Embodiment 1

[0024] Embodiment 1 The manufacturing method of the invisible aligner based on shape memory material according to the present invention comprises the following steps:

[0025] ⑴Obtaining the patient's oral data: scan directly with an intraoral scanner, or perfuse a plaster model after oral impressions, and then scan the plaster model with a laser scanner; or perform CT scans for patients with special diseases such as severe dentition deformities to obtain patient data Jaw and root data;

[0026] (2) Determine the parameters of the three-dimensional model of the oral cavity: input the patient's oral data obtained in step (1) into the orthodontic treatment tooth arrangement software, and then determine the restoring force provided by the invisible appliance according to the thermodynamic model of the shape memory material; according to the amount of tooth movement and the invisible orthodontic The restoration force of the appliance determines the treatment period of a single cle...

Embodiment 2

[0036] Example 2 An invisible appliance is made according to the method described in Example 1, including a body made of biosafety shape-memory material, the body has a cavity set on the patient's dentition, the The cavity has a shape suitable for covering the patient's dentition when the temperature is above 37 degrees Celsius, and the cavity has a memory shape for providing the corrective force required for tooth movement at the oral temperature.

[0037] The invention proposes a manufacturing method of an orthodontic invisible appliance based on a shape memory material and the invisible appliance. The shape memory material of the invisible aligner is a transparent polymer material with shape memory function and biosafety. The material will return to its original shape under the oral temperature environment, providing a certain shape recovery force, not just elastic deformation force . The doctor designs the steps of orthodontic treatment according to the patient's oral con...

Abstract

The manufacturing method of the invisible aligner based on shape memory material and the invisible aligner thereof comprise the following steps: 1) collecting the oral data of the patient; 2) determining the parameters of the three-dimensional model of the oral cavity; 3) constructing the three-dimensional model of the invisible aligner; The three-dimensional model of the aligner is used to make the invisible aligner; 5) The invisible aligner obtained in step (4) is soaked in water above 37 degrees Celsius and softened, and quickly worn on the patient's dentition; under the oral temperature environment, it will gradually return to A shape in memory for providing the orthodontic force required for tooth movement; also includes clear aligners made according to the above method. The invention has the beneficial effects of solving the trouble of frequent replacement of traditional invisible aligners, shortening the correction process, saving treatment cost and making correction accurate.

Description

technical field [0001] The invention relates to a manufacturing method of an orthodontic invisible appliance based on a shape memory material and the invisible appliance. Background technique [0002] In recent years, with the improvement of the quality of life, people pay more and more attention to the beauty of teeth, and the orthodontic treatment technology is gradually accepted by people. Traditional orthodontics uses a fixed appliance composed of a nickel-titanium alloy arch wire and a metal bracket. Although this appliance can achieve a good therapeutic effect, it is not beautiful and comfortable enough. People hope that the appliance can not only straighten the teeth well, but also have a good aesthetic effect, and the invisible appliance came into being, which can well avoid the phenomenon of "iron teeth and steel teeth". At present, invisible aligners mainly use elastic transparent polymer materials. This invisible aligner is passively applied during the orthodont...
