Abstract

The invention discloses an invisible appliance with controllable thicknesses in all directions and a preparation method thereof. The method comprises the following steps of preparing appliance films with different thicknesses; placing the appliance films with different thicknesses on a dental cast; and adjusting the position and the direction of the dental cast as required, and carrying out hot press molding to obtain the required invisible appliance. By means of the method, it can be set that the tooth tip part of the invisible appliance is relatively thick, the position needing relatively large correction force is relatively thick, and the part which does not need correction is relatively thin, so that the thicknesses of the invisible appliance in all directions can be adjusted accordingto an actual correction scheme, control over correction force in all directions is achieved, and therefore the correction curative effect is improved, the correction period is shortened, and moreover, the correction experience of the patient is improved, and personalized correction is truly realized.

Description

technical field

[0001] The invention relates to the technical field of preparation of invisible aligners, in particular to an invisible aligner with controllable thickness in all directions and a preparation method thereof. Background technique

[0002] At present, the treatment methods of orthodontics mainly include traditional brackets and invisible appliances. Invisible appliances do not have the wires and brackets in the traditional orthodontic process, and they do not affect the appearance and other outstanding advantages, so they are widely favored by estheticians.

[0003] Although the existing invisible aligners have the advantages of beautiful appearance, precise positioning, and convenient cleaning compared with traditional bracket aligners, due to the current manufacturing process of invisible aligners, the existing invisible aligners are heated through the aligner film and dental mold. According to the characteristics of the hot pressing forming process, the cent...
