Soft lining type invisible tooth aligner and manufacturing method thereof

Abstract

The invention relates to the technical field of tooth alignment, in particular to a soft lining type invisible tooth aligner. The aligner comprises an aligner body; a soft lining made of a die material is arranged on one side, making contact with teeth, of the aligner body. The soft lining made of the die material is arranged on one side, making contact with teeth, of the aligner body, the component of the die material is resin, the soft lining fills up the gap between teeth and the aligner body, the retention of the aligner body is increased, so that the aligner body is firmly attached to theteeth, looseness and falling of the aligner body are avoided, contradiction between an elastic material and a rigid material of the aligner body is relieved, and the tooth alignment effect is improved.

Description

technical field [0001] The technical field of orthodontics of the present invention is specifically a soft-lined invisible orthodontic appliance and a manufacturing method thereof. Background technique [0002] Teeth are a structure present in many vertebrates, and generally speaking, teeth are white and hard. The various shapes of teeth are suitable for various purposes, including tearing, grinding food. Some animals, especially carnivores, use their teeth as a fighting weapon. With the establishment of human civilization, the pronunciation of various languages ​​has developed into diversification. Language pronunciation is very dependent on the cooperation of teeth, tongue and oral cavity, and it is applied to speaking and singing in human life. Teeth cleanliness is even related to social activities and status.

AI Technical Summary

Problems solved by technology

[0003] Tooth movement after wearing invisible aligners without brackets often fails to achieve the pre-designed result, which means that the tooth movement cannot keep up with the shape change of the aligner, that is, the designed force value cannot be fully transmitted to the moved teeth. The problem is that There is a contradiction between the elasticity and rigidity of transparent elastic materials. The high elasticity leads to poor rigidity, while the high rigidity leads to poor elasticity. The strength of the material is poor in continuity, so the tooth movement often fails to achieve the pre-designed result.
