The gingival lateral edge 122 protrudes beyond the lateral edge of the adhesive surface 110 to form a second locating edge 1221, and the transparent invisible appliance 300 is provided with a second wrapping edge 303 that mates with the second locating edge 1221. The transparent invisible appliance 300 is also provided with a beveled guide edge 304 on the side away from the first wrapping edge 302, and the beveled guide edge 304 is used for driving the transparent invisible appliance 300 to deform so as to wrap the aesthetic fixed appliance by itself. The transparent invisible appliance 300 is provided with reinforcing ribs 305 arranged in an array at the part closing the archwire slot 200. The provision of the reinforcing ribs 305 can avoid the problem of the reduction in the restraining capability of the dental arch wire due to the side opening.

Referring to fig. 25 to 28, the present application further discloses an aesthetic fixation appliance, which is characterized in that the body 100 of the aesthetic fixation appliance has a double-layer structure compared to other embodiments, wherein the volume of the lower portion for forming the bonding surface is larger than the volume of the upper portion for forming the arc-shaped mating surface, and the upper portion and the lower portion can be provided with a stop plane 140 for limiting. In the embodiment shown in the drawings, the archwire slot 200 is positioned at the upper part, and at least a part of the archwire 500 passes through the archwire slot 200 and passes through the upper part of the lower part; the transparent invisible appliance 300 covers the upper portion and a portion covers the upper surface of the lower portion. The specific arrangement of the upper portion may be as described with reference to the aesthetic fixation appliance of figures 5 to 8 b.

Between the examples, the schemes are each emphasized.

Compared with the first embodiment, the aesthetic fixing appliance in the second embodiment is mainly characterized in that the cleaning groove 201 is formed, so that the aesthetic fixing appliance is convenient to clean in the treatment process.

The aesthetic fastening appliance of the third embodiment differs from the first and second embodiments primarily in that the archwire slot 200 is open to the arcuate mating surfaces 120.

Compared with the third embodiment, the aesthetic fixed appliance in the fourth embodiment is mainly distinguished by the arrangement of the constraint structure, so that the bonding strength between the transparent invisible appliance 300 and the body 100 is improved.
