D6751 Dental Code: Crowns with High Noble Metal

Dental crowns are a cornerstone of restorative dentistry, offering both functional and aesthetic solutions for damaged or decayed teeth. Among the various types of crowns, those classified under the D6751 dental code stand out due to their use of high noble metal alloys, which provide exceptional durability and biocompatibility.

This comprehensive guide delves into every aspect of the D6751 dental code, from its clinical applications to insurance considerations. Whether you’re a dental professional seeking detailed insights or a patient exploring treatment options, this article provides an in-depth, well-researched, and engaging resource.

2. Understanding the D6751 Dental Code

Definition and Purpose

The D6751 code, as defined by the American Dental Association (ADA), refers to a crown restoration fabricated with high noble metal alloys. These alloys must contain at least 60% noble metals (gold, platinum, palladium) and at least 40% gold to qualify under this classification.

When Is It Used?

• Severely damaged teeth requiring strong reinforcement

• Molar restorations where chewing forces are highest

• Patients with metal allergies (due to high biocompatibility)

• Long-term durability needs (outlasts many other crown types)

3. High Noble Metal Alloys in Dentistry

Composition and Benefits

High noble metal crowns consist of:

• Gold (Au): Provides malleability and corrosion resistance.

• Platinum (Pt) / Palladium (Pd): Enhances strength and durability.

Comparison with Other Crown Materials

4. Clinical Applications of D6751

Ideal Candidates

• Patients with heavy occlusal forces (bruxism)

• Those needing long-lasting posterior crowns

• Individuals with nickel or base-metal allergies

Common Dental Conditions Treated

• Fractured teeth

• Large fillings requiring reinforcement

• Teeth after root canal treatment

5. The Procedure: Step-by-Step

1. Initial Consultation

   • Examination, X-rays, and treatment planning.

2. Tooth Preparation

   • Removal of decay and shaping the tooth.

3. Impression & Temporary Crown

   • Digital or traditional impressions sent to the lab.

4. Fabrication & Fitting

   • Custom crown is crafted and cemented permanently.

6. Advantages of High Noble Metal Crowns

✅ Superior longevity (20+ years with proper care)
✅ Minimal tooth removal required (conserves natural tooth structure)
✅ Highly biocompatible (rarely causes allergic reactions)

7. Disadvantages and Limitations

❌ Higher cost compared to base-metal crowns
❌ Metallic appearance (not ideal for visible teeth)
❌ Potential for galvanic reactions (rare)

8. Comparing D6751 with Other Crown Codes

• D6740 (Porcelain/Ceramic Crown): Better aesthetics but less durable for molars.

• D6780 (Noble Metal Crown): Lower gold content, slightly less expensive.

• D2790 (Full Cast Precious Metal): Similar but may have different alloy ratios.

9. Insurance and Cost Considerations

• Coverage: Many plans cover 50-80% of the cost.

• Average Cost: $1,000 – $1,500 per crown.

10. Maintenance and Long-Term Care

• Brush and floss regularly.

• Avoid chewing hard objects (ice, hard candy).

• Schedule biannual dental checkups.

12. Frequently Asked Questions (FAQs)

Q1: How long does a D6751 crown last?

A: With proper care, it can last 20-30 years or more.

Q2: Are high noble metal crowns safe for MRI scans?

A: Yes, they are generally safe but may cause minor artifacts.

Q3: Can a D6751 crown be used for front teeth?

A: It’s possible but not recommended due to its metallic appearance.

12. Conclusion

The D6751 dental code represents one of the most durable and biocompatible crown options available, ideal for posterior teeth requiring long-term strength. While it comes at a higher cost, its longevity and reliability make it a preferred choice for many patients and dentists.
