D7720 Dental Code: Periodontal Splinting for Tooth Stabilization

The D7720 dental code refers to periodontal splinting, a procedure designed to stabilize mobile teeth caused by periodontal disease, trauma, or occlusal imbalances. This code is specifically used when a dentist bonds teeth together to reduce mobility and improve function.

Periodontal splinting is a crucial treatment in restorative and periodontal dentistry, helping patients regain chewing efficiency, reduce pain, and prevent further tooth loss. Unlike temporary splints (D4341/D4342), D7720 is often a semi-permanent or permanent solution, depending on the materials and technique used.

This article will explore everything you need to know about D7720, including its clinical applications, procedure steps, materials, costs, and post-operative care.

2. What Is Periodontal Splinting?

Periodontal splinting involves joining two or more teeth together to distribute biting forces evenly and reduce mobility. This is achieved using:

• Composite resin bonding

• Fiber-reinforced splints

• Wire and acrylic splints

• Orthodontic retainers (in some cases)

The goal is to improve tooth stability, enhance patient comfort, and prevent further periodontal damage.

3. Indications for D7720: When Is It Needed?

D7720 is typically recommended for patients with:
✔ Moderate to severe tooth mobility (Miller Class II or III)
✔ Periodontal disease-related loosening
✔ Trauma-induced tooth mobility
✔ Teeth weakened by bruxism or occlusal trauma
✔ Post-orthodontic stabilization

Contraindications

❌ Severe bone loss with no salvageable teeth
❌ Active periodontal infection (needs treatment first)
❌ Poor oral hygiene (increases failure risk)

4. Types of Periodontal Splinting Techniques

5. Materials Used in Periodontal Splinting

• Composite Resin (Bis-GMA based)

• Ribbond® (Polyethylene Fiber)

• EverStick® (Glass Fiber)

• Stainless Steel Wire (for rigid splints)

Each material has unique properties affecting longevity and aesthetics.

6. Step-by-Step Procedure for D7720

1. Diagnosis & Treatment Planning (X-rays, mobility assessment)

2. Teeth Preparation (Cleaning, etching if using resin)

3. Splint Application (Bonding fibers/resin or securing wire)

4. Curing & Polishing

5. Bite Adjustment (Ensuring proper occlusion)

7. Benefits of Periodontal Splinting

• Reduces tooth mobility

• Improves chewing function

• Prevents further bone loss

• Minimizes discomfort

8. Potential Risks and Complications

• Debonding (Splint failure)

• Plaque accumulation (Requires strict hygiene)

• Allergic reactions (Rare, material-dependent)

9. D7720 vs. Other Dental Splinting Codes

10. Cost and Insurance Coverage for D7720

• Average Cost: $300-$800 per arch

• Insurance Coverage: Varies (often covered under periodontal benefits)

11. Patient Care and Post-Procedure Instructions

• Avoid hard foods for 24-48 hours

• Maintain excellent oral hygiene

• Schedule follow-ups for splint evaluation

12. FAQs About D7720 Dental Code

Q1: How long does a D7720 splint last?

A: Typically 1-5+ years, depending on materials and oral hygiene.

Q2: Does periodontal splinting hurt?

A: No, it’s a non-invasive procedure done under local anesthesia if needed.

Q3: Can splinted teeth be cleaned normally?

A: Yes, but interdental brushes/floss threaders may be needed.

13. Conclusion

The D7720 dental code is essential for stabilizing mobile teeth, improving function, and preventing further periodontal damage. With various materials and techniques available, dentists can customize treatment for long-term success. Proper patient care and maintenance are crucial for durability.
