2016 Glossary - 20
denture foundation area n: the surfaces of the oral
soft tissue used to support a dental prosthesis that
replaces missing natural teeth with artificial teeth.
denture occlusal surface n: the designated chewing
portion of a dental prosthesis with artificial teeth
that makes contact with the opposing dentition.
denture prognosis n: an attempt by a clinician or laboratory technician to predict the success of a denture
before starting the therapy.
denture prosthetics n: the science of replacing natural
teeth in a complete arch with an artificial substitute
that is both functional and cosmetically pleasing.
denture resin packing n: the placement of a denture
base material with pressure into a mold positioned in
the refractory flask.
denture retention n: a measure of a denture's resistance to movement away from its supporting soft tissue base. See also denture stability.
denture service n: the clinical practices provided in the
diagnosis, assembly, and maintenance of dentures.
denture space n: (1) the 3-dimensional area of the
mouth that is or may be occupied by maxillary and/
or mandibular denture(s); (2) the space once occupied by teeth, alveolar bone, and surrounding soft
and hard tissues but is now available for a complete
or partial denture.
denture stability n: (1) a measure of the resistance of
a denture to lateral (horizontal) movement on its tissue foundation; (2) a characteristic of a denture that
permits it to remain firmly seated in relation to its
soft tissue foundation and/or abutment teeth.
denture supporting structures n: the remaining alveolar ridges or teeth that serve as foundational support for a removable partial or full denture.
depassivation n: removal or loss of the protective oxide layer of a metal that creates a more reactive surface.
deprogrammer n: any device that alters reflexive proprioceptive behavior during mandibular closure.
desquamation n: the loss of surface epithelial cells
through the process of exfoliation.
determinants of mandibular movement n: the anatomic and physiologic factors that determine the
envelope of function. These include the dental structures, occlusion, temporomandibular joint apparatus, and neurosensory function.
detrusion n: distraction (downward movement) of the
developmental dysmorphia n: anomalous growth
related to or induced by interference from neighboring structures.
developmental dysplasia n: an abnormal growth pattern at the cellular or organ level.
developmental hyperplasia n: excessive growth of
tissue or organ system.
developmental hypoplasia n: less than normal
growth of tissue or organ system.
devest v: removal of investing material to retrieve a
casting or prosthesis.
deviation n: regarding movement of the mandible, a
movement or position that is other than ideal or desirable; it may be caused by interference or developmental abnormality.
device n: an apparatus developed by the application
of principles or ideas to secure a specific outcome or
devitrification n: the process by which glassy substances change their structure to crystalline solids.
This phenomenon may occur partially in dental ceramics if a ceramic restoration is fired too often, and it
is typically associated with an opacified appearance.
diagnose v: to identify or define a disease or unwanted
pathological condition by study of and deliberation
on the signs and symptoms the patient presents with.
diagnosis n: (1) the art and science of identifying and
differentiating abnormalities from health and discerning the probable causes; (2) the identification
and description of the nature, location, and basis of a
disease or condition.
diagnostic adj: relating to or used in determining the
nature of a disease or condition.
diagnostic cast n: a static replica of a part or parts of
the oral cavity and/or facial structures for the purpose of diagnosis and development of a treatment
plan. See also cast.
