with pain, redness, swelling, and possible loss of
function. Its purpose is to obliterate, dilute, or wall
off the harmful agent(s) and isolate the offended
tissue(s). It is both a cellular and vascular reaction to
localized tissue damage.
infrastructure n: a metal, ceramic, or resin framework
onto which a second framework or prosthesis will be
placed or attached using chemical or physical means.
in situ adj: in position; in the place where something is
occurring or has/does occurs.
intaglio n: (1) in dentistry, the interior surface of a denture; (2) a figure carved or engraved below the surface of a hard material such as stone that would yield
an image in relief from an impression taken of the
design; (3) something carved in intaglio.
interalveolar n: the area between the alveoli.
interalveolar crest n: the most coronal portion of the
interdental bony septum.
interalveolar septum n: alveolar and trabecular bony
partition between adjacent tooth sockets.
interarch distance n: the vertical distance between
the maxillary and mandibular arches at a specified
intercondylar adj: in dentistry refers to the area between the mandibular condyles.
interim dental implant n: a temporary dental implant that allows for the use of a provisional prosthesis. These temporary implants may also be used as
stents to guide tissue healing and prevent soft tissue
collapse into a healing surgical site. These implants
have smooth machined surface to allow easier removal. Also known as provisional dental implant.
interim endosteal dental implant abutment n: a
type of dental implant abutment used only for a limited time to guide healing or shaping of the adjacent
tissues and/or attachment of a transitional prosthesis.
interim prosthesis n: a prosthesis typically used before fabrication of a definitive dental or maxillofacial prosthesis. It can be fixed or removable and is
designed to enhance esthetics, stabilize teeth, or
improve function for a limited time. Such prostheses often help guide the clinician in designing the
appearance and function of the final prosthesis. Also
known as a provisional restoration.
intermaxillary adj: between the maxillary and mandibular jaws.
intermediate abutment n: a natural tooth or dental
implant located between terminal abutments that
provides added stability and retention for the fixed
or removable prosthesis.
internal connector n: a device of varying geometric
designs used to unite parts of a fixed partial denture.
internal derangement n: abnormal positioning of the
articular disc in relation to the condyle, fossa, or articular eminence; a deviation in form or function of
the joint capsule.
interocclusal adj: the working space between the occlusal surfaces of the opposing dental arches.
interocclusal clearance n: the space between opposing arches when the mandible is in the rest position;
also known as freeway space.
interocclusal record n: a record or registration of the
positional relationship of the teeth or jaw position.
interocclusal rest space n: the measured difference in
tooth position between vertical dimension of occlusion and vertical dimension at rest.
interstitial adj: positioned between parts or spaces of
a tissue envelope.
intrabony adj: within the bone; also known as infrabony.
intramucosal adj: found within the confines of mucosa; for example, submucosal inserts attached to removable appliances to add retention.
intraosseous adj: found within bone.
intrinsic coloring n: shading or actual coloring found
within the material of a restoration.
intrusion n: apical movement of a tooth beyond the
normal boundaries of a tooth-periodontal ligament
ipsilateral adj: belonging to or occurring on the same
side of the body.
isograft n: an allogenic graft transferred between monozygotic twins. Also known as isogeneic graft, syngraft.
