A line diagram that is a copy of the structural landmarks of the orthodontically relevant craniofacial markers and facial bones. It is made by drawing on a thin paper sheet placed on a cephalometric radiograph through which light is projected.  

A standardized radiograph of the head used for making cranial measurements.  

Occlusal contacts of opposing teeth that maintain the occlusal vertical dimension between the maxillary and mandibular arches.  

The physical movement of the mandible as it transits from centric occlusion to maximum intercuspation.  

A registration of the relationship between the maxilla and mandible when the mandibular condyles are in centric relation. The record may be taken intraorally or extraorally.  

The maxillomandibular relationship in which the condyles articulate with the thinnest avascular portion of their respective disks with the complex in the anterior‐superior position against the shapes of the articular eminences. This position is independent of tooth contact. This position is clinically discernible when the mandible is directed superior and anteriorly. It is restricted to…

The physical distance that exists between centric relation and maximum intercuspation as viewed in the horizontal and sagittal planes.  

An occlusal contact or interference that occurs before a balanced and stable jaw‐to‐jaw relationship is reached in centric occlusion or centric relation.  

The position of the mandible in either centric occlusion or centric relation. The most posterior position of the mandible in relation to the maxilla.  

The maximum balanced intercuspation of maxillary and mandibular teeth; may or may not coincide with centric relation. Positional relationship of occluding tooth surfaces when the mandible is in centric relation. The coincidence of centric occlusion and centric relation is desirable when creating an occlusion, but the maximal intercuspal relationship may not always exist. (Acquired centric…
