| Research Abstract |
This study investigated stimulation of soft tissue changes following orthognatic surgery using a 3 dimentional grahic model and analyzed the distribution of displacement.
Non-contact and accurate 3-dimensional profile measurement is highly desirable in the fields of human engineering and also orthodontic treatment. Important points of the 3-dimensional profile measurement are how to obtain all 3-dimensional data as fast as possible, and how to convert all these data to 3-dimensional coordinates. We show one technique enabling fast 3-dimensional measurement of human head. As mentioned before, the 3-dimensional profile of the human face (cranio-maxillofacial) is a concem in plastic and oral surgery. The principle of our measuring system is based on the slit ray projection method. Due to this reference table, fast data convention becomes possible without the use of high-speed arithmetic processor such as digital signal processors.
