What is MMF mandible fracture?
Mandibulo-maxillary fixation (MMF) screws are inserted into the bony base of both jaws in the process of fracture realignment and immobilisation. The screw heads act as anchor points to fasten wire loops or rubber bands connecting the mandible to the maxilla.
What is MMF procedure?
Maxillomandibular Fixation (MMF) is a fundamental component in the management of facial trauma, reconstruction and orthognathic surgery. This is done to ensure the interrelationship of the dental occlusion, which is necessary in the reduction of traumatic or surgically induced segments of the mandible and maxilla.
What is MMF in dentistry?
Maxillomandibular fixation (MMF) is important in the treatment of maxillofacial fractures and is usually applied by wiring together the fixed upper and lower arch bars. Here, we report a new type of MMF technique, Rohtak Dental College (RDC) technique using 26-gauze stainless steel wires.
What is MMF IMF?
IMF screws are inserted into the alveolar process of the maxilla and mandible monocortically and act as an anchor point for MMF wires which passes through the holes incorporated in the specialized screw heads kept 4–5 mm above the alveolar mucosa.
When should MMF be removed?
The patient should be instructed how to release the MMF in case of an emergency. Some surgeons prefer to provide wire cutters to the patient for the period of MMF. During this period, wire fatigue and loosening can occur. The patient should report any loosening of the MMF to the surgeon immediately.
How is mandibular fracture treated?
In general, mandible fractures are treated either closed (maxillomandibular fixation, splinting, modified diet) or open (plates and screws, interosseous wiring, lag screws).
Is MMF closed reduction?
Closed Reduction IMF/MMF is a technique to immobilize the fractured segments of the mandible by externally locking the occlusion into place, using the dentition as a point of stability.
How do you place an Archbar?
The arch bar should be placed between the dental equator and the gingiva. The bar should be trimmed to allow ligation to as many teeth as possible. The bar should not extend past the most distal tooth or protrude into the gingiva as this will be a source of irritation to the patient.
Where do you put IMF screws?
For correct placement, IMF screws must be located in the alveolus avoiding tooth roots….The insertion point is limited by the position of the:
- inferior alveolar nerve.
- infraorbital nerve.
- tooth roots.
What does MMF mean in medical terms?
Mycophenolate mofetil (MMF) to treat immune-mediated neurology conditions. Mycophenolate mofetil (MMF) is an immunosuppressant, that is, it damps down the immune system.
Can a broken jaw heal in 2 weeks?
Take antibiotics as instructed and follow all diet recommendations. With treatment, a broken jaw will typically heal in a month or two. While your dislocated jaw is healing, you should try not to open your mouth very wide for several weeks.
What are Archbars?
Arch bars are comparable to braces which are used to align teeth by an orthodontist, except they are placed by an oral and maxillofacial surgeon in order to align the jaws. The arch bars are secured to the teeth by wires which wrap around the teeth to hold the arch bars firmly in place.
What is Subcondylar fracture?
Subcondylar fractures are, by definition, below the attachment of the joint capsule and in general are devoid of ankylosis. Therefore, maxillomandibular fixation is recommended to be applied for a period of 4 to 6 weeks in most cases.
How are arch bars attached?

What is a mandibular fracture?
Mandibular fracture, also known as fracture of the jaw, is a break through the mandibular bone. In about 60% of cases the break occurs in two places. It may result in a decreased ability to fully open the mouth. Often the teeth will not feel properly aligned or there may be bleeding of the gums.
What are the zones of fracture of the mandible?
The mandible is usually divided into the following zones for the purpose of describing the location of a fracture (see diagram): condylar, coronoid process, ramus, angle of mandible, body (molar and premolar areas), parasymphysis and symphysis. This type of fracture involves the alveolus, also termed the alveolar process of the mandible.
Are mandible fractures associated with non-union and infection rates?
While mandible fractures have similar complication rates whether treated immediately or days later, older fractures are believed to have higher non-union and infection rates although the data on this makes it difficult to draw firm conclusions.
What is the prevalence of mandibular fractures in New Zealand?
