[A study of computer-aided drawing system for individualized ideal arches].
OBJECTIVE
The aim of this study is to devise a computer aided drawing system for individualized ideal arches, to resolve the discommode of manual drawing of Bonwill-Hawley arch charts and and to avoid the non-matching problem when using the universal arch charts.


METHODS
On the basis of drawing principle of Bonwill-Hawley individualized ideal arches, the computer program was written with Visual Basic version 6.0.


RESULTS
The new computer-aided drawing system of individualized ideal arches was based on Windows9X/NT. After the data of mesiodistal diameters of maxillary anterior teeth crown (from mesial surface to distal surface of bracket for canine) were input, a matching individualized ideal arch chart would be drawing using the designed program immediately.


CONCLUSIONS
The computer-aided drawing system of individualized ideal arch can help to draw a matching individualized ideal arch accurately and quickly. This system eliminates the complex and cockamamie process of manual drawing.
