intermaxillary fixation
Temporary stabilization technique that maintains occlusal relationships by connecting the upper and lower jaws.
Full Definition
Intermaxillary fixation (IMF) is a fundamental technique in oral and maxillofacial surgery used to maintain proper occlusal relationships during healing of jaw fractures or following orthognathic surgery. Methods include traditional arch bars with wire ligatures, bone-supported IMF screws, or hybrid techniques. The duration of fixation varies from immediate post-operative periods to several weeks, depending on the indication and healing requirements of the specific procedure or injury pattern.
Usage
Usage note: IMF is acceptable abbreviation after first use; distinguish from 'interdental wiring' which is more specific.
