Invisible orthodontic bimodal accessory

Abstract

The invention discloses an invisible orthodontic bimodal accessory. The invisible orthodontic bimodal accessory is provided with a tongue side surface and a lip side surface which are oppositely arranged, a mesial surface and a distal surface which are oppositely arranged, and a occlusal side surface and a gingival side surface which are oppositely arranged, wherein the tongue side surface is adhered to a tooth surface; the occlusal side surface is of a concave smooth curved surface structure; the gingival side surface is of a planar structure; and the gingival side surface is arranged towards one side of the gingival. The gingival side surface of the invisible orthodontic bimodal accessory is of the planar structure, and two sides, towards the mesial surface and the distal surface, of the occlusal side surface are respectively provided with two smooth bulges to form the concave smooth curved surface structure, namely a bimodal structure, so that the surface contact area is increased, and the retention property is enhanced. Moreover, the contact surfaces in multiple directions are formed with an appliance, the orthodontic force in multiple directions can be effectively transferred, and tooth movement is controlled in multiple directions and multiple angles.

Description

technical field [0001] The invention relates to the technical field of orthodontic treatment appliances, in particular to an invisible orthodontic bimodal attachment. Background technique [0002] Invisible orthodontics has increasingly become a trend in the development of contemporary orthodontics. The invisible aligner is a transparent elastic material movable orthodontic device designed and manufactured by computer. It is a series of continuous multiple braces, which achieve the purpose of orthodontics through continuous small-scale tooth movement. In order to enhance the retention of the clear aligner and the control of the teeth, attachments, such as rectangular attachments and oval attachments, are often bonded to the teeth. [0003] The following problems exist in the accessories commonly used in clinic: [0004] 1. The traditional rectangular attachment has only 5 planes in contact with the appliance, and the control ability is weak. Each contact surface is a plan...

AI Technical Summary

Problems solved by technology

However, the traditional rectangular attachments of mandibular teeth are often unable to be placed close to the occlusal position due to the interference of the cusps, which has a great impact on the performance of the attachments.

[0005] 2. The elliptical attachment has poor retention, weak control over the teeth, and the teeth are easy to derail

But the ability to control the teeth is weak, the retention performance is poor, and it is easy to derail during the treatment process, which affects the direction and speed of tooth movement
