joints and an arbitrary point on the face) that have
been locked into place in relation to each other.
facebow transfer v: the process of conveying the recorded facebow 3-deminsional correlation of the
maxillary dental arch and additional anatomic orientation point(s) to the articulator.
face form n: the outline shape of the face from the
frontal view, designated by shape as square, tapering, ovoid, or a blend of these shapes. Facial shape
may be used to choose tooth shapes for a dental restoration to be in harmony with the facial form, creating a more natural and pleasing esthetic effect.
facet n: a small, flat visible surface on any hard body
created by function. Specifically, a facet on a tooth
may indicate wear, usually on the occlusal or incisal
surface of a tooth, which has been caused by wearing against an opposing tooth. The observation of
facets of wear on teeth can be clues to parafunctional habits or disharmony of the occlusion of opposing
teeth due to malocclusion.
facial augmentation implant prosthesis n: a maxillofacial prosthetic device created out of a material that
is biocompatible and may be generally implanted by
being laid over a bony area beneath the skin in order
to recontour portions of the facial skin to create the
desired contours. It may be premade, the prosthetic device for facial augmentation is more frequently
custom-made because of the unique nature of most
facial defects. Also called a facial implant.
facial form n: anterior view of the facial outline.
facial prosthesis n: a maxillofacial prosthetic device
that restores a portion of the face that is congenitally absent or altered due to surgery or trauma. Also
called an extraoral prosthesis or prosthetic dressing.
facial prosthetic adhesive n: a substance used to retain a facial prosthesis in its proper position.
facing n: a veneer of a restoration on a natural tooth or
prosthetic device to alter, duplicate, or improve upon
the appearance of a natural tooth.
familial adj: a condition that occurs in members of a
fatigue n: disintegration of a material related to cyclical, repeated, or applied loads that do not exceed the
yield limit. Disintegration sometimes begins as minute cracks and can be followed by a more complete
fracture, tear, or rupture. Also known as brittle failure
fenestrate v: to puncture or perforate with one or several openings.
fenestration n: a hole or opening in a body part, for example, a hole in alveolar bone or the soft tissue that
covers the root of a tooth.
ferrule n: the most apical area of preparation around
the base of a tooth beyond any core material or post
to provide retention and resistance form for a crown.
The ferrule is to be on sound tooth structure and ideally 2 mm or more in height.
festoon n: shaping of denture base material to reproduce the natural contours of gingival tissue.
festoon, gingival adj: the rounding and enlargement
of the marginal gingiva over the roots of the teeth.
fetororis n: foul or unpleasant breath odor. See also
fiber n: a filament or strandlike structure.
* collagen fiber: elastic, soft, white fibers containing protein collagen fibril bundles that are the
most representative component of all connective
* muscle fiber: skeletal or heart muscle cells.
* nerve fiber: the slim axonal process of a nerve
* periodontal fiber: typically a collection of collagenous or elastic connective tissue.
* reticular fiber: immature connective tissue fibers.
fibroblast n: the principal connective tissue cell; a flattened, irregularly branched cell with a large, oval nucleus that functions in the production and remodeling of extracellular matrix.
fibroblast growth factor n: a lineage of growth factors that are mitogenic for fibroblasts and mesoderm-derived cells.
fibroma n: fibrous connective tissue that is a benign
