condylectomy n: surgery to remove the mandibular
condylotomy n: 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).
cone beam computerized tomography n: a diagnostic radiographic modality where the radiation source
is sent as a cone that rotates about the target patient
to provide a variety of images. In computerized axial tomography used in the medical community the
radiation beam is flat as opposed to a cone emanation. The various target tissues absorb the radiation
completely or partially and pass the unabsorbed
radiation to a sensor. The sensor receives the radiation that is not absorbed, and hundreds of images
are formed, termed "image acquisition." Two-dimensional images are recorded and then reconstructed
by an attached computer to deliver 2-dimensional
images of a 3-dimensional construct. Various 2-dimensional images can be acquired by selecting the
desired plane from the 3-dimensional construct.
Thus, the dentist may interpret the images for surgical case planning and measurement of anatomic
continuous bar connector n: a metal bar arising from
terminal rests of key abutments resting on the cingulums of the mandibular anterior teeth so that it aids in
their stabilization and functions as an indirect retainer in a free end distal extension dental prostheses.
continuous beam n: a beam that spans over 3 or more
abutments and resists bending when a load or force
contracture n: a shortening of a muscle that is permanent and a consequence of fibrosis.
contralateral adj: relating to or pertaining to or occurring on the opposite side. The working of the opposite side in concert with similar parts on the primary
side of interest; the opposite of ipsilateral.
coping n: a thin layering, covering, or crown; something similar to a cope (as by concealing or covering).
coping impression n: an impression that employs resin or metal copings on prepared teeth and most often involves an entire dental arch.
copper band n: a cylinder made from copper and used
as a matrix for making an impression.
coraliform adj: possessing the form of coral; coral-like in its branching; usually with reference to
various types of implant materials made from hydroxyapatite.
coronal adj: (1) in dentistry, relating to a tooth's natural
or prosthetic crown; (2) in anatomy, the plane that
runs along the long axis of the body.
coronal plane n: aligning in the direction of the coronal suture, the plane that separates the front from
the back of the body.
coronoidectomy n: surgical excision of the coronoid
corrode v: (1) to deteriorate or oxidize a metal as a result of electrochemical reaction within its the environment; (2) gradual deterioration, usually by chemical action.
corrosion n: (1) the deterioration of a material by electrochemical reaction with the environment. The
term corrosion usually refers to oxidation of metals,
known as rusting, which results in a layer of oxide or
salt on the surface. The deterioration often affects
properties of the material, such as strength, appearance, and permeability. Corrosion can also occur in
other materials, such as ceramics or polymers; (2) the
action, process, or effect of corroding; a result of corroding; (3) the loss of elemental components to the
corrosive adj: having the power to induce corrosion.
cortical bone n: the outer layer of osseous tissue. Cortical bone is one of the 2 categories of osseous tissue
that make up bone. Cortical bone, the outer layer, is
dense, in contrast to the inner layer, called cancellous
bone, which is much less dense. Also known as compact bone.
cover screw n: also known as the healing screw; the
element of an endosteal dental implant used to seal
the internal threaded section of a dental implant
body during the healing phase. This healing screw
