nasomandibular fixation

nasomandibular fixation

[nā′zōmandib′yoo͡lər]

Etymology: L, nasus + mandere, to chew, figere, to fasten

a type of maxillomandibular fixation to stabilize fractures of the jaw by using maxillomandibular splints connected to a wire through a hole drilled in the anterior nasal spine of the maxillary bone. It has been used particularly in edentulous patients. See also maxillomandibular fixation.

fixation

(fiksā´shn),
n the act or result of fixing, such as being bound or limited in position or relationship.

fixation, biphase pin,

n See appliance, fracture.

fixation, elastic band,

n the stabilization of fractured segments of the jaws by means of intermaxillary or maxillomandibular elastic bands applied to splints or appliances.

fixation, external pin,

n See appliance, fracture.

fixation, intermaxillary,

n See fixation, maxillomandibular.

fixation, intraosseous,

n the reduction and stabilization of fractured bony parts by direct fixation to one another with surgical wires, screws, pins, and/or plates.

fixation, mandibulomaxillary,

n See fixation, maxillomandibular.

fixation, maxillomandibular (mandibulomaxillary fixation),

n a retention of fractures of the maxillae or mandible in the functional relations with the opposing dental arch through the use of elastic wire ligatures and interdental wiring and/or splints.

fixation, nasomandibular,

n a mandibular immobilization, especially for edentulous jaws, using mandibulomaxillary splints, circummandibular wiring, and intraoral interosseous wiring through the nasal process of the maxillae.

fixation, of elements by the skeleton,

n the fixation of many elements for long periods in the bone matrix as a result of a special affinity of the elements for the matrix. Recent work with radioactive isotopes has firmly established the concept of the skeleton as a dynamic system. In addition to the changes in structure and distribution of the bone mineral mediated by cellular activity, every ionic grouping in the mineral is capable of replacement.

fixation, osseous,

n the immobilization of fractured bony segments.

fixation, radiographic,

n in film processing, the chemical removal of all the undeveloped salts of the film emulsion, so that only the developed (reduced) silver will remain as a permanent image.

fixation, restorative,

n the act of securing in position, usually by means of cementation, some treatment appliance such as a crown or fixed partial denture so that it cannot be removed.

fixation, Roger-Anderson pin,

n.pr an appliance used in extraoral fixation of mandibular fractures and prognathisms. See also appliance, fracture.
