complete denture prosthodontics n: the art and science related to knowledge and skills about restoring
an edentulous arch with a dental prosthetic device.
complete facial moulage n: a process consisting of an
impression that records the soft tissue contours of
the entire face.
complicated fracture n: a break or disruption in an osseous structure that then causes an injury to adjacent
structures like an organ, nerves, or blood vessels.
compomer n: a polyacid-modified composite resin
containing an acid-modified dimethacrylate resin,
glass ionomer fillers, and a photoinitiator. The combination of components offers advantages over either of the separate components.
components of occlusion n: the structures related to
how the teeth interact, which includes the temporomandibular joints, muscles that are related, the
teeth, jaws, and other supporting or related soft and
hard tissues.
compound joint n: a joint in the body that involves 3
or more bones.
computerized tomography (CT) n: a radiologic 2-dimensional representation of a 3-dimensional depiction of a patient's anatomic structures. (See also
cone beam computerized tomography.) The images formed depict anatomic osseous structures that
can be measured and examined for dental implant
placement. A computer is used to arrange the collected radiographic images into a single view. See
also cone beam computerized tomography.
concrescence n: when the roots of adjacent teeth are
joined via cementum deposits.
concretion n: a predominantly inorganic mass in a cavity or in the tissue of an organism.
condensation n: (1) the process of using force to ensure continuity of the matrix phase and removal of
excess mercury when compacting dental amalgam;
(2) the process used to increase the density of dental
porcelains by eliminating excess water through vibration and blotting.
condylar agenesis n: a congenital anomaly depicted
by the absence of the condyle.

condylar articulator n: 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 condyle and moves against the artificial articulating surface, or non-arcon instruments,
where the metallic plane moves against the metallic
ball, unlike that which occurs in a human temporomandibular joint.
condylar axis n: a theoretical line traversing through
the center of the mandibular condyles and around
which the mandible rotates.
condylar dislocation n: a dislocation of the mandibular condyle, typically forward of the articular eminence; it is not self-correcting or self-reducing.
condylar displacement n: when the location of the
condyle is not in its natural position.
condylar guidance n: (1) 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; (2) the pathway
that the condyles traverse through during translatory movements; the inclination of the path can be
measured in degrees relative to the Frankfort plane;
(3) v: during mandibular excursive movements it is
the mandibular guidance created by the condyle
and articular disc as they move and relate to the contour of the glenoid fossae.
condylar subluxation n: a self-reducing incomplete or
partial disarticulation of the condyle from its glenoid
fossa.
condyle n: 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 is referred to as the condyloid
process or condylar process.
