Porcelain-Bonded Restorations: Designs and Principles
Cherilyn G. Sheets, DDS
Porcelain-bonded restorations (PBRs) have radically changed the way that dentists diagnose and devise treatment plans for patients. The option of having a minimally invasive, yet strong and aesthetically pleasing, restoration has numerous advantages for patients in both the short- and long-term life expectancy of their restorations. The ability to make aesthetic and functional enhancments without compromising the biological health of periodontal or pulpal tissues is powerful. This podcast reviews the fundamental requirements of tooth preparations for porcelain veneers for predictable restoration in both the anterior and posterior regions.
