Background technique

The traditional orthodontic appliance is to bond small iron sheets called brackets on the teeth, and then ligate the orthodontic archwires to move the teeth to achieve the purpose of correction. However, because there are many orthodontic devices on the teeth, it gives people the feeling of "iron mouth and steel teeth". At the same time, if oral hygiene is not well maintained, it may cause oral damage such as gingival inflammation, demineralization and discoloration of teeth, which makes many patients, especially adult patients, fearful of "correction". As a result, invisible orthodontic technology and orthodontic appliances without brackets came into being. Invisible correction without brackets is the use of today's advanced tomographic scanning technology to enter the 3D data of the obtained plaster model of the jaw and jaw for 3D reconstruction of the model; the reconstructed digital model can be directly rotated and observed in various directions on the computer. Zoom in and zoom out, and can automatically measure teeth, dental arch, base bone and other measurement items. On the basis of this research, combined with visualized 3D image processing and 3D laser rapid prototyping technology, it is possible to simulate clinical orthodontic design and tooth movement methods and steps, and perform visualized 3D correction of dental and jaw deformities. The jaw model is subjected to three-dimensional rapid laser forming, and then the transparent invisible aligners of each stage are pressed on the formed resin model. Bracket-free invisible orthodontics can be corrected without wires and brackets, so that others can't see that you are wearing braces, and it doesn't affect the appearance. You can take off the braces by yourself. However, through clinical application, it is found that the protrusion patients who need torque control for adduction of the anterior teeth cannot provide enough torque, and often cannot achieve the desired effect.
