Understanding Dental Code D6750: A Comprehensive Guide
What Is Dental Code D6750?
Dental Code D6750 is a billing code used in the American Dental Association’s (ADA) Current Dental Terminology (CDT) to describe a porcelain-fused-to-high-noble-metal crown. This type of dental crown is a hybrid restoration, combining the strength of a metal alloy (containing at least 60% noble metals like gold, platinum, or palladium) with the aesthetic appeal of porcelain.
Key Features of D6750 Crowns
-
Durability: The high-noble metal base provides long-lasting structural support.
-
Aesthetics: The outer porcelain layer mimics natural tooth color.
-
Biocompatibility: Noble metals are less likely to cause allergic reactions.
When Is D6750 Used?
Dentists recommend D6750 crowns in cases where both strength and aesthetics are required, such as:
-
Molars and premolars (due to high chewing forces)
-
Teeth with significant decay or fractures
-
Patients who want a natural-looking restoration
Contraindications
-
Patients with metal allergies (though rare with high-noble metals)
-
Front teeth where all-porcelain (e.g., D2740) may be preferred for better aesthetics
D6750 vs. Other Crown Codes
| Code | Description | Material | Best For |
|---|---|---|---|
| D6750 | Porcelain-fused-to-high-noble-metal | Porcelain + Gold/Palladium alloy | Molars, durability + aesthetics |
| D2740 | All-porcelain crown | Ceramic (e.g., zirconia) | Front teeth, best aesthetics |
| D2790 | Full cast high-noble metal crown | Solid gold alloy | High-stress areas, no aesthetics |
Materials Used in D6750 Crowns
The D6750 crown consists of two layers:
-
Inner Core: High-noble metal (≥60% gold, platinum, or palladium)
-
Outer Layer: Tooth-colored porcelain
Advantages of High-Noble Alloys
✔ Corrosion-resistant
✔ Less plaque accumulation than base metals
✔ Longer lifespan (15+ years with proper care)
