Comprehensive Guide to D7710 Dental Code: Fixed Partial Denture Repair

Fixed partial dentures (FPDs), commonly known as dental bridges, are a popular tooth replacement solution for patients missing one or more teeth. However, like any dental prosthesis, they may require repairs due to wear, damage, or complications. The D7710 dental code is specifically used to bill for the repair of a fixed partial denture.

This comprehensive guide explores everything you need to know about the D7710 code—its applications, procedures, costs, and alternatives. Whether you’re a dental professional, a patient, or an insurance provider, this article provides in-depth insights into this essential dental service.

2. Understanding the D7710 Dental Code

The D7710 code is part of the American Dental Association (ADA) Current Dental Terminology (CDT) and is classified under Fixed Prosthodontics. It refers to:

“D7710 – Repair of fixed partial denture (broken or fractured) – includes reattachment of loose retainer or replacement of broken teeth.”

This means the code covers:

• Reattaching a loose retainer

• Replacing a broken artificial tooth

• Repairing fractures in the pontic or framework

Key Features of D7710:

• Non-routine procedure (not part of regular maintenance)

• Covers only repairs (not adjustments or relines)

• Excludes implant-supported bridges (different codes apply)

• Broken connectors between abutments

B. Loose or Detached Retainer

• Cement failure leading to a loose crown

• Need for re-cementation

C. Broken Artificial Tooth

• Chipped or fractured porcelain teeth

• Wear leading to functional issues

4. Types of Fixed Partial Denture Repairs

Depending on the damage, repairs may involve:

A. Direct Repairs (Chairside)

• Re-cementation of loose retainers

• Minor porcelain chip repairs

B. Laboratory Repairs

• Replacement of broken teeth

• Recasting fractured metal frameworks

5. Step-by-Step Procedure for D7710
