Embodiment Construction

[0023] Such as figure 1 As shown, in the early stage of data acquisition, the dentist first obtains the patient’s dental model and reproduces the plaster male model; then the CT tomography system scans the plaster male model of the teeth to obtain scanned tomographic image data or adopts The laser measuring instrument measures the dental plaster model to obtain laser measurement data.

[0024] In the stage of intelligent modeling of braces, the software first reconstructs the three-dimensional digital model of the teeth; then performs single tooth segmentation; then realizes computer-aided virtual tooth correction through the interactive dialogue between the dentist and the computer, and automatically generates correction series through motion planning and gradient technology 3D digital model of braces.

[0025] In the braces manufacturing stage, the tooth series digital model generated in the previous step is used as input data, and the corresponding series of tooth models a...

Abstract

A computer aided hidden tooth deformity correcting system is composed of a data acquisition subsystem, an intelligent tooth sleeve modelling subsystem, transparent tooth sleeve manufacture subsystem and data bus.

Description

technical field [0001] The invention relates to a tooth invisible orthodontic system, specifically, a computer-aided tooth invisible orthodontic system. It belongs to the field of medical application technology. Background technique [0002] The traditional orthodontic method is to use a fixed orthodontic appliance (metal orthodontic appliance), a series of small metal pieces are glued to the surface of the teeth, and the desired effect is achieved by adjusting the width and tightness of the metal wire. However, metal orthodontic appliances have the following disadvantages: the protruding shape of metal orthodontic appliances affects personal appearance, and many people mistakenly believe that "braces" are only for children, and it is difficult for adults to adopt them. Metal orthodontic appliances are easy to cause oral wear , cause oral discomfort, and many people are reluctant to use it. Using metal braces affects normal diet. During orthodontic treatment, sticky foods s...
