D6205 Dental Code: Understanding Pontic Cast High Noble Metal
The D6205 dental code is a specific procedural term used in dental billing and treatment planning. It refers to the fabrication and placement of a pontic cast with high noble metal as part of a fixed partial denture (FPD), commonly known as a dental bridge.
This code is crucial for dentists, dental labs, and insurance providers because it defines the exact material and type of restoration being used. Unlike other pontic codes, D6205 exclusively involves high noble metal alloys, which contain at least 60% noble metals (gold, platinum, palladium) and a minimum of 40% gold.
This article will explore the clinical significance, advantages, procedure, and financial aspects of the D6205 dental code, providing an in-depth resource for dental professionals and patients alike.
2. What Is a Pontic in Dentistry?
A pontic is an artificial tooth that replaces a missing natural tooth in a dental bridge. It is anchored to adjacent teeth (abutments) or dental implants. Pontics must be biocompatible, durable, and aesthetically pleasing, depending on their location in the mouth.
Types of Pontics
| Type | Description |
|---|---|
| Ridge Lap | Contacts the gum ridge, used in posterior teeth. |
| Modified Ridge Lap | Better aesthetics, used in visible areas. |
| Hygienic/Sanitary | Elevated from gums for easy cleaning. |
| Conical | Pointed design, rarely used today. |
The D6205 code applies to pontics made from high noble metal, typically used in non-visible areas due to their metallic appearance.
3. Understanding the D6205 Dental Code: Definition and Scope
The D6205 code is defined by the American Dental Association (ADA) as:
“Pontic – cast high noble metal”
Key Features:
-
Material: Must contain ≥60% noble metals (gold, platinum, palladium) and ≥40% gold.
-
Use Case: Primarily for posterior teeth due to metal visibility.
-
Alternative Codes:
-
D6209 (Pontic – cast noble metal, less gold content)
-
D6210 (Pontic – cast base metal, non-precious alloys)
-
This code ensures insurance clarity, helping patients understand their coverage for high-quality restorations.
4. Materials Used in D6205: High Noble Metal Alloys
High noble metals are prized for their:
✔ Corrosion resistance
✔ Biocompatibility
✔ Longevity (20+ years with proper care)
Composition Breakdown
| Metal | Percentage | Role |
|---|---|---|
| Gold (Au) | 40-80% | Malleability, tarnish resistance |
| Platinum (Pt) | 5-15% | Strength, durability |
| Palladium (Pd) | 10-30% | Hardness, cost control |
Compared to base metal alloys, high noble metals are more expensive but offer superior performance.
5. Benefits of High Noble Metal Pontics
✅ Superior Longevity – Resists wear and fracture better than non-noble metals.
✅ Biocompatibility – Rarely causes allergic reactions.
✅ Precision Fit – Casts well, reducing marginal gaps.
✅ Minimal Tooth Wear – Soother against opposing teeth than porcelain-fused alternatives.
However, their metallic color makes them less ideal for anterior teeth.
6. Comparison with Other Pontic Codes
| Code | Material | Gold Content | Cost | Best For |
|---|---|---|---|---|
| D6205 | High Noble Metal | ≥40% | $$$ | Posterior teeth |
| D6209 | Noble Metal | ≥25% noble, <40% gold | $$ | Budget-friendly option |
| D6210 | Base Metal | 0% noble | $ | Cost-sensitive cases |
7. Clinical Applications of D6205
-
Molar replacements (where aesthetics are less critical)
-
Patients with metal allergies to nickel or cobalt
-
Long-span bridges needing extra strength
8. Step-by-Step Procedure for Fabricating a D6205 Pontic
-
Tooth Preparation – Adjacent teeth are shaped for crowns.
-
Impressions – Sent to a dental lab.
-
Wax Modeling – Pontic design is created.
-
Casting – High noble metal is poured into a mold.
-
Finishing & Polishing – Ensures smooth edges.
-
Cementation – Pontic is permanently bonded.
9. Common Challenges and Solutions
Challenge: High cost.
Solution: Dental insurance may cover part of the expense.
Challenge: Metallic appearance.
Solution: Use in non-visible areas or consider porcelain-fused alternatives.
10. Cost and Insurance Considerations
-
Average Cost: $800–$1,500 per pontic.
-
Insurance Coverage: Often covered at 50-80% if medically necessary.
11. FAQs About D6205 Dental Code
Q1: Is D6205 better than porcelain-fused pontics?
A: D6205 is more durable but less aesthetic. Porcelain-fused is better for front teeth.
Q2: How long does a D6205 pontic last?
A: 15-30 years with proper care.
Q3: Does insurance cover D6205?
A: Many plans cover it, but check your policy.
12. Conclusion
The D6205 dental code represents a high-quality, long-lasting pontic made from high noble metal, ideal for posterior teeth. While costly, its durability and biocompatibility make it a preferred choice for many patients. Understanding this code helps in treatment planning, insurance claims, and patient education.
