発明の名称 (英語) METHOD AND DEVICE FOR DISPLAYING THREE-DIMENSIONAL SIMULATION OF UPPER AND LOWER TOOTH ROWS コモンズ 新技術説明会 実績あり
発明の概要(英語) The purpose of the present invention is to provide a method for rapidly obtaining three-dimensional shape data relating to upper and lower tooth rows, provide a method for calculating distances between the upper and lower tooth rows at high speed from the obtained three-dimensional shape data relating to the upper and lower tooth rows, and provide a method and a device for displaying simulations of the three-dimensional shapes and occlusal regions of the upper and lower tooth rows at high speed on the basis of the abovementioned element technologies. A jaw movement sensor (30) is attached to a subject, and jaw movement data (35) accompanying the jaw movement of the subject is obtained. An impression plate (20) formed by applying an impression material to the upper and lower portions of a rigid flat plate is inserted between upper and lower tooth rows of the subject to which the jaw movement sensor (30) is attached, and the subject performs temporary occlusion. By measuring impression left in the impression material (20) and gauge marks provided in the rigid flat plate using a three-dimensional shape measuring device (25), three-dimensional shape data and gauge mark data relating to the upper and lower tooth rows are acquired. On the basis of the three-dimensional shape data and the gauge mark data relating to the upper and lower tooth rows, jaw position data at the time of the temporary occlusion, and the jaw movement data, simulations of the movements and occlusal regions of the upper and lower tooth rows of the subject are displayed.
