"Appliance placement" means the application of orthodontic attachments to the teeth for the purpose of correcting dentofacial abnormalities.

"Comprehensive full orthodontic treatment" means utilizing fixed orthodontic appliances for treatment of adolescent dentition leading to the improvement of a client's severe handicapping craniofacial dysfunction and/or dentofacial deformity, including anatomical and functional relationships.

"Craniofacial anomalies" means abnormalities of the head and face, either congenital or acquired, involving disruption of the dentition and supporting structures.

"Craniofacial team" means a cleft palate/maxillofacial team or an American Cleft Palate Association-certified craniofacial team. These teams are responsible for the management (review, evaluation, and approval) of patients with cleft palate craniofacial anomalies to provide integrated management, promote parent-professional partnership, and make appropriate referrals to implement and coordinate treatment plans.

"Crossbite" means an abnormal relationship of a tooth or teeth to the opposing tooth or teeth, in which normal buccolingual or labiolingual relations are reversed.

"Limited orthodontic treatment" means orthodontic treatment with a limited objective, not involving the entire dentition. It may be directed only at the existing problem, or at only one aspect of a larger problem in which a decision is made to defer or forego more comprehensive therapy.

"Malocclusion" means improper alignment of biting or chewing surfaces of upper and lower teeth or abnormal relationship of the upper and lower dental arches.

"Maxillofacial" means relating to the jaws and face.
