Since the teeth are supported by the jaws (upper jaw- maxilla, lower jaw-mandible), the relationship of upper and lower jaws will affect how teeth occlude. If this relationship deviates from normal range, an ideal occlusion will be difficult to achieve with merely orthodontic treatment. In that case, a surgical correction (i.e. orthognathic surgery) will be needed to help correct the jaw position.
