Metal-ceramics - Back to the future or last man standing!

Learning objectives. 

1. The literature reporting long-term outcomes of dental prostheses is often lacking, confusing or deceptive.

2. Metal-ceramic prostheses have unparalleled long-term clinical outcomes.

3. Practice-based clinicians have an ethical dilemma concerning when to embrace new materials and     techniques.

Abstract

New techniques and materials for fabrication of tooth- and implant-supported single unit crowns and FDPs have proliferated over the last few years. But are the claimed biological, mechanical, aesthetic and economic advantages real, or driven by vested interests and convenience. Does the science live up to the hype? The ethical dilemma  for the practice-based clinician, in this age of evidence-based treatments, is when to embrace the new and discard the old, especially when the supporting science is lacking, confusing or even deceptive. Where is the ethical/unethical divide? Is there still a place for metal- ceramics or are they ?old school? and will they go the same way as the acrylic-veneered metal constructions?  Is it a case of ?last man standing? to claim that metal-ceramic restorations remain the ?gold standard? for indirect prostheses?
