Helical cone beam computed tomography, Spiral cone beam computed tomography. Imaging technique that uses a cone‐shaped X‐ray beam to acquire multiple images of a patient. Images are captured on flat panel detectors or image intensifiers. Volume data can be acquired in a single rotation of the beam and the detector, at reduced radiation exposure. It…

Intended surgical cut through the neck of the condyloid process for the purpose of removing the condyle. Also used in reference to the intended surgical excision of a portion of the articulating surface of the mandibular condyle (known as a condylar shave).  

Surgery to remove the mandibular condyle.  

A rounded articular prominence found on the end of a bone, that is, relating to the mandible. It is a bilateral ellipsoidal projection found on the superior portion of the mandible’s ramus, and it articulates with the glenoid fossa. The condyle sits atop the condylar neck. The combination of the condyle and the condylar neck…

A self‐reducing incomplete or partial disarticulation of the condyle from its glenoid fossa.  

The segment of an articulator that is located in the superior posterior region of the nonmobile member that is designed to control the movement of the movable member. The pathway that the condyles traverse during translatory movements; the inclination of the path can be measured in degrees relative to the Frankfort plane.  

When the condyle is not in its natural position.  

A dislocation of the mandibular condyle, typically forward of the articular eminence; it is not self‐correcting or self‐reducing. In the jaw, a displacement of the mandibular condyle in front of the condylar eminence. It is often caused by keeping the mouth wide open for an extended time, as in dental treatment that involves a rubber…

A theoretical line traversing through the center of the mandibular condyles and around which the mandible rotates. A projected line connecting the condyles of the mandible. Movement of the mandible is rotation around this imaginary line.  

A device that replicates the position and movement of the jaws whereby the artificial condyle is represented by a metallic ball that interacts with a plane to represent the articulating surface of the temporomandibular joint. These articulators can be arcon instruments, where the metallic condyle is positioned in a similar manner to a naturally occurring…
