A non-bracket invisible appliance and its manufacturing method

A non-bracket invisible appliance manufacturing method, comprising acquiring data of the patient mouth, the patient's mouth 3D model data based on the oral cavity, comprising a three-dimensional model of teeth and gums data transactions; design treatment schemes, the bit teeth to be corrected to adjust correction target position, obtaining dental model; generating a cut line on dental model: a rapid prototyping method or 3D printing manner molded into a solid 3D models of dental model, with a vacuum laminator in a manner to cover the diaphragm entity the dental model; diaphragm covered with the solid line to cut the dental model 3D models of the cutting path after cutting is completed, a release film formed appliance. No bracket invisible appliance manufactured by the above method, too. The present invention has a high efficiency, and the appliance can withstand large forces, it is not easily broken advantages.
