The use of current dental materials can produce highly esthetic results while minimizing the amount of tooth reduction. Historically, full metal crowns offered longevity but full gold metal display is unacceptable for most patients today. Porcelain fused to metal restorations is more esthetic but require significantly more tooth reduction to accommodate two materials. Moreover, have risk of porcelain separation from metal and potential for metal display (black margin). All porcelain restorations are beautifully esthetic but have increased risk for fracture in the posterior of the mouth. Ask us about zirconia.
