D6116 Dental Code: Implant-Supported Dentures

The D6116 dental code is a billing code used by dentists to classify implant-supported dentures—a revolutionary solution for patients missing multiple teeth. Unlike traditional dentures, which rely on adhesives or suction, implant-supported dentures are anchored securely to dental implants, providing superior stability, comfort, and functionality.

This article will explore everything you need to know about D6116, including its benefits, procedure, costs, and how it compares to other dental implant codes. Whether you’re a patient considering implant dentures or a dental professional looking for detailed insights, this guide provides exclusive, well-researched, and comprehensive information.

2. Understanding Dental Implant Codes

Dental procedures are categorized using Current Dental Terminology (CDT) codes, maintained by the American Dental Association (ADA). These codes help standardize billing and insurance claims.

D6116 specifically refers to a fixed (non-removable) denture supported by implants, offering a permanent solution for edentulous patients.

3. What Does D6116 Cover?

The D6116 code includes:

• Surgical placement of implants (usually 4-6 per arch)

• Abutments (connectors between implants and dentures)

• Custom-fabricated denture prosthesis (fixed in place)

Unlike D6110 (removable implant dentures), D6116 provides a permanent solution that doesn’t require removal for cleaning.

4. Types of Implant-Supported Dentures

There are two main types:

1. Bar-Retained Dentures – A metal bar connects implants, and the denture snaps onto it.

2. Ball-Retained Dentures – Each implant has a ball attachment that fits into sockets on the denture.

Both types offer superior stability compared to traditional dentures.

5. Benefits of Implant-Supported Dentures (D6116)

✅ Improved Chewing Efficiency – Functions like natural teeth.
✅ No Slipping or Discomfort – Eliminates denture adhesives.
✅ Bone Preservation – Prevents jawbone deterioration.
✅ Long-Term Durability – Lasts 15+ years with proper care.

6. Who Is a Candidate for D6116?

Ideal candidates:
✔ Patients missing all teeth in an arch.
✔ Those with sufficient jawbone density (or willing to undergo bone grafting).
✔ Non-smokers (smoking affects healing).

A dental CT scan helps determine eligibility.

7. The Procedure: Step-by-Step Process

1. Consultation & Planning – 3D imaging and treatment plan.

2. Implant Placement – Surgery to insert titanium posts.

3. Healing (Osseointegration) – 3-6 months for bone fusion.

4. Abutment Attachment – Connectors placed on implants.

5. Denture Fabrication & Fitting – Custom-made prosthesis secured.

8. Cost and Insurance Coverage

• Average Cost: $15,000 – $30,000 per arch.

• Insurance Coverage: Some plans cover partial costs (check Medicare Advantage or PPO plans).

9. Comparing D6116 with Other Implant Codes

10. Common Questions About D6116

• Can D6116 dentures be removed? No, they are fixed.

• How long do they last? 15-20 years with care.

• Does Medicare cover D6116? Typically no, but some supplemental plans do.

11. Potential Risks and Complications

• Infection (rare, if oral hygiene is maintained).

• Implant Failure (if bone doesn’t fuse properly).

• Prosthesis Wear (may need replacement after 10+ years).

12. Maintenance and Longevity

• Brush & floss daily.

• Regular dental check-ups.

• Avoid hard foods that could damage the denture.

13. FAQs About D6116

Q: How many implants are needed for D6116?
A: Typically 4-6 implants per arch.

Q: Are implant dentures better than traditional dentures?
A: Yes—more stable, comfortable, and natural-feeling.

Q: Can I get D6116 on the NHS (UK)?
A: Rarely—most patients opt for private treatment.

14. Conclusion

The D6116 dental code represents a fixed, implant-supported denture, offering unparalleled stability and function compared to traditional dentures. While costly, its long-term benefits make it a worthwhile investment for eligible patients. Always consult a prosthodontist to determine if D6116 is right for you.
