Problems solved by technology

[0011] In order to solve the problems of long treatment period, poor initial wearing comfort and frequent replacement of current invisible aligners without brackets, the present invention proposes an active oral aligner including thin-film electro-deformable devices, which can be activated by applying voltage. The thin-film electro-deformable device in the appliance produces controllable bending deformation, thereby actively generating a weak and long-lasting orthodontic force to shorten the period of orthodontic treatment and improve the comfort of the patient

Embodiment 1

[0048] 1) Obtain a digital 3D model of the dentition through intraoral 3D scanning or extraoral 3D scanning of plaster casts. Take full-mouth curved slices by CT, cranial side slices, or use CBCT to obtain jaw and tooth root measurement images or digital 3D models as design references

[0049] 2) Input the scanned initial dentition digital 3D model and relevant design parameter data into the special design software, move the teeth virtually to obtain the best tooth arrangement, and then output it as the target dentition digital 3D model. By comparing the initial three-dimensional digital model with the target three-dimensional digital model, the design movement plan of the misaligned teeth can be obtained, including the movement amount and movement direction.

[0050] 3) Decompose the overall design movement plan of orthodontics into several stages, and then generate the digital three-dimensional model 10 of the middle dentition in each stage. In order to move the teeth 35, th...

[0055] 1) Obtain a digital 3D model of the dentition through intraoral 3D scanning or extraoral 3D scanning of plaster casts.

[0056] 2) Input the scanned initial dentition digital 3D model and relevant design parameter data into the special design software, move the teeth virtually to obtain the best tooth arrangement, and then output it as the target dentition digital 3D model. By comparing the initial three-dimensional digital model with the target three-dimensional digital model, the design movement plan of the misaligned teeth can be obtained, including the movement amount and movement direction.

[0057] 3) Decompose the overall design movement plan of orthodontics into several stages, and then generate the digital three-dimensional model 10 of the middle dentition in each stage. In order to move the teeth 35, the selected anchorage positions are 34 and 36, and the force application positions are the teeth In the middle of 35, the correction force is set to 100g. The r...

Abstract

The invention relates to an active oral appliance and an application method thereof. The active oral appliance is mainly composed of an electro-deformable polymer material which can deform under a small voltage and push a displaced tooth to a design position. By active and uniform producing of a corrective force, the active oral appliance can accelerate the movement speed of the tooth and improvethe movement accuracy, and ultimately reduces the treatment time of orthodontics.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to an active oral appliance including a thin-film electro-deformable device and a corresponding manufacturing and application method. Background technique [0002] In the process of human evolution, the use of tools and changes in food structure have caused the degeneration of chewing organs, while the degeneration rate of teeth is much lower than that of muscles and bones. The result of this unbalanced degeneration has caused malocclusion such as crowded teeth and uneven dentition, which has become an evolutionary disease of human beings. According to relevant statistics, the prevalence of dental and jaw deformities in my country is relatively high, and the highest prevalence in urban surveys has reached 48.9%. If the ideal normal jaw is used as the standard survey statistics, the incidence of dental and jaw deformities is 91.2%. [0003] An oral appliance is a device t...
