D6252 Dental Code: Pontics, Types, and Clinical Applications
The D6252 dental code is a specific procedural code used in dental billing to describe the placement of a pontic in a fixed partial denture (FPD), also known as a dental bridge. Unlike removable prosthetics, a pontic is a false tooth anchored to adjacent abutment teeth or dental implants, providing a permanent solution for missing teeth.
This code is crucial for dental professionals and insurance providers, as it ensures accurate billing and treatment documentation. Understanding D6252 helps dentists, hygienists, and billing specialists streamline patient care while maximizing insurance reimbursements.
Why is D6252 Important?
-
Ensures standardized billing in prosthodontics.
-
Helps in treatment planning for missing teeth.
-
Facilitates insurance claims and reduces disputes.
2. Understanding Pontics in Prosthodontics
A pontic is an artificial tooth that replaces a missing natural tooth in a fixed dental bridge. It is attached to crowns (abutments) on adjacent teeth or implants. The design and material of a pontic influence aesthetics, functionality, and oral hygiene.
Key Characteristics of an Ideal Pontic:
✔ Biocompatibility – Should not irritate soft tissues.
✔ Aesthetics – Must blend naturally with adjacent teeth.
✔ Functionality – Should restore chewing efficiency.
✔ Easy Maintenance – Designed for proper cleaning.
3. Types of Pontics and Their Clinical Applications
Pontics are classified based on their shape, material, and contact with the gingiva.
Table: Types of Pontics and Their Uses
| Pontic Type | Description | Best For |
|---|---|---|
| Ridge Lap Pontic | Contacts the alveolar ridge | Posterior teeth |
| Sanitary/Hygienic Pontic | Elevated design for easy cleaning | Mandibular molars |
| Ovate Pontic | Sits in a soft tissue depression | Maxillary anterior teeth |
| Conical Pontic | Pointed design for minimal contact | Mandibular incisors |
A. Ridge Lap Pontic
-
Most common in traditional bridges.
-
Mimics natural tooth emergence.
-
Requires meticulous hygiene to prevent plaque buildup.
B. Sanitary (Hygienic) Pontic
-
Elevated from the gumline for easy cleaning.
-
Ideal for posterior teeth where aesthetics are less critical.
C. Ovate Pontic
-
Best for anterior teeth due to natural appearance.
-
Requires surgical ridge augmentation in some cases.
D. Conical Pontic
-
Minimal tissue contact.
-
Used in areas with limited space.
4. D6252 vs. Other Dental Codes: Key Differences
| Code | Description | When to Use |
|---|---|---|
| D6252 | Pontic – fixed partial denture | For bridges with artificial teeth |
| D6210 | Pontic – cast high noble metal | When using gold alloys |
| D6240 | Pontic – porcelain fused to metal | For PFM bridges |
| D6545 | Retainer – cast metal for resin bridge | For Maryland bridges |
Key Takeaway:
-
D6252 is a general code for pontics, while others specify materials.
-
Insurance coverage varies based on the code used.
5. Materials Used for Pontic Fabrication
A. Porcelain (Ceramic)
✔ Highly aesthetic
✔ Stain-resistant
✖ Brittle under excessive force
B. Zirconia
✔ Extremely durable
✔ Excellent for posterior bridges
✖ Higher cost
C. Metal (Gold Alloys)
✔ Long-lasting
✔ Ideal for posterior teeth
✖ Less aesthetic
D. Composite Resin
✔ Affordable
✔ Easily repairable
✖ Prone to staining
6. Step-by-Step Procedure for Pontic Placement

-
-
Tooth Preparation
-
Reshape abutment teeth for crowns.
-
-
Impressions & Temporary Bridge
-
Take molds for lab fabrication.
-
Place a temporary bridge.
-
-
Pontic Fabrication (Lab Process)

-
7. Common Challenges and Solutions in Pontic Cases
| Challenge | Solution |
|---|---|
| Poor Aesthetics | Use layered porcelain or zirconia |
| Gum Irritation | Adjust pontic contour |
| Plaque Accumulation | Recommend water flossers |
8. Insurance and Reimbursement for D6252
-
Most PPO plans cover 50-80% of pontic costs.
-
HMO plans may require pre-authorization.
-
Documentation (X-rays, photos) improves claim approval.
9. Case Studies and Clinical Examples
Case 1: Anterior Ovate Pontic
-
Patient: 35-year-old female missing #8 (maxillary incisor).
-
Solution: PFM ovate pontic with ridge augmentation.
-
Outcome: Excellent aesthetics and function.
Case 2: Posterior Hygienic Pontic
-
Patient: 60-year-old male missing #30 (mandibular molar).
-
Solution: Zirconia sanitary pontic.
-
Outcome: Easy maintenance and durability.
10. FAQs on D6252 Dental Code
Q1: Does D6252 cover implant-supported pontics?
A: No, implant pontics fall under D6057.
Q2: How long does a pontic last?
A: 10-15 years with proper care.
Q3: Can a pontic be repaired if damaged?
A: Yes, depending on material (composite can be patched).
11. Conclusion
The D6252 dental code is essential for billing pontics in fixed bridges. Understanding pontic types, materials, and placement ensures optimal patient outcomes. Proper documentation maximizes insurance reimbursement, while selecting the right pontic design enhances aesthetics and function.
