What distinguishes a three-quarter crown from a full crown?

It covers the entire tooth surface
It leaves the facial surface of the tooth intact
It is made solely of porcelain
It is removable by the patient

The correct answer is: It leaves the facial surface of the tooth intact

A three-quarter crown is designed to cover most of the tooth except for a portion of its facial surface. This means that while it provides extensive coverage to protect and strengthen the remaining tooth structure, it does not completely envelop the tooth, allowing the face of the tooth to remain intact and visible. This can be particularly beneficial in aesthetic areas of the mouth, where maintaining a natural appearance is important. The other options describe features more characteristic of full crowns or do not accurately reflect the nature of a three-quarter crown. A full crown covers the entire tooth surface, while options about materials or removability pertain to other types of dental restorations and their specific characteristics rather than distinguishing features of a three-quarter crown.
