D6242 Dental Code: Pontic – Porcelain Fused to High Noble Metal

The D6242 dental code refers to a pontic (artificial tooth) made of porcelain fused to a high noble metal alloy, used in fixed partial dentures (dental bridges). This code is essential for dental billing and insurance claims, ensuring standardized documentation across dental practices.

Pontics are crucial for replacing missing teeth, restoring function, and improving aesthetics. The D6242 code specifically applies to high noble metal-based pontics, which contain at least 60% noble metals (gold, platinum, palladium) and offer superior durability and biocompatibility compared to base-metal alternatives.

This guide explores everything you need to know about D6242 dental code, including its benefits, procedure, costs, and comparisons with other pontic options.

2. Understanding Dental Pontics and Their Role in Restorative Dentistry

A pontic is an artificial tooth that replaces a missing natural tooth in a dental bridge. Unlike removable dentures, pontics are permanently fixed to adjacent teeth (abutments) or dental implants.

Types of Pontic Designs

The D6242 code applies to pontics with a porcelain exterior fused to a high noble metal framework, combining strength and aesthetics.

3. What Makes D6242 Different from Other Pontic Codes?

The American Dental Association (ADA) categorizes pontic codes based on materials:

• D6240 – Porcelain fused to predominantly base metal

• D6241 – Porcelain fused to noble metal (at least 25% noble content)

• D6242 – Porcelain fused to high noble metal (≥60% noble metals)

• D6245 – Full cast high noble metal

Why choose D6242?
✔ Superior biocompatibility (less allergic reactions)
✔ Higher strength and longevity
✔ Excellent porcelain bonding for natural aesthetics

4. Materials Used in D6242: Porcelain Fused to High Noble Metal

High Noble Metal Composition

• Gold (Au) – Enhances durability and corrosion resistance

• Platinum (Pt) – Increases strength

• Palladium (Pd) – Improves alloy stability

Porcelain Layer Benefits

• Mimics natural tooth translucency

• Stain-resistant

• Custom-shaded to match adjacent teeth

5. Clinical Applications of D6242

D6242 pontics are ideal for:
✅ Replacing anterior (front) teeth where aesthetics matter
✅ Patients with metal allergies (high noble metals are hypoallergenic)
✅ Long-span bridges requiring extra strength

6. Step-by-Step Procedure for Placing a D6242 Pontic

1. Tooth Preparation – Abutment teeth are reshaped to hold crowns.

2. Impressions – A mold is taken for the dental lab.

3. Temporary Bridge Placement – Protects prepared teeth while the permanent bridge is fabricated.

4. Fabrication – The lab creates a high noble metal framework layered with porcelain.

5. Final Cementation – The permanent bridge is bonded into place.

7. Advantages and Disadvantages of D6242

Pros

✔ Long-lasting (15-20+ years with proper care)
✔ Highly aesthetic (porcelain mimics natural teeth)
✔ Biocompatible (less risk of gum irritation)

Cons

❌ Higher cost than base-metal alternatives
❌ Requires significant tooth reduction for abutments

8. Cost and Insurance Considerations for D6242

• Average Cost: $1,200 – $2,500 per pontic

• Insurance Coverage: Many plans cover 50-80% of the cost, considering it a “high noble” restoration.

9. Common Patient Questions About D6242

• “Is a D6242 pontic worth the cost?” – Yes, for long-term durability.

• “Will it look natural?” – Porcelain provides a lifelike appearance.

10. Alternatives to D6242

• D6240 (Base Metal) – Cheaper but less biocompatible

• D6245 (Full Metal) – Extremely strong but not aesthetic

• Zirconia Pontics – Metal-free, high-strength alternative

11. Maintenance and Longevity

• Brush & floss daily

• Avoid chewing hard foods (ice, hard candy)

• Regular dental check-ups

12. Case Studies and Success Rates

Studies show 90%+ success rates at 10 years for high noble metal pontics.

13. Conclusion

The D6242 dental code represents a high-quality pontic option combining porcelain aesthetics with high noble metal strength. While more expensive than base-metal alternatives, its durability, biocompatibility, and natural appearance make it a preferred choice for long-term tooth replacement.

14. FAQs
