The prediction of orthognathic treatment is an important part of treatment planning. The manual method of prediction tracing by Epker and Fish had been the gold standard in planning for orthognathic cases. Because it was time-consuming, hence computerized methods gained the popularity. A 19-year-old boy reported with a chief complaint of forwardly placed lower jaw and poor smile for the past 2 years. Examination revealed the mandibular prognathism, obtuse nasolabial angle, posterior cross bite with reverse overjet of 1 mm–0.5 mm of overbite, and bilateral Class III molar and canine relation. There was also the deviation of 1.5 mm midline to left present. On the basis of findings, a diagnosis of mandibular prognathism was made. Treatment planning included an orthognathic surgery (Bilateral sagittal split osteotomy) for the mandibular setback. For the surgical procedure, both manual and computerized methods of prediction were done. Both tracing methods result was same and recommended the mandibular setback of 5 mm.
