* ossifying fibroma: a fibroma, normally of the
gingiva, presenting with areas of calcification or
fibro-osseous (fibro-osteal) integrated implant n:
see under implant, oral.
fibrosis n: a subsurface collagenous soft tissue replacement that occurs as a result of chronic inflammation.
The tissue appears and feels thick and dense. Fibrosis
may occur as a result of chronic inflammation around
dental implants that support prosthetic crowns. The
tissue becomes thick and enlarges with collagen
deposition in the surrounding gingival tissue. There
is usually no bleeding on probing of the surrounding sulcus. The collagenous deposition may occur
interproximally at supporting implants that fill the
embrasure space to mimic interdental papillae.
fibrous adhesion n: a fibrous band or structure by
which parts not normally connected adhere to each
fibrous ankylosis n: decreased movement of a joint
due to proliferation of fibrous tissue.
fibrous integration n: the existence of a sheet of interfering fibrous connective tissue membrane found
between a dental implant body and the contiguous
filiform papilla n: see under papilla.
final impression n: the definitive impression that embodies the completion of the registration of the surface for construction of the prosthetic replacement.
finish n: to put a definitive covering or surface on; the
enhancement of a form before polishing.
finish junction n: the marginal adaptation of tooth
finish line n: (1) a delineation line determined by 2
points; (2) the marginal extension of a tooth preparation; (3) the prearranged seam of dissimilar materials;
(4) the end portion of the prepared tooth.
firing n: the method of porcelain fusion, in dentistry,
purposely to fabricate porcelain restorations.
first-stage dental implant surgery n: the first surgical procedure in dental implant placement. For
eposteal (subperiosteal) dental implants, the initial
surgical procedure consists of full reflection of the
oral mucosa, followed by a bone impression, plus an
interocclusal record that will be used in fabricating
the implant body. Suturing the soft tissue together
completes the first stage. (2) For an endosteal implant, the first-stage surgery refers to the reflection
of the oral mucosa, preparation of the osteotomy
(implantation site), and placement of the dental implant body. Suturing the soft tissue together completes the first stage.
fissure n: any cleft or grove, naturally present; a cleft
or profound trough on the surface of a tooth, usually due to defective fusion of neighboring lobes of
fistula n: a pathologic or atypical passage that is the
result of poor healing; an unintended or unwanted
pathway between differing internal structures or
one that connects an internal structure to the (external) surface of a body; usually named according to
the body parts it connects.
* oroantral fistula: An atypical communication
between the maxillary sinus and the oral cavity.
* orofacial fistula: An atypical communication between the cutaneous surface of the face and the
* oronasal fistula: An atypical communication between the nasal cavity and the oral cavity.
fixed adj: firmly placed; immovable and stable in one
place, does not move.
fixed dental prosthesis n: a prosthetic dental device
that is firmly attached to natural teeth and/or the
abutment of a dental implant. It provides the prime
support for the device. This prosthesis is not intended to be removed by the patient.
fixed dental prosthesis retainer n: the portion of a
fixed dental device that joins the abutment(s) to the
other parts of the device.
fixed partial denture n: see fixed dental prosthesis.
fixed prosthodontics n: subdivision of prosthodontics
that is concerned with the replacement of teeth with
dental implants and/or replacement of tooth crowns
with restorations fixed in place (nonremovable).
fixture n: an endosteal dental implant. Term coined
to define an endosteal dental implant-root form,
