Title:
DENTAL INLAY GRAFT MEASURING/MACHINING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2009/035142
Kind Code:
A1
Abstract:
A dental inlay graft measuring/machining system comprising three-dimensional
shape making means for creating shape data on a virtual tooth row including the
shapes of a loss part of a tooth and its adjacent tooth and shape data on the opposite
occluding surfaces of the opposite teeth opposed to the virtual tooth row, virtual
inlay graft fabricating means for making a virtual inlay graft shape from the
shape data on the virtual tooth row and the shape data on the opposite occluding
surfaces, occlusion adjusting means for virtually combining the shape data
on a ready-made inlay graft shape for inlay graft formation similar to the virtual
inlay graft shape with the shape data on the virtual inlay graft shape and adjusting
the combined data, subjecting the shape data on the virtual tooth row and the shape
data on the opposite occluding surfaces to contact, mastication, and adjustment,
subjecting the shape data on the opposite occluding surfaces to virtual movement,
subjecting the shape data on the virtual tooth row to virtual jaw movement, thereby
displaying the state of the jaw movement on a monitor, and determining the most
suitable inlay graft shape of the virtual tooth row, and block machining means
for machining a block to be machined according to the most suitable inlay graft
shape data to make a dental inlay graft.
