Description
Technical Field
The utility model relates to a technical field is rescued to the tooth deformity, concretely relates to ware is rescued in stealthy that can prevent to extract tooth and empty.
Background
In the existing invisible orthodontic process, in order to solve the crowdedness of dentition and obtain more gaps, tooth extraction is often needed. However, after tooth extraction, the Invisalign company only proposed the G6 design for the case of tooth extraction in which the first bicuspid tooth was extracted, because the invisible appliance force application process is not continuous, often resulting in the tipping of the adjacent teeth in the extraction area toward the extraction area. There is the doctor to adopt at tooth surface bonding protruding form part, design the recess on the stealthy correction of support groove, the axle inclination of the adjacent tooth of disappearance tooth is controlled through the cooperation between arch and the recess, but this protruding form part is relatively poor to the control of axle inclination, the main reason is because the effort of stealthy correction ware is constantly decaying, and stealthy correction ware mainly acts on the dental crown, make the tooth root remove through removing the dental crown, and the tooth root removes and lags behind the dental crown and removes, when the dental crown because the effort of stealthy correction ware moves in place, stealthy correction ware effort has been attenuated this moment, can't continue to move the tooth, but the tooth root of this moment does not move in place, through many sets of teeth, will lead to the tooth of adjacent area to topple over to the area of extracting teeth.
For example, chinese patent publication No. CN204951190U discloses an orthodontic device suitable for cases of tooth extraction, which prevents falling by providing an insert on an adjacent tooth of a missing tooth and fixing the adjacent tooth of the missing tooth with a U-shaped plate. However, in the technical scheme, the gap is formed on the appliance, the integrity of the appliance is damaged, the mechanical property of the appliance is changed, and the moving effect of teeth cannot reach the expectation; while being operationally complex.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome not enough among the prior art, provide a can prevent to pull out stealthy of tooth and rescue the ware, avoid destroying stealthy wholeness of rescuring the ware, and compare in traditional rescuring the ware and have easy and simple to handle, receive the advantage that seam speed is faster.
In order to achieve the above purpose, the utility model adopts the following technical scheme to realize:
an invisible appliance capable of preventing tooth extraction from toppling comprises an invisible appliance body and a root control accessory, wherein the invisible appliance body is formed by positively pressing a transparent high polymer material on a 3D printed tooth model, cutting the invisible appliance body and is used for being worn on teeth;
the two sets of root control accessories are respectively fixed on the opposite side surfaces of adjacent teeth on the two sides of the tooth extraction area, the two sets of root control accessories are both provided with magnetism, and the magnetism of the root control accessories on the opposite side surfaces of the adjacent teeth on the two sides of the tooth extraction area is opposite, so that the invisible appliance body worn on the teeth generates repulsive acting force.
Preferably, the surface of the root control attachment is smaller than the crown surface of an adjacent tooth in the extraction area.
Compared with the prior art, the invisible orthodontic appliance provided by the utility model can continuously apply force to the adjacent tooth in the tooth extraction area in the invisible orthodontic process, and acts on the dental crown near the tooth root of the adjacent tooth, thereby realizing the integral movement of the tooth; the technical scheme does not damage the integrity of the invisible orthodontic appliance, shortens the closing time of the gap of the tooth extraction area, accelerates the orthodontic process and effectively solves the problem of toppling of adjacent teeth in the tooth extraction area; furthermore, the utility model provides a ware is rescued in stealthy simple structure, convenient operation.

fig. 2 is a schematic structural view of an invisible appliance for preventing tooth extraction from toppling, according to an embodiment of the present invention;
the reference numbers in the figures illustrate: 1-tooth extracting area, 2-first adjacent tooth, 3-second adjacent tooth, 10-invisible appliance body, 20-root control accessory, 20 a-first root control accessory and 20 b-second root control accessory.
Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
It should be noted that, in the present invention, when an element is referred to as being "fixed" to another element, it may be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.
Fig. 1 is a schematic view of a tooth after tooth extraction; wherein, two sides of the tooth extracting area 1 are respectively corresponding to a first adjacent tooth 2 and a second adjacent tooth 3; the force application process of the invisible appliance is not continuous, so that the problem that adjacent teeth of the tooth extraction area 1 incline towards the tooth extraction area 1 is easily caused.
In order to solve the above technical problem, the invisible orthodontic appliance provided by the present invention comprises an invisible orthodontic appliance body 10 and a root control attachment 20, wherein the invisible orthodontic appliance body 10 is formed by cutting a transparent polymer material positive pressure on a 3D printed tooth model and is used for being worn on teeth;
