METHOD OF DESIGNING CUSTOM ARTICULATOR INSERTS USING FOUR-DIMENSIONAL DATA

摘要

The present invention provides methods for designing dental articulator inserts from 3d dental data (4d datasets). These 4d datasets may be used directly to provide a jaw motion model suitable for enhanced CAD or, they may be used to derive mathematical expressions that are then used to design dental articulator inserts. The methods of the invention are based on acquiring time-based 3d data representing the upper and lower teeth. Each datum in the 4d dataset may therefore contain an accurate record of the relationship between the upper and lower arch in three dimensions.
