<p>A dentist scans a patient's oral cavity using a three-dimensional scanner (1). Then, a computer main body (2) generates a three-dimensional shape model of patient's teeth according to scanned data and performs placement of a bracket (B) and shape designing of a transfer tray (tray (T), hereafter) in a virtual three-dimensional space. Three-dimensional shape data relative to the tray (T) is outputted to a tray creation apparatus, and the tray (T) shaped corresponding to the data is created. Placement data of the bracket (B) is outputted to a bracket fixing apparatus (6), which is automatically controlled to fix the bracket (B) at a precise place of the tray (T) according to the placement data. The bracket (B) may automatically be placed according to a placement rule, example data, etc.</p> |
