Number: 029 Subject: Occlusal Adjustment Date: October 13, 2008 Important Note This Clinical Policy Bulletin expresses Aetna's determination of whether certain services or supplies are medically necessary. We have reached these conclusions based on a review of currently available clinical information (including clinical outcome studies in the peer-reviewed published medical and dental literature, regulatory status of the technology, evidence-based guidelines of public health and health research agencies, evidence-based guidelines and positions of leading national health professional organizations, views of physicians and dentists practicing in relevant clinical areas, and other relevant factors). 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 eligible, 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 there are any exclusions or other benefits limitations applicable to this service or supply. The conclusion that a particular service or supply is medically necessary does not constitute a representation or warranty 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 Aetna considers 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. Policy Aetna considers occlusal adjustment to be part of and inclusive to restorative, prosthodontic and endodontic services. Occlusal adjustment is appropriate during any phase of periodontal therapy, except in the case of acute conditions. Occlusal adjustment (limited and/or complete) is considered to be therapeutic for the treatment of etiologic factors of occlusal trauma to enable patients to maintain a comfortable and functional dentition when supported by diagnostics and other documentation. Aetna does not consider occlusal adjustment the sole treatment modality for the management or prevention of temporomandibular disorders (TMD).Background Occlusal adjustment (odontoplasty) is the reshaping of occlusal surfaces of teeth to create a harmonious contact relationship between maxillary and mandibular teeth. A primary objective of occlusal adjustment is improvement of the functional relations of the dentition in such a way that the teeth and the periodontium will receive uniform stimulation and the occlusal surfaces of the teeth will be exposed to an even physiologic wear.1The rationale for doing an occlusal adjustment can be grouped into the following categories:
Occlusal adjustments are necessary when essential to reduce or eliminate traumatic occlusion or when teeth are compromised due to loss of periodontal support. Occlusal adjustments may be integral to a comprehensive restorative treatment or part of treatment to correct skeletal and occlusal disharmonies. A complete occlusal adjustment may require multiple visits, is considered part of comprehensive orthodontic treatment and is integral to orthognathic surgery. Occlusal adjustments are of limited value as the sole treatment modality for the management or prevention of TMD. Scientific evidence does not support the performance of occlusal adjustment as a general method for treating a non-acute TMD, bruxism or headaches. Literature suggests that temporary reversible measures be attempted prior to permanent irreversible disengagement procedures. Any mounting of diagnostic casts, analysis or diagnosis is considered integral to the complete adjustment.
