D6792 Dental Code: Crown Repair – A Detailed Exploration

Dental crowns are a crucial restorative solution for damaged or weakened teeth, but even the most durable crowns may require repairs over time. The D6792 dental code is specifically designated for the repair of a prosthetic crown, addressing issues such as fractures, chipping, or debonding.

This comprehensive guide explores every aspect of the D6792 code, from its clinical applications to cost considerations, ensuring both dental professionals and patients understand its significance. Whether you’re a dentist looking to accurately bill for crown repairs or a patient curious about the process, this article provides in-depth insights.

2. Understanding the D6792 Dental Code

Definition and Purpose

The D6792 code falls under the American Dental Association’s (ADA) Code on Dental Procedures and Nomenclature and refers to the “repair of prosthetic crown”. Unlike a full crown replacement, this code applies when an existing crown is repaired rather than entirely remade.

When Is D6792 Used?

• Porcelain fractures (chipping or cracking of the ceramic layer)

• Exposed metal framework due to wear

• Loose crowns needing recementation

• Minor adjustments for better fit

This code is not used for complete crown replacements (which fall under codes like D2740 or D2750).

3. Types of Crown Repairs Covered Under D6792

Porcelain Fractures

Porcelain-fused-to-metal (PFM) or all-ceramic crowns may chip over time. Dentists use composite resin or porcelain repair kits to restore aesthetics and function.

Metal Framework Repairs

If the underlying metal structure is exposed, polishing or smoothing the area may be necessary.

Cementation Issues

A loose crown can often be repaired by cleaning and re-cementing it rather than fabricating a new one.

5. Clinical Procedures for Crown Repair (D6792)

Step-by-Step Process

1. Examination – Assess damage via X-rays or visual inspection.

2. Preparation – Remove debris and roughen the surface for bonding.

3. Bonding – Apply composite resin or dental adhesive.

4. Polishing – Smooth the repaired area for a natural look.

Materials Used

• Composite resin (tooth-colored filling material)

• Porcelain repair kits (for ceramic crowns)

• Dental cement (for recementation)

6. Cost and Insurance Considerations

• Average Cost: $150–$400 per repair (varies by location and complexity).

• Insurance Coverage: Many plans cover D6792 if the crown is otherwise functional.

7. Common Challenges in Crown Repairs

• Patient Discomfort: Sensitivity post-repair.

• Longevity: Repaired crowns may not last as long as new ones.

8. Preventive Measures to Avoid Crown Damage

• Avoid chewing hard foods (ice, nuts).

• Wear a nightguard if grinding teeth.

• Maintain good oral hygiene.

9. Case Studies

• Case 1: A 45-year-old patient with a chipped PFM crown successfully repaired with composite.

• Case 2: A debonded crown recemented, avoiding full replacement.

10. Future Trends in Crown Repairs

• 3D-printed repair solutions

• Stronger nano-ceramic materials

11. Conclusion

The D6792 dental code is essential for repairing damaged crowns efficiently and cost-effectively. Understanding its applications helps dentists provide optimal care while ensuring accurate billing. Patients benefit by preserving existing crowns instead of undergoing full replacements.
