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.

Embodiment 1

[0023] see figure 1 , in an embodiment of the present invention, a soft-lined invisible dental appliance includes an appliance body 1 and a soft lining 2; the appliance body 1 is a ring-shaped structure adapted to the teeth, and the appliance body 1 is made of elastic transparent material, and the side of the appliance body 1 in contact with the teeth is provided with the soft lining 2, the soft lining 2 is made of a substitute material, the composition of the substitute material is resin, and the soft lining 2 is filled with the teeth and the appliance The gap between the body 1 not only increases the retention of the appliance body 1, but also makes the appliance body 1 firmly attached to the teeth, prevents the appliance body 1 from loosening and falling off, and buffers the elastic material and rigidity of the appliance body 1. The contradiction between the materials improves the orthodontic effect;

[0024] Specifically, in this embodiment, the soft lining 2 is connected...

Embodiment 2

[0030] A soft-lined invisible orthodontic appliance, comprising the soft-lined invisible orthodontic device described in Embodiment 1.

[0031] The present invention is provided with a soft liner on the side where the appliance body is in contact with the teeth. The soft liner is made of a substitute material, the composition of which is resin, and the soft liner fills the gap between the teeth and the appliance body, increasing It ensures the retention of the appliance body, makes the appliance body firmly attached to the teeth, prevents the appliance body from loosening and falling off, and buffers the contradiction between the elastic material and the rigid material of the appliance body, improving the orthodontic effect.

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. [0003] Tooth movement after wearing invisible aligners without brackets often fails to achieve the pre-designed result, which means that the tooth movement can...
