Tooth mover for computer-assisting tooth orthodontics

Abstract

The invention relates to a tooth mover for computer-assisting tooth orthodontics, which can most quickly and conveniently move and rotate teeth with strong moving precision and sense of direction. The invention comprises the following steps: 1) initializing a program; 2) initializing a tooth move; 3) reading in a tooth 3D model; 4) choosing a tooth needing to move, displaying by the tooth mover, and presenting the chosen tooth at the crossing point of the moving arrowhead on each direction of the tooth mover; 5) waiting the operation of a user; 6) changing the viewing angle of a tooth displaying window, while the tooth mover follows the changed the viewing angle; clicking the arrowhead on a translation direction or a rotation direction in the tooth mover by mouse, moving the chosen tooth in the tooth displaying window along the assigned direction, or rotating along the assigned rotary shaft and the assigned rotary direction; clicking the icon for changing the rotary shaft in the tooth mover, changing the color of the icon representing the rotary shaft into the color of corresponding rotary shaft, and assigning a new rotary shaft.

Description

1. Technical field: [0001] The invention relates to a computer-aided orthodontic method, in particular to a tooth mover in computer-aided orthodontics, which is applied to computer-aided design and simulation in the field of orthodontics. 2. Background technology: [0002] The application of computer technology in the field of orthodontics has become more and more extensive. One of the applications is to use computer technology to simulate and design orthodontic treatment plans. Teeth need to be moved and rotated when simulating and designing treatment plans. This patent aims at inventing a unique, convenient and feasible technology, which has achieved the most convenient and fastest moving and rotating teeth. In all the movements, the existing movers of this type are divided into two types: control by local frame and control by buttons. Control by local frame is to display the tooth local coordinate system frame on the 3D tooth model to be moved , the center of the frame ...

AI Technical Summary

Problems solved by technology

In all the movements, the existing movers of this type are divided into two types: control by local frame and control by buttons. Control by local frame is to display the tooth local coordinate system frame on the 3D tooth model to be moved , the center of the frame is the center of the tooth, and the bounding box on the frame, the mouse touches the axis of the frame, the tooth moves in this direction, the mouse drags the surface of the bounding box, and the tooth rotates around the center of the frame in the dragging direction , when rotating, the frame rotates accordingly, since the movement is controlled by the mouse, the shaking of the mouse will cause movement errors

Button control is to place movement and rotation buttons in the control dialog box to control the movement of the selected tooth. The sense of direction of movement through button control is very poor, which often causes movement errors
