Example

Le Fort type
Le Fort II - pyramidal (floating maxilla)

Result: Le Fort II: a pyramidal "floating maxilla" fracture through the central maxilla, up through the infraorbital rims and medial orbital walls to the nasofrontal region.

The tool opens with these values already filled in. Replace them with your own.

What the result means

Le Fort I
Horizontal "floating palate" fracture across the maxilla above the tooth apices (Guerin).
Le Fort II
Pyramidal "floating maxilla" fracture up through the infraorbital rims and medial orbital walls.
Le Fort III
Craniofacial disjunction ("floating face"): the whole midface separated from the skull base.
