Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Examples

As shown in fig. 1, 2 and 3, a device for invisible tooth correction comprises a device main body 10, wherein the device main body 10 comprises a plurality of retention cavities 20 and correction cavities 30 which are sequentially spliced, each retention cavity 20 comprises two oppositely arranged support surfaces 21, each correction cavity 30 comprises a correction surface 31 and an accommodation surface 32 which are oppositely arranged, one support surface 21 of each retention cavity 20 and the correction surface 31 of each correction cavity 30 are positioned on the same side of the device main body 10, top surfaces 22 are respectively connected between the tops of the two support surfaces 21 of each retention cavity 20 and between the correction surface 31 and the accommodation surface 32 of each correction cavity 30, clamping grooves 40 are respectively arranged on the inner sides of the end parts of the two support surfaces 21 of each retention cavity 20 and the correction surfaces 31 and the accommodation surfaces 32 of each retention cavity 30 facing the same direction, clamping grooves 41 matched with the clamping grooves 40 are respectively arranged on the inner sides of the end parts of the two support surfaces 21 of each retention cavity 20 and the correction surfaces 31 and the accommodation surfaces 32 of each retention cavity 30 facing the other direction, the clamping grooves 40 and the clamping protrusions 41 are arranged along the opening direction from the corresponding top surface 22 to the corresponding retention cavity 20 or correction cavity 30; the inner side of the correcting surface 31 is provided with a correcting accessory 50.

The retention cavity 20 and the correction cavity 30 are both made of a transparent polymer material with biocompatibility, wherein the retention cavity 20 corresponds to teeth which do not need to be treated with george, and the correction cavity 30 corresponds to teeth which need to be corrected for movement. The retention chamber 20 and the correction chamber 30 can be formed in a shape designed to fit the oral cavity and the malformed dentition of the patient. After each retention cavity 20 and the correction cavity 30 are manufactured separately, the corresponding clamping groove 40 and the corresponding clamping protrusion 41 are processed, and then the whole appliance main body 10 is assembled through the installation of the clamping groove 40 and the clamping protrusion 41.

The orthodontic attachment 50 is mainly used for correcting misaligned teeth, and can accelerate the orthodontic period.

After wearing the appliance for a period of time, along with the movement of the unevenly arranged teeth, the appliance 50 in the correction cavity 30 may have the condition that the correction cannot be continued, at the moment, the cavity 30 can be made and corrected for the teeth again, and the whole appliance main body 10 cannot be replaced, so that the correction cost is greatly saved.

In one embodiment, the locking protrusion 41 has a triangular structure with a high middle and two low ends, and the locking groove 40 is matched with the locking protrusion 41 in shape.

The clamping protrusions 41 which are high in the middle and low in the two ends are triangular, and are not easy to move after being clamped into the clamping grooves 40.

In one embodiment, the orthodontic attachment 50 is an orthodontic protrusion in the shape of a prism.

The prismoid-shaped inclined surface can guide the teeth into the orthodontic cavity 30, and damage to the teeth is avoided.

In one embodiment, the orthodontic attachment 50 is detachably connected to the orthodontic surface 31.

The correction accessory 50 can be adhered to the inner side of the correction surface 31 by using biocompatible glue, and when the correction cavity 30 needs to be replaced, only the correction accessory 50 can be replaced, so that the correction cost is further saved. Of course, the correction accessory 50 can also be connected to the correction surface 31 by other methods, for example, a slide block is connected to a slide rail arranged on the correction surface 31, and the depth of the slide rail is gradually reduced from top to bottom, so that the correction accessory 50 can be prevented from falling off during normal use.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
