4. in microscopy, the treatment of material so that its structure can be examined in greater detail with minimal alteration of the normal state, and also to provide information concerning the chemical properties (as of cell constituents) by interpretation of fixation reactions.
5. in chemistry, the process whereby a substance is removed from the gaseous or solution phase and localized, as in carbon dioxide or nitrogen fixation.
6. in ophthalmology, direction of the gaze so that the visual image of the object falls on the fovea centralis.

intermaxillary fixation (IMF) a technique used to stabilize a fractured jaw; the teeth are wired or banded together. Extreme caution must be exercised to insure that oral secretions and vomitus are not aspirated as the patient is unable to expectorate any fluids. Antiemetics are often administered to prevent vomiting. Wire cutters should be kept with the patient at all times.

This trismus may be probably due to the prolonged immobi-lization of the mandible in intermaxillary fixation resulting in weakening of the muscles of mastication.
