Question

A 25-year old fashion model has large mesial and distal class 3 composites on tooth #8, which have turned brown; the composites are visible when she smiles. She wants to get rid of the composites and the discoloration. The dentist has recommended a porcelain-fused-to-metal crown. The fashion model wants an all-porcelain crown to maximize the esthetics. What are the pros and cons of each type of crown for this application? if an all-ceramic crown is done, what type of ceramic material is best for this application? Should the crown be bonded or just cemented? Why?
