Is the resin retainer suitable for posterior teeth?

Typically, resin retainers are best suited for anterior teeth due to aesthetic considerations and the lower bite force in this area.

How long does a resin-bonded prosthesis last?

With proper care, a resin-bonded prosthesis can last between 5 to 10 years, though this can vary based on individual patient factors.

Can a resin retainer be repaired if it becomes loose?

Yes, if the retainer becomes loose, it can often be rebonded or repaired, depending on the extent of the issue.

Are there any specific patient care instructions post-procedure?

Patients should maintain good oral hygiene and avoid using the prosthesis to bite into hard foods to prolong its lifespan.

Resin Retainer Prosthesis - CDT Code Guide

Prosthodontics, fixed/Fixed Partial Denture Retainers Inlays/Onlays

Overview

CDT Code D6549 refers to a resin retainer used in resin-bonded fixed prostheses, commonly known as Maryland bridges. This procedure involves the use of a resin-based material to create a retainer that supports a fixed partial denture. Typically, this is used when a patient requires a non-invasive solution to replace missing teeth, particularly in the anterior region where aesthetics are crucial. The resin retainer is bonded to the adjacent teeth, providing support and stability to the prosthesis without the need for extensive tooth preparation. This code is essential for dental professionals to accurately document and bill for this specific type of prosthodontic treatment.

When to Use This Code

When replacing a single missing anterior tooth with minimal tooth preparation.
In cases where aesthetics are a primary concern and a metal-free option is preferred.
For patients who require a temporary solution before more permanent prosthetics.
When the adjacent teeth are healthy and do not require crowns.
In situations where a less invasive procedure is desired by the patient.

Documentation Requirements

Detailed patient history and diagnosis supporting the need for a resin-bonded prosthesis.
Clinical notes describing the tooth preparation and bonding process.
Photographic evidence of the pre- and post-procedure condition.
A clear description of the materials used for the resin retainer.
Patient consent forms acknowledging understanding of the procedure and alternatives.

Billing Considerations

Ensure that the procedure is documented as a resin-bonded prosthesis to avoid confusion with traditional fixed bridges. Check for frequency limitations as some insurers may restrict coverage for this type of prosthesis. Common modifiers include those indicating the location of the prosthesis (e.g., anterior). Verify with the patient's insurance for coverage specifics, as some plans may require pre-authorization.

Frequently Asked Questions

The primary advantage is its minimally invasive nature, preserving more of the natural tooth structure compared to traditional fixed bridges.
