2016 Glossary - 43
maxillary sinus n: bilateral anatomic space located superior to the upper jaw (maxillary) posterior alveolus.
maxillary tuberosity n: most posterior portion of the
upper jaw alveolar ridge bone.
maxillectomy n: removal of part or all of the maxillary
(upper) jaw bone structure. Also known as a maxillary resection.
maxillofacial adj: concerning or relating to the teeth,
jaws, face, head, and neck.
maxillofacial prosthesis n: a prosthesis used as a substitute for or to reposition stomatognathic or craniofacial structures. The prosthesis is usually removable
but may be fixed with the help of teeth or dental
implants. Explanatory terminology may be used to
describe the time utilization for the prosthesis, such
as surgical, interim, and definitive.
maxillofacial prosthetic adhesive n: a material used
to hold or adhere an external facial appliance or
device to the skin and its accompanying structures
adjacent to the margins of an anatomic defect for
the purpose of preventing its dislodgement during
maxillofacial prosthetics n: the subspecialty of dental
prosthodontics that is concerned with the prosthetic
replacement or reconstruction of lost stomatognathic and/or craniofacial structures.
maxillomandibular dysplasia n: disharmony between the right and left portions of the mandible
and the maxillary jaw.
maxillomandibular fixation n: a temporary fixed
connection of the maxillary and mandibular teeth,
typically with wire, for use in treating a mandible
maxillomandibular relationship n: any spatial relationship of the mandible to the maxilla.
maxillomandibular relationship record n: a registration of any position of the mandible with respect to
the maxillae. These records often capture the vertical, horizontal, and oblique planes of relationship.
maximal intercuspal contacts n: position that results
in maximal tooth contact between the mandibular
and maxillary dental arches when the jaws are in a
maximal intercuspal position n: sometimes referred
to as centric occlusion, this is the best fit of the upper
teeth to the lower teeth regardless of the position of
the mandibular condyle.
maximum bite force n: the most load a patient can
generate by intentionally biting down on an indicating device so as to measure the greatest load that
patient can generate. This measurement may influence prosthetic design, especially if the patient can
develop extreme loads.
median line n: a hypothetical line that divides the
body into left and right halves.
median mandibular point n: an obsolete term referring to a point in the median sagittal plane that is
in the center (measuring anterior to posterior) of the
median plane n: a hypothetical plane passing from anterior to posterior that divides a body into right and
mediotrusion n: movement of the nonworking condyle toward the midfacial sagittal plane.
melanoplakia n: patches of pigmentation on the oral
membrane n: thin layer of tissue that lines a cavity,
separates a space or organ, or envelops a vessel. An
example of a membrane used in surgery is the thin
material used in various periodontal or guided bone
regenerative procedures. The membrane source
may be autogenous, allogeneic, or synthetic.
meniscectomy n: surgical removal of the intra-articular disk. See discectomy.
meniscus n: as related to the temporomandibular joint,
the crescent-shaped fibrocartilaginous disk that aids
in the articulation of the joint.
metamer n: one of two objects whose colors appear
to match when viewed under certain conditions but
under alternate viewing conditions may appear different.
metameric pair n: two objects matching in apparent
color under some lighting conditions but not others.
metamerism n: pairs of objects that match in a given
hue of light but not in others.
