AIM: The purpose of this study is to introduce our newly developed 3D integration system for computed simulation of facial, skeletal, and occlusal changes with orthognathic surgery, and its clinical application.<BR>MATERIAL AND METHOD: The system is composed of the following three non-contact measuring units: a facial analyzer using coded pattern projection (OGIS, RFX IV), an X-ray CT machine (SIEMENS, SOMATOM PLUS S), and a dental model analyzer using laser scanning (UNISN, VMS250R). To construct common 3D coordinates, the face bow having three ceramic balls used as standard points was set on the maxillary dental arch for obtaining 3D information from each measuring unit. The 3D coordinate values were sent to the workstation (KUBOTA, Titan 2) and integrated into the common 3-D coordinate system by superposition based on the standard points of the face bow.<BR>RESULT: 1) Compared with measured values by a contact 3D measuring unit (MITSUTOYO, MXF203), the measuring reliability in the 3D distance was 1.61±0.81mm in the facial analyzer, 0.56±0.25mm in the X-ray CT machine, and 0.13±0.08mm in the dental model analyzer. 2) Measurement reliability of the predicted skeletal change based on the occlusal change was 1.20±0.36mm in the 3D distance.<BR>In clinical application, 3D skeletal and facialgraphics could be simulated based on predicted occlusal changes.<BR>CONCLUSION: 3D information from the different measuring units could be integrated with high accuracy into our 3D integration system, and its clinical applicability was satisfactorily confirmed.
