Jaw abnormality sagittally divides the face into five equal parts: It is insufficient to derive at a diagnosis of jaw deformity solely based on the clinical examination. Hence, additional information is gathered from diagnostic tests, which may include dental model analyses and radiographic imaging studies.

Jaw wiring lower teeth in a figure-8 pattern. The wiring is removed periodically to allow the jaw joints to move freely, especially in the vertical direction. The procedure is not invasive and does not require anesthesia. Unlike inter-maxillary fixation, OJW does not keep the upper and lower teeth in contact. The sole purpose of the wiring is to limit the extent to which the jaws may open. In the resting position, the teeth are parted 2–4 millimeters, with the lips lightly touching.
