Title:
DENTAL PROSTHETIC MATTER PRODUCING DEVICE
Document Type and Number:
Japanese Patent JP3455793
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To easily grasp the recovering amount of grinding dust by providing a recovering amount detecting means for detecting the amount of grinding dust generated at the time of machining a prosthesis in the case of machining the prosthesis based on shape data by a multiaxes machining means, thereby grasping the amount of the grinding dust in parallel with the production of the prosthesis.
SOLUTION: At the time of producing a dental prosthesis, a three-dimensional shape measuring instrument 1 first measures the three-dimensional shape of a pier tooth needing prosthetic and restoration, a proximal tooth, the engagement face of the antagonist of the pier tooth, etc. Next, a controller 2 automatically designs the shape of the prosthesis from its shape data, automatically generates the NC program of a multiaxes machining means 3 and then controls the means 3 to grind a material to be machined. At this time recovering amount detecting means 4 calculates the volume V of the prosthesis from shape data of the automatically designed prosthesis and a recovering amount arithmetic means 5 calculates the grinding dust amount at the time of machining the prosthesis by the means 3 and outputs the result to a recovering amount recognizing means 6.
