Embodiment

[0147] Next, embodiments of the present invention will be described in detail with reference to the drawings.

[0148] figure 1 and figure 2 It is a figure which shows the state of the dental inlay measuring processing system of this invention seen from the front and back. figure 1 is the state seen from the SH direction, figure 2This is the state seen from the SF direction. The x, y, and z coordinates in the figure are described as being arbitrarily set based on the orientation of the adjustment device 100 . The direction of the arrow is, for example, the positive direction. In each figure, the direction of the adjusting device 100 is indicated by SH and SF. Since the adjusting device 100 is coupled to the substrate 10 by magnetic force, it is in a state where it can slide and move by applying a slight force if it is on the substrate 10 .

[0149] exist figure 1 Among them, the adjusting device 100 is a tool for rotating and moving the implant model placed on the fix...

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.

Description

technical field [0001] The present invention relates to a measurement and processing system for dental inlays. More specifically, it involves three-dimensional measurement of dental inlays related factors outside the oral cavity through non-contact measurement. Based on the obtained measurement data, the Dental inlay measuring and processing system for making dental inlays by grinding and cutting tooth blanks. Background technique [0002] It is well known that the fabrication of dental inlays using CAD (Computer Aided Design) / CAM (Computer Aided Manufacturing) methods is performed by modeling the shape of the dentition site where the inlay is to be fabricated using conventionally used methods. Next, by three-dimensional measurement of the surface shape of the manufactured model, the shape data is obtained, and the shape data is input into the computer, and with the assistance of the computer, for example, grinding with one or more end mills, disc-shaped milling cutters, etc...
