2. What is Dental Code D2740?
Dental Code D2740 is a billing code used by dentists to describe a porcelain or ceramic crown restoration. The American Dental Association (ADA) assigns these codes to standardize dental procedures for insurance and record-keeping purposes.

-
Made entirely of porcelain or ceramic (no metal base).
-
Highly aesthetic, mimicking natural tooth color.
-
Ideal for front teeth and visible areas.
-
Biocompatible (less risk of allergic reactions).
Comparison of Common Crown Materials

|---|---|---|
| Porcelain/Ceramic (D2740) | Natural appearance, metal-free, biocompatible | Less durable than metal crowns, may wear opposing teeth |
| Porcelain-Fused-to-Metal (PFM) | Stronger than all-porcelain, good aesthetics | Dark gum line over time, metal may show |
| Gold Alloy | Extremely durable, gentle on opposing teeth | Highly visible, not aesthetic |
| Zirconia | Strong, tooth-colored, metal-free | Less translucent than porcelain |
