What classification does a PFM crown fall under?

Aesthetic restoration
Functional restoration
Implant restoration
Orthodontic device

The correct answer is: Aesthetic restoration

A PFM (porcelain-fused-to-metal) crown falls under the classification of an aesthetic restoration. This type of crown is designed to restore a tooth while providing a more natural appearance compared to a metal-only crown. The porcelain component allows for a color and translucency that mimics natural tooth enamel, making it aesthetically appealing, especially for visible teeth. While the metal base offers strength and durability, the aesthetic factor is a primary reason for their use in restorative dentistry. This crown is commonly chosen for areas where both functionality and appearance are important, such as in front teeth and premolars. The ability to blend seamlessly with the surrounding natural teeth highlights the importance of aesthetic restorations in cosmetic dentistry, making PFM crowns a popular choice. In contrast, functional restorations focus more on restoring the normal function of the teeth, implant restorations are related to replacing missing teeth with implants, and orthodontic devices are used for the alignment and positioning of teeth rather than direct restoration.
