Embodiment 1

[0042]A method for preparing a lingual orthodontic device for orthodontics, the method comprising the following steps:

[0043]S1: Establishment of a digital tooth model: use an intraoral scanner to scan the tooth to obtain a digital tooth model;

[0044]S2: Determination of the shape of each bottom plate 1: First, import the digital tooth model into the dental model analysis software, and then intercept the contour of each bottom plate 1 on the lingual surface of each tooth, so that each bottom plate 1 matches the surface of the tooth On the lingual surface of the corresponding tooth, and the area of ​​each bottom plate 1 is two-thirds of the lingual area of ​​the tooth to which it is attached, and the thickness is both 0.3mm; at the same time, the mesial and distal ends of each bottom plate 1 The ends are correspondingly extended into the abduction gap of the tooth; then two first overflow holes are designed along the mesio-distal direction on each bottom plate 1, and two second overflo...

Embodiment 2

[0052]A method for preparing a lingual orthodontic device for orthodontics, the method comprising the following steps:

[0053]S1: Establishment of a digital tooth model: use an intraoral scanner to scan the tooth to obtain a digital tooth model;

[0054]S2: Determine the shape of each bottom plate 1: first import the digital tooth model into the dental model analysis software, and then intercept the contour of each bottom plate 1 on the lingual surface of each tooth, so that each bottom plate 1 is consistent with the fitting surface of the tooth On the lingual surface of the corresponding tooth, and the area of ​​each bottom plate 1 is two-thirds of the lingual area of ​​the tooth to which it fits, and the thickness is 0.7mm; at the same time, the mesial and distal ends of each bottom plate 1 The ends are correspondingly extended into the abduction gap of the tooth; then two first overflow holes are designed along the mesio-distal direction on each bottom plate 1, and two second overflow...

Embodiment 3

[0061]A method for preparing a lingual orthodontic device for orthodontics, the method comprising the following steps:

[0062]S1: Establishment of a digital tooth model: use a dental 3D scanner to scan a tooth model made of dental plaster or silicone rubber to obtain a digital tooth model;

[0063]S2: Determination of the shape of each bottom plate 1: First, import the digital tooth model into the dental model analysis software, and then intercept the contour of each bottom plate 1 on the lingual surface of each tooth, so that each bottom plate 1 matches the surface of the tooth On the lingual surface of the corresponding tooth, and the area of ​​each bottom plate 1 is two-thirds of the lingual area of ​​the tooth to which it is attached, and the thickness is both 1.0mm; at the same time, the mesial and distal ends of each bottom plate 1 The ends are correspondingly extended into the abduction gap of the tooth; then two first overflow holes are designed along the mesio-distal direction o...

Abstract

The invention particularly relates to a preparation method of a lingual orthodontic device for tooth correction, and solves the problems that an existing lingual orthodontic technology is difficult toinstall in application, and orthodontic wire correction force cannot be kept consistent all the time. The preparation method of the lingual orthodontic device for tooth correction comprises the following steps of S1, establishing a digital tooth model; S2, determining the shape of each bottom plate; S3, determining the shape of an orthodontic band-shaped body; S4, preparing the orthodontic band-shaped body; S5, preparing the bottom plates; and S6, assembling the orthodontic band-shaped body and the bottom plates. According to the method, the purposes of easy installation and light correctionare realized, the pain in the tooth correction process is effectively reduced, the tooth movement efficiency is improved, the operation amount of doctors is reduced, meanwhile, the wearing comfort ofpatients is improved, the lingual orthodontic technical level is effectively improved, and the method has positive popularization significance.

Description

Technical field[0001]The invention relates to a preparation method of an orthodontic device for medical equipment, in particular to a preparation method of a lingual orthodontic device for tooth correction.Background technique[0002]In the field of orthodontics, labial orthodontics, lingual orthodontics, and bracketless invisible orthodontics are three commonly used orthodontic methods. Among them, the labial orthodontic technique requires fixing orthodontic devices such as "wire iron teeth" on the labial surface of the teeth, resulting in poor aesthetics; bracketless invisible orthodontic technology is still affecting the overall movement and elongation of the teeth. , Depression and rotation are difficult to control, and applicable cases have their limitations. The lingual orthodontic technique can overcome the deficiencies of the above two techniques. It has stronger control over the overall movement of the teeth, as well as the elongation, depression and rotation of the teeth. Th...
