Description

Reinforced anchorage bracket-free invisible correcting device based on Nance arch

Technical Field

The utility model belongs to the technical field of ware is rescued in orthodontic bracket stealthy that does not have in mouth, concretely relates to strengthen anchorage bracket stealthy device of rescuring based on Nance arch.

Background

The bracket-free invisible correction is an orthodontic correction technology integrating digitalization, artificial intelligence and new materials, and wins favor of people due to the characteristics of attractiveness, comfort, visualization of correction process and the like. The method replaces a bracket with an accessory cemented on the tooth, uses a polymer membrane to manufacture a transparent appliance to replace various arch wires, applies a digital model to replace a plaster model, and simultaneously adopts an artificial intelligence technology and three-dimensional design software to simulate the correction process and the correction result to replace manual diagnosis tooth arrangement. With the continuous participation of modern science and technology and the continuous accumulation of clinical data, the adaptation syndrome of bracket-free invisible correction is also continuously expanded. The traditional Nance Arch (Nance Holding Arch) has a three-dimensional direction control function, like a cross palatal bar, posterior molars on two sides of an upper jaw are connected through an Arch body, but different from the cross palatal bar, the Nance Arch takes a hard palate as an anchorage, is usually made of 1.5mm and 1.2mm Arch wires, the Arch wires are bent to the front part of the jaw, a jaw support is made at the Arch part of an jaw, the jaw support can be tightly contacted with a jaw mucosa after being wrapped by materials, and when the molars are stressed, the jaw support limits the movement of the molars, so that the anchorage of the posterior teeth is enhanced.

The bracket-free invisible correction has a relative weakness that the control capability of the three-dimensional movement of teeth is weaker than that of fixed correction, and particularly, the control capability is embodied in the aspects of insufficient torque control of anterior teeth, poor control of roots of teeth moving in a large range, poor covering control during gap closing and the like of a reduction premolar case, and the control capability is closely related to vertical control. The deficiency of vertical control in bracket-free invisible correction is mainly manifested in that correction is not beneficial to dental arch leveling, especially when a reduction patient closes an extraction gap, a roller coaster phenomenon is easy to occur, and the softer the corrector diaphragm, the more obvious the roller coaster phenomenon is, which is related to the factors that the elastic modulus (or rigidity) of a transparent corrector material is smaller, stress relaxation is easy to occur, and the like.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a because Nance bow reinforcing anchorage does not have stealthy device of correcting in groove to solve not enough among the prior art.

In order to achieve the above purpose, the purpose of the present invention is realized by the following technical scheme:

the Nance arch-based enhanced anchorage bracket-free invisible orthodontic device comprises a bracket-free invisible orthodontic device and a Nance arch, wherein the Nance arch is transversely connected between upper jaw molars on the left side and the right side of the bracket-free invisible orthodontic device, the Nance arch comprises two connecting arches and a palate bracket, the palate bracket is connected between the two connecting arches and attached to the palate side of teeth, and the upper jaw molars are first molars or second molars or third molars or first premolars or second premolars.

The Nance arch based enhanced anchorage bracketing-free invisible appliance, the palatal support is in the shape of a ring.

For the Nance arch-based reinforced anchorage bracket-free invisible orthodontic device, the palate bracket is 5-8 mm in outer diameter and 2-3 mm in thickness.

For example, in the Nance arch-based reinforced anchorage bracket-free invisible orthodontic device, the two ends of the connecting arch body and the bracket-free invisible orthodontic device are integrally formed, or the two ends of the connecting arch body are connected with the bracket-free invisible orthodontic device in a snap-in manner.

The reinforced anchorage bracket-free invisible orthodontic device based on the Nance arch is a transparent plastic Nance arch.

The utility model discloses technical scheme's beneficial effect is:

the plastic invisible Nance arch is designed, so that the three-dimensional positions of upper jaw molars (first molars/second molars/third molars/first premolars/second premolars) can be effectively controlled, the bracket-free invisible orthodontic vertical control anchorage is greatly enhanced, and different anchorage effects are increased by using the strength of tongue muscles during swallowing; the method can utilize the digital customized design of the invisible orthodontic device to design the connection position of the Nance arch at each step according to the movement change of teeth, further more efficiently and quickly complete the invisible tooth extraction case, and is worth popularizing.
