Anchorage traction composite accessory and invisible correction device

Abstract

The invention provides an anchorage traction composite accessory and an invisible correction device. The anchorage traction composite accessory comprises a body and a traction hook, wherein the body and the traction hook are fixed, the traction hook is exposed, the body comprises a mounting part for containing the traction hook and an anchorage part for providing anchorage, and the anchorage partis positioned at one side of the mounting part. In use, the mounting part is positioned at the lower side, the anchorage part is positioned at the upper side, and the anchorage part faces the mesio-occlusion direction of the dentition. The anchorage traction composite accessory and the invisible correction device provided by the invention can simultaneously perform tooth intrusion or extrusion andpull traction, thereby shortening the correction time.

Description

technical field [0001] The invention relates to an accessory used in dental orthodontics, an appliance template for making the accessory and an invisible appliance used in conjunction with the accessory. Background technique [0002] During orthodontics, various orthodontic devices are used to adjust the coordination between facial bones, teeth, and maxillofacial nerves and muscles, that is, to adjust the relationship between the upper and lower jaws, between the upper and lower teeth, between the teeth and the jaws, and between the teeth and the jaws. The abnormal relationship between the nerves and muscles that connect them, the ultimate goal of correction is to achieve the balance, stability and aesthetics of the oral and jaw system. The correction of malocclusion mainly relies on wearing appliances inside or outside the oral cavity, exerting appropriate biological force on the teeth, alveolar bone and jaw, and causing them to move physiologically, thereby correcting malo...

AI Technical Summary

Problems solved by technology

However, after the incision of the gingival side of the accessory groove, the binding force between the accessory and the accessory groove is lost, so the role of the accessory as an anchorage is lost

In other words, the anchorage function and the traction function cannot coexist on the same accessory

[0005] Therefore, for complex cases that require both tooth elongation and depression, as well as tooth extraction for tooth alignment, the depression, elongation and traction can only be performed step by step, such as elongation and depression first, and then traction; or first Perform opposite pull and traction, and then perform elongation and depression; step-by-step correction results in greatly prolonged treatment time
