or hollow. The surface may be coated, smooth, or
* subperiosteal implant: a dental implant placed
on the external surface of the maxillary or mandibular alveolar or basal bone. It is designed to
provide support for attachment of a dental prosthesis. The implant is not designed to enter the
bone, although there may be retentive screws
that do or, with time, the implant may settle into
the supporting bone.
implant abutment n: a part or section of an implant
or that which is connected to the implant that allows
for the connection to a crown, prosthesis, or other
implant connecting bar n: slang for a device made of
metal or other materials that attaches to 1 or more
implant abutments and serves to act as a framework.
implant crown n: slang for a crown that is attached to
the abutment of an implant as opposed to being attached to a natural tooth.
implant dentistry n: the field of dentistry relating to
implants and involving all aspects of implantology
from the initial planning phase to the care and maintenance oriented toward enhancing the likelihood of
a long-term successful outcome.
implant fixture n: another name for an implant.
implant infrastructure n: when applied to endosseous cylindrical implants this slang term refers to the
implant interface n: the portion of the implant that
provides a surface upon which the surrounding host
implantology n: traditionally, the study or science of
placing and restoring dental implants.
implant prosthesis n: a prosthetic device attached to
1 or more implants.
implant prosthodontics n: the area of prosthodontics that deals with the replacement of maxillofacial
structures (including teeth) by prostheses that attach
to dental implants.
implant substructure n: (1) the metal framework of a
subperiosteal implant that is beneath the soft tissue;
(2) metal framework (skeleton) placed beneath soft
tissues in contact with bone and stabilized by screws
into bone; supports prosthesis, usually with superstructure apparatuses.
implant surgery n: the surgical placement of an implant.
impression n: a replica in a negative form of areas of
the oral cavity; often used for dental treatment planning and/or dental prosthesis construction.
impression coping n: a device used in an impression
to relate an implant position to the adjacent and
opposing dentition for the purpose of fabricating a
prosthetic crown. Multiple impression copings can
be used to relate multiple implants.
incisal guidance n: the motion of the mandibular anterior teeth incisal edges against the lingual surfaces
of the maxillary anterior teeth during a protrusive
movement that usually causes a separation of the
posterior teeth. A lack of this guided movement of
the anterior teeth may allow free motion of the jaws,
which may cause undue wear or promote parafunction or bruxism.
incisal guide angle n: the angle formed by the plane
of the occlusal table and the line that connects the
incisal edges of the maxillary and mandibular incisors.
incision n: a cut or surgical wound created by a sterile
scalpel, electrosurge tip, laser tip, or similar device
incision and drainage n: the surgical procedure of cutting into a lesion to allow the release of an exudate.
incisive foramen n: an anatomic hole, usually found
lingual to the maxillary central incisors, that allows
passage of the vascular and neural tissues that supply the anterior maxilla.
incisive papilla n: see under papilla.
induction n: the act of inducing or causing to occur as
referenced in the induction of bone formation.
indurate v: toughen or harden; make hard.
infectious adj: capable of causing infection; caused by
or capable of being transmitted by infection; infective.
inflammation n: a localized protective reaction of tissue to irritation, injury, or infection elicited by proximate microbes and/or tissue injury and associated
