D6210 Dental Code: Bridge Pontics – Cast High Noble Metal
Dental bridges are a common and effective solution for replacing missing teeth, restoring function, and improving aesthetics. Among the various dental codes used to classify bridge procedures, D6210 stands out as a premium option for patients seeking longlasting, highquality tooth replacement.
This code specifically refers to a bridge pontic made of cast high noble metal, a material known for its strength, biocompatibility, and corrosion resistance. But what exactly makes D6210 unique? How does it compare to other bridge materials? And what should patients expect during the procedure?
In this comprehensive guide, we will explore every aspect of the D6210 dental code, from its clinical applications to cost considerations, helping you make an informed decision about your dental health.
2. Understanding the D6210 Dental Code
Definition and Purpose
The D6210 code, as defined by the American Dental Association (ADA), refers to a pontic (false tooth) in a fixed bridge that is fabricated using a cast high noble metal alloy.
-
Pontic: The artificial tooth that replaces the missing natural tooth.
-
Fixed Bridge: A nonremovable prosthetic device cemented to adjacent teeth or implants.
-
Cast High Noble Metal: An alloy containing at least 60% noble metals (gold, platinum, palladium), with gold making up at least 40% of the composition.
This combination ensures exceptional durability, minimal corrosion, and biocompatibility, making it ideal for longterm dental restorations.
When Is D6210 Used?
Dentists recommend D6210 bridges in cases where:
-
A patient is missing one or more teeth but has healthy adjacent teeth for support.
-
The bridge is placed in an area requiring high strength and longevity (e.g., molars).
-
The patient prefers a metalbased restoration over porcelain or zirconia.
3. Types of Dental Bridges
| Type of Bridge | Description | Best For |
|---|---|---|
| Traditional Bridge | Uses crowns on adjacent teeth to hold the pontic. | Replacing one or more missing teeth with strong natural teeth nearby. |
| Cantilever Bridge | Only one adjacent tooth supports the pontic. | Cases where only one adjacent tooth is available. |
| Maryland Bridge | Uses a metal or porcelain framework bonded to the back of adjacent teeth. | Front teeth with minimal biting force. |
| ImplantSupported Bridge | Supported by dental implants rather than natural teeth. | Patients with multiple missing teeth or insufficient natural tooth support. |
4. Materials Used in Bridge Pontics
High Noble Metal Alloys (D6210)
-
Composition: ≥60% noble metals (gold, platinum, palladium), with ≥40% gold.
-
Advantages:
-
Highly durable (lasts 20+ years with proper care).
-
Resistant to corrosion and tarnishing.
-
Biocompatible (low risk of allergic reactions).
-
PorcelainFusedtoMetal (PFM) Bridges
-
Combines metal strength with porcelain aesthetics.
-
Common codes: D6240 (High Noble), D6245 (Noble).
Zirconia and AllCeramic Bridges
-
Pros: Excellent aesthetics, metal-free.
-
Cons: Less durable than metal for posterior teeth.
5. The Advantages of Cast High Noble Metal Pontics (D6210)
✅ Superior Longevity – Can last decades with proper care.
✅ Minimal Wear on Opposing Teeth – Softer than porcelain, reducing enamel wear.
✅ Biocompatibility – Rarely causes allergic reactions.
✅ Precision Fit – Cast metal allows for exact tooth contours.
6. The Procedure for Placing a D6210 Bridge
-
Consultation & Diagnosis – Xrays and impressions are taken.
-
Tooth Preparation – Adjacent teeth are reshaped for crowns.
-
Temporary Bridge Placement – Protects prepared teeth while the permanent bridge is made.
-
Fabrication in Dental Lab – Custom pontic is cast in high noble metal.
-
Final Placement – The bridge is cemented permanently.
7. Comparing D6210 with Other Bridge Codes
| Code | Material | Pros | Cons |
|---|---|---|---|
| D6210 | Cast High Noble Metal | Extremely durable, biocompatible | Less aesthetic (metal color) |
| D6240 | PorcelainFusedtoHighNoble | Natural appearance | Porcelain may chip over time |
| D6205 | Cast Noble Metal (25% noble) | More affordable than high noble | Less corrosion-resistant |
8. Cost and Insurance Coverage
-
Average Cost: $1,500 – $3,500 per pontic (varies by location).
-
Insurance Coverage: Many plans cover 50% of the cost.
-
Financing: Dental loans or payment plans may be available.
9. Maintenance and Care
-
Brush and floss daily.
-
Avoid hard/sticky foods.
-
Regular dental checkups every 6 months.
10. Potential Complications
-
Allergic reactions (rare).
-
Wear over time (may need replacement after 20+ years).
-
Gum irritation (adjustments may be needed).
11. Frequently Asked Questions (FAQs)
Q: How long does a D6210 bridge last?
A: With proper care, 15–30 years or more.
Q: Is a metal bridge noticeable?
A: Yes, but it’s often used for back teeth where aesthetics are less critical.
Q: Can I get an MRI with a metal bridge?
A: Yes, high noble metals are nonferromagnetic and safe for MRIs.
12. Conclusion
The D6210 dental code represents one of the most durable and longlasting options for fixed bridges. While it may not be the most aesthetic choice for front teeth, its strength, biocompatibility, and longevity make it an excellent choice for posterior restorations. Patients should consult their dentist to determine if a high noble metal bridge is the best solution for their needs.
