Question

Quizplus · Accepted Answer

The tapered margin preparation for crown placement is called a chamfer. A chamfer is a beveled edge or a sloping edge that is made to reduce the sharpness of the corner. A chamfer is commonly used in dental procedures including crown preparations. A shoulder preparation is a more extreme version of a chamfer where the tooth structure is more aggressively removed to create a clear margin for the crown. A bevel preparation involves creating an angle or slope similar to a chamfer but the purpose is typically for better bonding of filling materials rather than crown placement. A coping is a dental laboratory term that refers to the underlying structure of a crown, which is typically made of metal or zirconia.
