Problems solved by technology

[0002] Invisible orthodontics is a technology that uses computer-aided design of transparent plastic invisible braces for orthodontic treatment. In the process of using invisible braces for tooth extraction cases, due to the softness and insufficient rigidity of the invisible braces, it is easy to cause the molars to lean forward. The roller coaster effect of occlusal deepening makes the efficiency of invisible braces in the treatment of tooth extraction cases significantly lower than that of traditional fixed appliances, which greatly limits the use of invisible braces in tooth extraction cases

Embodiment 1

[0028] This embodiment corresponds to the case after the maxillary canines were extracted, using the following methods: figure 1 The force-applying device shown includes anchorage 1, invisible braces and several force-applying elements. The invisible braces are composed of the upper-jaw invisible braces 2 and the upper-jaw invisible braces 3, and the force applying element adopts an elastic rubber ring.

[0029] Anchorage 1 is made of metal material, and consists of a bow-shaped rod adapted to the inner cavity of the palate and arms arranged at both ends of the bow-shaped rod, see figure 2 . At least one first connecting portion and several second connecting portions are provided on the bow-shaped rod for respectively connecting with the upper palate and the force-applying element. The first connection part of this embodiment is the implant hole 11, which is used to fix the anchorage 1 on the palate of the case through the implant nail, and the support arm is provided with ...

Embodiment 2

[0034] The structure of the force applying device in this embodiment is basically the same as that in Embodiment 1, the difference is that two planting holes 11 are arranged in the middle of the anchorage 1, and the two planting holes are arranged symmetrically along the center of the anchorage 1, see image 3 , the palate anchorage 1 is in the shape of a long strip. Since each patient’s palate has different heights and shapes, the device in this embodiment adopts digital personalized design and printing, so that the palate anchorage 1 is bent along the length direction to fit the shape of the palate. Curved surface, good workmanship, high patient comfort.

[0035] The maxillary invisible braces 2 are provided with a first gap 21 corresponding to the lingual side of the maxillary first molar, see Figure 4 , combined with figure 1 As shown, the two ends of the anchorage 1 pass through the first gap 21 and are fixedly connected with the first molars on both sides of the upper ...

Abstract

The invention relates to a force application device and method based on invisible correction of a tooth extraction case. An anchorage is arranged on the palate, and a plurality of force application elements are arranged on the anchorage; traction is conducted on the two sides of the upper jaw invisible tooth socket through a force application element so as to apply lip and tongue side traction force enabling the upper jaw anterior teeth to adduct; traction is performed on the first molars on the two sides of the lower jaw through the force applying element to apply forward-leaning-resisting traction force for preventing the molars of the lower jaw from leaning forward; lip and tongue side traction force is applied to an upper jaw invisible tooth socket through anchorage, the traction force provides vertically upward pressing force and adduction force for the invisible tooth socket and upper anterior teeth, fitting of the tooth socket and opening of occlusion of the anterior teeth are facilitated, and the correction efficiency is improved; and traction force is applied to the first mandibular molars on the two sides through anchorage to stabilize the relation between the upper and lower molars and ensure that the mandibular molars do not incline forwards.

Description

technical field [0001] The invention relates to a labial-lingual combined force application method and device for invisible correction of tooth extraction cases, and belongs to the technical field of orthodontics. Background technique [0002] Invisible orthodontics is a technology that uses computer-aided design of transparent plastic invisible braces for orthodontic treatment. In the process of using invisible braces for tooth extraction cases, due to the softness and insufficient rigidity of the invisible braces, it is easy to cause the molars to lean forward. The roller coaster effect of occlusal deepening makes the efficiency of invisible braces in the treatment of tooth extraction cases significantly lower than that of traditional fixed appliances, which greatly limits the use of invisible braces in tooth extraction cases. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention provides a labial-lingual combi...
