Problems solved by technology

This is a universal appliance (common for different patients), which is directly placed on the corresponding teeth by the orthodontist using adhesives in clinical practice. It has the advantages of simple clinical operation, precise control of tooth movement, ideal treatment effect and low price. Advantages such as economy; the biggest disadvantage is that the appliance is located on the lip and buccal surface of the teeth, which is easily exposed to the outside, thus affecting the appearance
[0005] It can be seen that the tooth adjustment steps in the prior art are cumbersome and inconvenient for actual production operations. Therefore, it is necessary to provide a method for designing an orthodontic treatment plan

Embodiment 1

[0032] The invention discloses a method for designing an orthodontic treatment scheme, comprising the following steps:

[0033] S1. Analyze oral panorama films and oral lateral views by means of interactive manual annotation or automatic data recognition to obtain the position of each tooth in the film, calculate the tooth direction information, and obtain the tooth crown direction information and Root position information; if it is a standard DICOM digital image, the specific coordinate information of each tooth can be obtained; the 3D digital model of the jaw can be obtained through an intraoral scanner;

[0034] S2. Obtain the coordinate system of the 3D digital model of the dental jaw through the minimum bounding box algorithm and point cloud data distribution, cut the dental model by manual cutting or other automatic cutting methods, obtain the 3D digital model of the crown, and compare it with the obtained teeth The crown direction information and tooth root position inf...

Embodiment 2

[0057] The invention discloses a method for designing an orthodontic treatment scheme, comprising the following steps:

[0058] S1. The tooth image is obtained by scanning the tooth with CT equipment, and the direction information of the tooth crown and the position information of the tooth root are obtained through three-dimensional reconstruction; after the reconstruction, the crown and root information cannot be separated, but the tooth tooth can be calibrated in the software through an interactive method Crown direction information and tooth root position information; the plaster model of the jaw is obtained from the tooth impression, and the plaster model of the tooth is scanned by a special dental 3D scanning device to obtain a three-dimensional digital model of the jaw.

[0059] S2. Obtain the coordinate system of the 3D digital model of the dental jaw through the minimum bounding box algorithm and point cloud data distribution, cut the dental model by manual cutting or ...

Embodiment 3

[0081] The invention discloses a method for designing an orthodontic treatment scheme, comprising the following steps:

[0082] S1. The tooth image is obtained by scanning the tooth with CBCT equipment, and the crown direction information and tooth root position information are obtained through three-dimensional reconstruction; the crown and root information cannot be separated after reconstruction, but the tooth tooth can be calibrated in the software through an interactive method crown direction information and tooth root position information; obtain a plaster model of the jaw for the tooth impression, and then dye each tooth of the plaster model, and dye each tooth a different color, and the dyed color is consistent with the teeth and gums The natural colors of the teeth are different, different colors are used to distinguish the teeth from the gums, and to distinguish a single tooth; obtain the 3D digital model of the crown and the 3D digital model of the whole jaw at one t...

Abstract

The invention discloses a method of designing an orthodontic correction scheme. Based on a tooth-jaw three dimensional digital model, the digital model is analyzed, the deformity degree is judged, orthodontic correction suggestion is obtained, and an orthodontic correction scheme is automatically designed. Through the intelligent design, the design efficiency and effectiveness of the orthodontic correction scheme are both improved.

Description

technical field [0001] The invention relates to the field of orthodontics, in particular to a method for designing an orthodontic treatment scheme. Background technique [0002] At present, the orthodontic appliances used to correct misaligned teeth are mainly labial fixed appliances, which are usually made of metal brackets / buccal tubes bonded to the labial surface of the teeth (buccal tubes are generally used for molars), and each bracket is connected in series. The arch wire and ligature wire of the groove / buccal tube are composed of the elastic arch wire to align the dislocated teeth, and the thick stainless steel wire with high hardness is used as the stable wire to close the tooth extraction gap. This is a universal appliance (common for different patients), which is directly placed on the corresponding teeth by the orthodontist using adhesives in clinical practice. It has the advantages of simple clinical operation, precise control of tooth movement, ideal treatment e...
