A polymer crown is characterized by which of the following?

A polymer crown is primarily made from materials such as composite resin, which is known for its aesthetic properties and ability to be color-matched to natural teeth. This characteristic ensures that the crown blends well with the surrounding teeth, making it a preferred option for visible areas in the mouth.

Composite resin crowns are designed to provide a good balance between strength and aesthetic appeal. They may not necessarily require multiple visits for completion, as some types of composite crowns can be fabricated directly in the dental office and placed in a single appointment, unlike more complex restorations that might need laboratory involvement. While it may be true that some crowns are intended for temporary use, polymer crowns can also be used for long-term solutions in cases where appearance is a high priority.

The focus on composite resin filling accurately reflects the composition and utility of a polymer crown in restorative dentistry, thus reinforcing the understanding of materials used in dental restoration.
