Mandibular Fractures in LAs Flashcards
true or false: NEVER remove loose teeth until fracture has healed
true
techniques used for mandibular fracture repair in LAs (4)
-intraoral wiring -tension band wiring to teeth -external fixation -plates
repair of fractures to diastema of mandible
tension band wiring of cheek teeth (PM 2, 306, 406) to incisors under general anesthesia +/- lag screw

repair of mandibular body fractures
external skeletal fixators
- unilateral fracture: type 1 ESF
- bilateral fracture: type 2 ESF

why is prognosis good for mandibular fractures?
-good blood supply -non weight bearing -unilateral fractures supported by intact side (natural splint)
fractures in incisor area are almost always…

aftercare for mandibular fractures
-no diet changes needed -lavage mouth daily -NSAIDs -+/- antibiotics -remove implants after 6-8 weeks
indications for using mandibular plate +/- tension band wire
-fracture of both body and vertical ramus -fracture of caudal aspect of body
cons of using mandibular plate +/- tension band wire technique (4)
-can only be placed on compression side -screw placement tough because of long roots -parotid duct in way -most mandibular fractures are open -> can be nidus for infection
