Medical Necessity Criteria

Alveoloplasty - Indications

Alveoloplasty is indicated for the following:

ANY of the following

Bone recontouring and smoothing as part of the tooth extraction process
Bone recontouring and smoothing as a standalone procedure prior to fixed or removable prosthetic construction
To provide stability for implant placement
Debulking procedures for pathologic conditions of the bone

Alveoloplasty - May Not Be Indicated (Contraindications / Considerations)

Alveoloplasty may not be indicated for the following:

ANY of the following

When removing bone would harm vital structures
When there is diminished volume or atypical architecture of bone
Individuals who have undergone radiation therapy to the head and neck
Individuals with an unmanaged medical condition (including but not limited to metabolic, cardiovascular, and autoimmune/inflammatory conditions, and genetic conditions that affect collagen synthesis)
Individuals taking medications that negatively affect the healing response (including but not limited to immunosuppressive agents, corticosteroids, anticoagulants, NSAIDs, and nicotine)

Vestibuloplasty - Indications

Vestibuloplasty is indicated for the following:

ANY of the following

Ridge extension, or lowering or altering submucous displacing attachments prior to prosthetic construction
To complement and complete osseous procedure when reconstructing edentulous bone
To correct inadequate or inappropriate soft tissue drape where a resection has been previously performed and prosthetic restoration requires improvement
For overall stability of a dental implant and the maintenance of bone health around an implant

Vestibuloplasty - May Not Be Indicated (Contraindications / Considerations)

Vestibuloplasty may not be indicated for the following:

ANY of the following

Individuals with an unmanaged medical condition (including but not limited to metabolic, cardiovascular, and autoimmune/inflammatory conditions, and genetic conditions that affect collagen synthesis)
Individuals taking medications that negatively affect the healing response (including but not limited to immunosuppressive agents, corticosteroids, anticoagulants, NSAIDs, and nicotine)
When there is minimal alveolar ridge height
Individuals who have undergone radiation therapy to the head and neck

When deciding coverage, reference the member specific benefit plan document as it governs if conflicts exist; check for applicable federal or state mandates.

Documentation Required

Assess contraindications and healing risk factors

Document medical history including prior head and neck radiation, unmanaged medical conditions, and medications that impair healing (immunosuppressives, corticosteroids, anticoagulants, NSAIDs, nicotine) as these may render procedures not indicated.

Prior head and neck radiation
Unmanaged medical conditions (eg, metabolic, cardiovascular, autoimmune/inflammatory, genetic conditions affecting collagen synthesis)
Medications affecting healing (eg, immunosuppressive agents, corticosteroids, anticoagulants, NSAIDs, nicotine)

Background

Alveoloplasty is a surgical procedure to recontour and/or smooth the alveolar bone, commonly performed as part of extractions or as a standalone procedure to prepare the mouth for removable or fixed prostheses and implants. Vestibuloplasty is a set of surgical procedures to increase relative alveolar ridge height, often used to lower muscle attachments and prepare the mouth for dentures or implants. The policy provides indications and lists situations where these procedures may not be indicated.

Definitions: Alveoloplasty — Surgical procedure for recontouring supporting bone, sometimes in preparation for a prosthesis. (ADA). Vestibuloplasty — Any of a series of surgical procedures designed to increase relative alveolar ridge height. (ADA).
