The optical surface scan as an alternative to the cephalograph for soft tissue analysis for orthognathic surgery.
The aim of this study was to compare cephalographs and optical surface scanner images (lasergraphs) by measuring the lipincisor relationship, the nasolabial angle, nasal tip projection, the nasofacial angle, the nasomental angle, and the labiomental angle in pre- and postoperative orthognathic surgery patients. The results showed that the methods were comparable, but the optical surface scan (lasergraph) could be used to greater advantage for pre- and postoperative assessment of soft tissue changes with orthognathic surgery, because of its clarity and 3-dimensional potential.
