What is the most common fractured part of the mandible?
Mandibular fractures are typically the result of trauma. This can include a fall onto the chin or a hit from the side. Rarely they may be due to osteonecrosis or tumors in the bone. The most common area of fracture is at the condyle (36%), body (21%), angle (20%) and symphysis (14%).
Which of the following is the main complication of a mandibular fracture?
Mandible fracture complication rates range from 7 to 29% and have been correlated to fracture severity, injury site, and the number of involved sites. The most common complications include infection, hardware failure, osteomyelitis, nonunion, malunion, and wound dehiscence.
How do you treat a mandibular fracture?
Treatment of Mandibular Fractures
- Resting your jaw. This requires you to avoid opening your jaw except to consume – but definitely not chew – soft foods and liquids.
- Wiring your mouth closed. This stabilizes your jaw joints as the bones heal.
- Surgery for more severe breaks.
What are the classifications of mandibular fracture?
A new classification for mandibular fractures
| Class I | Single condyle |
|---|---|
| Class IIc | Class II and condyle |
| Class III | Body/Parasymphysis/Symphysis |
| Class IIIc | Class III and condyle |
| Class IV | >1 fracture not including either condyle |
Can a mandibular fracture heal on its own?
If you have a minor fracture, it can heal on its own. You may only need pain medicines. You will probably have to eat soft foods or stay on a liquid diet for a while. Surgery is often needed for moderate to severe fractures.
What is the most commonly injured nerve following mandibular fracture?
The most frequent fracture occurred in mandible followed by zygoma and the most injured nerve was inferior alveolar nerve followed by infraorbital branch of trigeminal nerve.
Is mandibular fracture an emergency?
This study suggests that fractures of the tooth-bearing portion of the mandible should no longer be considered as an emergency that must be treated within a 6-hour delay.
Do all jaw fractures need surgery?
Depending on the extent of the break, treatment for a jaw fracture may require surgery. Clean breaks may heal on their own while your jaw is immobilized, while multiple fractures will likely require surgical repair.
What nerve passes through the mental foramen?
mandibular alveolar nerve
The mandibular alveolar nerve traverses the mandibular canal to emerge at the mental foramen as the mental nerve.
How painful is a broken mandible?

How serious is a fractured jaw?

How is dentoalveolar fracture diagnosed?
The panoramic radiograph and intraoral films, including occlusal radiographs, can provide a good initial evaluation of mandibular trauma. The panoramic radiograph allows visibility of the entire mandible, including the condyles, dentoalveolar complex, and dentition.
What happens when mental nerve is damaged?
The most common clinical manifestation of these insults is the paresthesia of the inferior alveolar nerve or mental nerve paresthesia. Paresthesia usually manifests as burning, prickling, tingling, numbness, itching or any deviation from normal sensation.
What is a mental spine of the mandible?
A medial view of the mandible showing the attachments of geniohyoid and genioglossus. [edit on Wikidata] A mental spine is a small projection of bone on the posterior aspect of the mandible (lower jaw bone) in the midline.
What is a mandible fracture?
Mandible fractures are regularly encountered by plastic surgeons and account for a significant portion of maxillofacial injuries.
Which is a favorable fracture of the mandibular angle?
Upper left shows a mandibular fracture proximal to the angle. This is a favorable fracture. Lower right shows an unfavorable fracture of the mandibular angle with forces resulting in an unstable fracture. Figure 5. Panorex of angle fracture.
What are the most common fractures of the mandibular condyle?
The most common mandible fractures in children involve the condyle (40–70%),7778which is considered a primary growth center of the jaw. Direct trauma to the anterior mandible can result in proximal transmission of force, leading to injury of the mandibular condyle. Forces transmitted to this region often result in intra-articular fractures.
