Invisible appliance capable of realizing three-dimensional control and manufacturing method thereof

Abstract

The invention discloses an invisible appliance capable of realizing three-dimensional accurate control and a manufacturing method thereof, and the invisible appliance comprises a plurality of invisible fixing piles which comprise bonding parts used for being connected with tooth surfaces and control parts fixed with the bonding parts; invisible archwires are sequentially connected with the invisible fixing piles, the invisible archwires wrap the control portions of the invisible fixing piles and applies force to the invisible fixing piles through elastic force of deformation of the invisible archwires, a plurality of stress faces are arranged on the outer edges of the control portions, and the stress faces abut against the invisible archwires. According to the technical scheme, the advantages of a traditional bracket in the related technical scheme are combined with the advantages of the invisible orthodontic appliance, the elasticity of the invisible archwires replaces a stainless steel dental arch wire, the traditional bracket is replaced with the invisible fixing pile, and therefore control over teeth is achieved by controlling movement of the invisible fixing pile. According tothe technical scheme, the attractive effect of the invisible orthodontic appliance can be achieved, and root control movement of teeth can be achieved.

Description

technical field [0001] The present application relates to the field of orthodontics, in particular to an invisible appliance capable of realizing three-dimensional control and a manufacturing method thereof. Background technique [0002] Orthodontics often use metal and ceramic fixed appliances in clinical use. Metal and ceramic fixed appliances use stainless steel arch wires to be placed in the arch wire slots of the brackets to control the movement of the teeth. However, this type of aligner has an unattractive appearance, is not easy to clean, and is prone to problems such as dental calculus. [0003] In addition to metal and ceramic orthodontic brackets, orthodontic fixed appliances also have invisible removable appliances processed with transparent polymer materials. The invisible removable appliances currently on the market were originally invented and manufactured by Align Technology Company of the United States. The biggest advantage of this type of aligner is that...

AI Technical Summary

Problems solved by technology

At the same time, the inventor found that the invisible appliance solution in the related art is difficult to control the root, and is not suitable for tooth extraction cases and difficult cases, while clinical orthodontic tooth extraction cases often exceed 60%

At the same time, during the use of the same type of aligners, patients must take them off when they eat every day, and they need to brush their teeth and put them back on after eating, which will easily cause interruption of the treatment process
