Comminuted fracture
Greenstick fracture AKA
Incomplete fracture
If muscles pull a fracture together.
Favorable fracture.
Tetanus prophylaxis and antibiotics are indicated in this kind of fracture bc the bone is exposed to the external environment.

Principles of fracture management
Reduction and Fixation
Refers to open surgery to set bones.
Cut a person open to set the bones.
Open reduction
Refers to using implants in the bone to bring the fracture segments together.
Internal fixation
Refers to using braces or other apparatus on the external surface of the body to bring the fractured segments together.
External fixation
Most commonly used reduction technique in dentistry.
Open with internal fixation
An appliance that goes from one side of the arch to another to fixate jaw fractures.
Archbar
Most common mandibular fracture.
Condyle (29%)
Mandibular fractures from most to least common:
1) Condylar
2) Angle
3) Symphysis
4) Body
Advantage of a closed reduction.
Less surgical complications.
A piece of plastic that’s wired to the teeth to hold the mandible together.
Splint
T/F: Can use the patient’s dentures to splint their jaw together.
