HOSA Dental Terminology Practice

What does PFM stand for in dental terminology?

1. Porcelain fused to metal crown

2. Partial full metal restoration

3. Porous filling material

4. Plastic fused to metal

The correct answer is: Porcelain fused to metal crown

PFM stands for porcelain fused to metal crown. This term describes a type of dental crown that combines both porcelain and metal to create a restoration that is both aesthetically appealing and structurally strong. The metal base provides durability and strength, while the porcelain overlay mimics the natural appearance of tooth enamel, making it a popular choice for visible teeth. The fusion of these materials allows for a reliable solution for restoring damaged teeth, particularly in cases where strength is a significant concern. Other options, while they may contain dental terminology, do not accurately represent the established meaning of the acronym PFM in dentistry. For instance, partial full metal restoration and porous filling material imply different types of dental work that do not combine porcelain and metal in the way PFM does. Likewise, plastic fused to metal is not a recognized term in dental practice, as it does not possess the same benefits and uses as porcelain fused to metal crowns. Thus, understanding PFM as porcelain fused to metal crown provides insight into restoration options that balance aesthetics and functionality.
