There are many documented problems associated with these traditional techniques, which have often led to less than optimal surgical outcomes. Whereas surgical techniques have seen rapid improvement in the last 50 years, e.g., rigid fixation, resorbable materials, and distraction osteogenesis, available orthognathic surgical planning tools have remained unchanged since the 1960s, e.g., two-dimensional (2D) cephalometry, prediction tracing, and stone dental model surgery.
However, due to the complex nature of the dentofacial anatomy, orthognathic surgery often requires extensive presurgical planning. Each year thousands of patients elect to undergo various orthognathic surgical procedures. Orthognathic surgery is a surgical procedure to correct dentofacial (jaw) deformities.
