D6118 Dental Code: Implant-Supported Dentures

Dental implants have revolutionized restorative dentistry, offering patients a permanent solution for missing teeth. Among the various dental codes, D6118 stands out as a critical classification for implant-supported dentures, providing stability and functionality that traditional dentures cannot match.

This comprehensive guide explores everything about the D6118 dental code, including its applications, benefits, procedural details, costs, and comparisons with alternative treatments. Whether you’re a patient considering implant-supported dentures or a dental professional seeking detailed insights, this article provides an in-depth analysis.

2. What is the D6118 Dental Code?

The D6118 code is part of the American Dental Association (ADA) Current Dental Terminology (CDT) and refers to:

“Implant/abutment supported removable denture for edentulous arch – maxillary”

This means the code applies specifically to upper jaw (maxillary) implant-supported dentures that are removable but anchored by dental implants for enhanced stability.

Key Features of D6118:

• Removable prosthesis (unlike fixed implant bridges)

• Supported by implants and abutments

• Designed for completely edentulous (toothless) patients

3. Understanding Implant-Supported Dentures

Implant-supported dentures are a hybrid between traditional dentures and fixed implant prostheses. Unlike conventional dentures that rely on adhesives or suction, these dentures attach to dental implants surgically placed in the jawbone.

How They Work:

1. Implants are placed into the jawbone (typically 2-6 implants per arch).

2. Abutments connect the implants to the denture.

3. The denture snaps or clips onto the abutments, providing a secure fit.

Comparison with Traditional Dentures

4. Types of Implant-Supported Dentures

A. Bar-Retained Dentures

• A metal bar connects multiple implants.

• The denture clips onto the bar.

B. Ball-Retained Dentures (Stud-Attachment)

• Each implant has a ball-shaped abutment.

• The denture has sockets that snap onto the balls.

C. Fixed vs. Removable

• D6118 refers to removable implant dentures.

• Fixed versions (like All-on-4) are coded differently (D6010-D6199).

5. Benefits of Implant-Supported Dentures (D6118)

✅ Enhanced Stability – No slipping or discomfort while eating/speaking.
✅ Improved Oral Health – Prevents bone loss and preserves facial structure.
✅ Long-Lasting Solution – Can last 10-20 years with proper care.
✅ Natural Feel & Function – Restores nearly full chewing power.
✅ Easy Maintenance – Removable for cleaning.

6. Who is a Candidate for D6118?

Ideal Candidates:

✔ Patients missing all upper teeth.
✔ Those with sufficient jawbone density (or willing to undergo bone grafting).
✔ Individuals dissatisfied with traditional dentures.

Contraindications:

✖ Severe bone loss without grafting.
✖ Uncontrolled diabetes or immune disorders.
✖ Heavy smokers (may impair healing).

7. The Procedure: Step-by-Step Process

Step 1: Consultation & Imaging

• Dental exam, X-rays, and 3D scans.

Step 2: Implant Placement Surgery

• Implants are inserted into the jawbone.

• Healing period (3-6 months for osseointegration).

Step 3: Abutment Attachment

• Connectors are placed on the implants.

Step 4: Denture Fabrication & Fitting

• Custom dentures are made and secured.

8. Cost and Insurance Coverage for D6118

Average Cost:

• $15,000 – $30,000 per arch (varies by location, materials, and number of implants).

Insurance Coverage:

• Partial coverage possible under medical/dental plans.

• Medicare typically does not cover implants.

9. Comparing D6118 with Other Dental Implant Codes

10. Potential Risks and Complications

⚠ Infection – Proper oral hygiene is crucial.
⚠ Implant Failure – Rare but possible due to poor osseointegration.
⚠ Nerve Damage – If implants are improperly placed.

11. Aftercare and Maintenance

 Daily Cleaning – Remove and clean dentures.
Regular Check-ups – Monitor implant health.
Avoid Hard Foods – Prevent excessive pressure.

12. Frequently Asked Questions (FAQs)

Q1: How long do implant-supported dentures last?

A: 10-20 years with proper care.

Q2: Are implant dentures removable?

A: Yes, D6118 refers to removable dentures.

Q3: Does Medicare cover D6118?

A: Usually not, but some private plans may offer partial coverage.

13. Conclusion

The D6118 dental code represents a life-changing solution for edentulous patients seeking stability and functionality. Implant-supported dentures offer superior comfort, durability, and oral health benefits compared to traditional options. While the cost can be significant, the long-term advantages make it a worthwhile investment.
