Coverage Summary

Scope: This policy defines indications, contraindications, and related guidance for fixed partial dentures (fixed bridges), resin-bonded appliances, provisional fixed partial dentures, repairs, precision attachments, connector bars, and stress breakers, and lists applicable CDT procedure codes. Coverage is subject to the member-specific benefit plan and any applicable federal/state mandates; the member-specific benefit plan governs in case of conflict.

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Medical Necessity Criteria

Indications for Fixed Partial Dentures

Fixed partial dentures may be indicated when ALL of the following are met:

ALL of the following

Replacement of missing permanent teeth in which the Retainer/Abutment teeth have a favorable long-term prognosis
Replacement of one to two missing teeth in a Tooth Bounded Space

Indications for Resin Bonded Appliances (e.g., Maryland Bridge)

Resin bonded appliances are indicated when ALL of the following are met:

ALL of the following

Replacement of one missing tooth
Retainer/Abutment teeth are unrestored/undamaged

Contraindications / Not Indicated

Fixed partial dentures are not indicated when ANY of the following are present:

ANY of the following

Members with rampant caries and/or poor oral hygiene
Retainer/Abutment teeth have untreated endodontic pathology or periodontal disease or an unfavorable crown root ratio
Teeth intended as Retainers/Abutments have inadequate remaining tooth structure
A tooth to be used as a Retainer/Abutment has tipped or drifted into edentulous space

Cantilever and Resin Bonded Bridges Not Indicated For

Indications for Provisional Fixed Partial Dentures

Provisional fixed partial dentures may be indicated when ANY of the following apply:

ANY of the following

A permanent fixed partial denture does not have a favorable long-term prognosis
To replace a lost tooth in members with a Mixed Dentition to allow maturity of the dentition and jaws before constructing a definitive fixed prosthetic appliance
When a systemic medical condition prohibits the placement of a definitive fixed prosthetic appliance

Fixed Partial Denture Repair (Necessitated by Restorative Material Failure)

Repair may be indicated when ALL of the following are met:

ALL of the following

The appliance to be repaired is functional
The appliance has a favorable long-term prognosis

Indications for Precision Attachments

Precision attachments may be indicated when ANY of the following apply:

ANY of the following

When aesthetics need to be considered
For the redistribution of occlusal forces
To minimize trauma to soft tissue
Control of loading and rotational forces
When it is not possible to prepare two Retainers/Abutments with a common path of placement

Indications for Connector Bar

Connector Bars may be indicated when ALL of the following apply:

ALL of the following

To brace individual Retainer/Abutment teeth with considerable coronal length for enhanced stabilization of removable partial dentures, complete dentures, and overdentures

Indications for Stress Breaker (Non-Rigid Connector)

Stress Breakers may be indicated when ANY of the following apply:

ANY of the following

When it is not possible to prepare two Retainers/Abutments with a common path of placement
When the prognosis of a Retainer/Abutment is uncertain
Control of loading and rotational forces
Redistribution of occlusal forces

Provider Actions & Documentation Requirements

Documentation Required

Member-specific benefit and mandate check

Verify the member specific benefit plan document and applicable federal/state mandates before relying on this policy; in event of conflict, the member specific benefit plan governs.

Documentation Required

Clinical indication documentation

Document favorable long-term prognosis of Retainer/Abutment teeth, presence of a Tooth Bounded Space for 1–2 missing teeth, and absence of contraindications such as rampant caries, untreated endodontic or periodontal disease, inadequate remaining tooth structure, or a tooth that has tipped or drifted into the edentulous space.

Favorable long-term prognosis of Retainer/Abutment teeth
Presence of a Tooth Bounded Space for replacement of one to two missing teeth
No rampant caries or poor oral hygiene
No untreated endodontic pathology or periodontal disease and acceptable crown-root ratio
Adequate remaining tooth structure for intended Retainers/Abutments
Retainers/Abutments are not tipped or drifted into the edentulous space

Background and Definitions

Biomechanical concerns exist when connecting natural teeth to dental implants because natural teeth (with a periodontal ligament) exhibit slight physiological movement while implants are osseointegrated and immobile; this differential movement can create stress at the implant neck and risk fracture, loss of osseointegration, or loosening of implant components. The guideline notes controversy around such connections and cites literature (e.g., Yilmaz) describing these risks. Treatment decisions about combining tooth and implant support should be individualized based on the patient’s clinical needs, prognosis of abutment teeth, occlusal and parafunctional considerations, and professional guidance (e.g., Al-Omiri). Professional parameters of care and specialty guidance (ACP, AAPD, ADA) and peer-reviewed studies inform these individualized decisions.

Term	Definition
Abutment	A tooth, portion of a tooth, or dental implant portion that serves to support and/or retain a prosthesis.
Cantilever Fixed Dental Prosthesis	A fixed complete or partial denture in which the Pontic is retained and supported only on one end by one or more Abutments.
Connector Bar	Device attached to fixed partial denture Retainer or coping to stabilize and anchor a removable overdenture prosthesis.
Fixed Dental Prosthesis	Any prosthesis securely fixed to natural teeth or implants that cannot be removed by the patient.
Mixed Dentition	Approximately age 6 to 13 when primary and permanent teeth are present.
Pontic	An artificial tooth on a fixed dental prosthesis that replaces a missing natural tooth.
Precision Attachment	An interlocking device with one component fixed to an Abutment and the other integrated into a removable dental prosthesis.
Resin-Bonded Prosthesis	A fixed prosthesis luted to tooth structures, primarily enamel, etched to provide mechanical retention for resin cement.
Retainers	Any device used for the stabilization or retention of prosthesis.
Stress Breaker	Part of a prosthesis designed to relieve Abutment teeth and supporting tissues from harmful stresses.
Tooth Bounded Space	A space created by one or more missing teeth that has a tooth on each side.
