Stillman's cleft n: a localized V-shaped, apostrophe-shaped, or a slitlike indentation or recession at
the midline of the gingival margin of a tooth. It may
extend several millimeters toward the mucogingival
junction or even to or through the junction.
stipple v: the process of producing a stippled appearance of the attached gingiva or its artificial replacement.

stock tray n: a metal or plastic prefabricated impression tray used principally for preliminary impressions;
available in several standardized sizes and shapes.
stoma (pl, stomata or stomas) n: any surgically constructed opening made for drainage or other purposes.
stomatitis n: inflammation of the mucosal tissues of
the oral cavity.
stress-bearing region n: area of the maxillary or mandibular jaws that are capable of supporting a denture
prosthesis. This represents the residual ridge, buccal
shelf area, and retromolar pad for the mandibular
arch and the residual ridge and the palate for the
stress concentration n: a location in a subject or a
system where there is a remarkably higher stress
compared with other areas or points in response to
a particular load.
stress director n: any device, appliance, or system that
redirects the occlusal forces of the stomatognathic.
stroma n: the connective tissue that forms the framework of an organ, gland, or structure.
stylus tracing n: a planar tracing showing the marginal
movement of the mandible as it is scribed on a plate
attached to an arch by means of a stylus device attached to the opposing arch. The produced shape
depends on the location of the marking point relative to the tracing table during marginal mandibular
subantral augmentation n: modification of a maxillary sinus involving the lifting (elevation) of the sinus
membrane and placement of a hard tissue graft in
order to provide or build a host site for dental implants. Also known as sinus lift, sinus graft.
subacute adj: a disease falling before or between the

connector placed apical to and not in alignment with
the occlusal plane.
subocclusal surface n: an obsolete term for a segment
of a tooth's occlusal surface that is beneath the level
of the occluding portion of the tooth.
subperiosteal dental implant n: a type of dental implant placed beneath the periosteum that rests on
the surface of the bone with abutments that protrude through the oral mucosa and are used to support a dental prosthesis. See also implant, oral.
subperiosteal dental implant abutment n: an obsolete term for the component of a subperiosteal implant that protrudes through the oral mucosa and
is used for retention of a dental prosthesis. See also
