Reliability and feasibility of prediction tracing in orthognathic surgery.
Review of 40 prediction tracings showed that 60% of these showed inaccuracy when compared with post-operative tracings. 33% of inaccurate prediction tracings were associated with inaccuracy of surgery. 83% of all prediction tracing for planning bimaxillary procedures and 40% of all prediction tracing for planning unimaxillary procedures were inaccurate. Some factors which may be responsible for inaccuracy of prediction tracing are discussed.
