The attachments (i.e., invisible orthodontic attachments) are specially designed, made of dental resin, are attached to the tooth surface by means of an attachment positioning guide (also called an attachment guide, or an attachment template, usually the first appliance) and are auxiliary devices for controlling tooth movement and enhancing retention in invisible correction, can control the corrective force transmitted to the teeth and the manner of tooth movement, assist in achieving some predictability of tooth movement, and are part of the invisible orthodontic mechanical system.

The existing invisible orthodontic accessory positioning guide plate (accessory guide plate) is generally an integral membrane plate which is made of transparent soft plastic and provided with tooth sockets which are inwards concave, a single accessory guide plate is similar to an inwards concave tooth socket, and the inner wall of the inwards concave part of the tooth socket is provided with a concave area (namely an accessory cavity) which can be filled with accessories. After the accessory guide plate is worn in an arch, the bottom of the concave part of the tooth socket of the single accessory guide plate can be matched with the occlusal surface of the tooth, and the concave area on the inner wall of the concave part of the tooth socket, namely the accessory filled in the accessory cavity, can be attached to the tooth surface. When the existing accessory guide plate is adopted to carry out accessory bonding operation, the concave area of the accessory positioning guide plate, namely the accessory cavity, is filled with dental resin and then is covered on teeth for pressing, so that the redundant dental resin overflows, but the overflowing resin can form a thin resin layer around the accessories on the surfaces of the teeth, and therefore the accessories and the accessories in the design scheme have deviation, the corrective force which is required to be transmitted to the teeth by the accessories in the corrective process is influenced, and the corrective time and the corrective effect are prolonged.

the specific situation is as follows: in the invisible orthodontic treatment of teeth, a concave area (namely an accessory cavity) capable of being filled with accessories is arranged on the inner wall of the concave part of the accessory guide plate tooth socket, and the shape and the size of the concave area (the accessory cavity) correspond to those of the accessories designed in computer software. The method for manufacturing the attachment by adhering comprises the steps that a doctor or an operator fills dental resin (the resin can be flowable resin, medium-hardness resin or high-hardness resin) in a concave area (an attachment cavity) of an attachment guide plate, after the dental resin is filled, the doctor or the operator covers the attachment guide plate with the dental resin on the surface of a tooth, and as a tooth socket model of the attachment guide plate is usually about 0.3-0.5mm and is very thin, the dental resin is tilted in the covering process, if the attachment is directly fixed by resin illumination, the attachment is heightened, so that the concave area of the attachment guide plate needs to be pressed by a tool, the attachment guide plate is tightly attached to the tooth surface, and redundant dental resin overflows. Because the accessory guide plate is a whole (only one tooth socket is provided), the whole tooth socket is completely sleeved on the whole tooth, the whole tooth socket covers the whole tooth surface, and because the fluidity of the resin is not good, in the overflowing process, the redundant dental resin can only overflow to the tooth surface and can not overflow to the gum for removal, the resin overflowing to the tooth surface is covered by the tooth socket, and the overflowing redundant resin is difficult to remove by a tool, so that a thin resin layer is formed around the accessory. The result of this operation is that the attachments adhered to the tooth surface are not identical to the attachments of the design, so that the attachments are deviated from the attachments of the design, the corrective force which should be transmitted to the teeth by the attachments in the process of correction is influenced, and the correction time and the corrective effect are prolonged.

In addition, the existing accessory guide plate is a whole dental model accessory guide plate, if a certain accessory falls off in the straightening process, the original accessory guide plate cannot be reused, because the whole dental model accessory guide plate is made of a soft membrane (plastic membrane) with the thickness of about 0.3-0.5mm, and the adhesion of a single dental accessory by cutting off one part of the soft membrane cannot be realized, because teeth are moved in the straightening process, the accuracy of the accessory position cannot be ensured.
