Subject: Bone Replacement Grafts for Periodontal Surgical Procedures
Date: November 5, 2013
This Clinical Policy Bulletin explains how we determine whether certain services or supplies are medically necessary. We made these decisions based on a review of currently available clinical information including:
We expressly reserve the right to revise these conclusions as clinical information changes, and welcome further relevant information.
Each benefits plan defines which services are covered, which are excluded and which are subject to dollar caps or other limits. Members and their dentists will need to consult the member's benefits plan to determine if any exclusions or other benefits limitations apply to this service or supply. The conclusion that a particular service or supply is medically necessary does not guarantee that this service or supply is covered (that is, will be paid for by Aetna) for a particular member. The member's benefits plan determines coverage. Some plans exclude coverage for services or supplies that we consider medically necessary. If there is a discrepancy between this policy and a member's plan of benefits, the benefits plan will govern. In addition, coverage may be mandated by applicable legal requirements of a state, the federal government or CMS for Medicare and Medicaid members.
We consider this surgical procedure to be dental-in-nature (DIN) oral surgery. Coverage may be available for DIN oral surgery procedures under either medical or dental plans.
Bone replacement grafts for minor dentoalveolar bone defects may be necessary for various reasons. Bone defects are most often present in conjunction with pathology that is associated with the teeth (for example, periodontal disease or periapical disease) or can be the result of minor oral trauma such as occurs with the extraction of teeth, root amputation or hemisection of a tooth. The bone grafts are used in an attempt to restore normal architecture to the bone that supports the teeth, increasing stability of the affected tooth/teeth.
Periodontal loss of bone can occur in either a vertical or horizontal manner on either the mesial or distal aspects of the roots. With advanced cases of localized or generalized periodontitis, loss of bone may be demonstrated within the furcation of the molar teeth. The furcation is defined as the anatomic area of a multi-rooted tooth where the roots diverge.
Review of recent literature related to bone grafting of bone defects describes the success or failure of bone replacement grafts within various furcation defects. Class 2 furcation defects located on the buccal of maxillary and mandibular molars and on the lingual of mandibular molars often respond favorably to bone replacement procedures. However, palatal Class 2 furcation defects on maxillary molars and any Class 2 furcation defect on maxillary first bicuspid teeth usually respond less favorably to bone grafting procedures. Class 3 furcation involvement (through and through from buccal to lingual and mesial to distal) do not respond well to bone replacement grafts and have fair to poor long-term prognosis.1
Necessity for osseous grafts is based on radiographic evidence of vertical (intrabony) osseous defects and/or the millimeter pattern of periodontal pocket measurements provided on a six-point-per-tooth chart. For example, in areas where there is radiographic evidence of horizontal bone loss and minimal pocket depth determinations, a graft placement would not be considered appropriate.
