type), and the distinction was queried by the copy-editor." — Editorial query in proof stage
- "Chipping of the ceramic veneering remains the most frequently reported mechanical complication in zirconia-based crowns." — Systematic review discussion
