Maxillary fracture (MX/FX):

Fracture of the upper jaw (maxilla and other facial bones)

Mandibular fracture (MN/FX):

Fracture of the lower jaw (mandible)

Sympyseal separation (SYM/S):

Separation of the two mandibles in the mandibular symphysis; this includes parasymphyseal fractures where the fracture line is partly or completely paramedian to the symphysis; repair of symphyseal separation with wire (circumferential or interquadrant) and/or intraoral resin splinting is abbreviated with

Repair of a jaw fracture (FX/R):

Used when any of the other abbreviations do not describe the jaw fracture repair technique applied

Maxillomandibular fixation (FX/R/MMF):

Fixation that brings together the upper and lower jaws; use

MMF

for devices other than muzzles and splints

Muzzling (FX/R/MZ):

Maxillomandibular fixation using a prefabricated or custom-made muzzle; also used in horses to prevent eating (e.g., post sedation)

Interarch splinting (FX/R/IAS):

Maxillomandibular fixation using intraoral splints (commonly resin that can be reinforced with wire)

Interquadrant splinting (FX/R/IQS):

Fixation using intraoral splints (commonly resin that can be reinforced with wire) between the left and right upper or lower jaw quadrants

Interdental splinting (FX/R/IDS):

Fixation using intraoral splints (commonly resin that can be reinforced with wire) between teeth within a dental arch

Intraosseous wiring (FX/R/WIR/OS):

Fixation using intraosseous wire

Bone plating (FX/R/PL):

Fixation using bone plates

External skeletal fixation (FX/R/EXF):
