Description
Technical field
The present invention relates to the arch wire fields of orthodontic, and in particular to a kind of digitlization arch wire selection method and its device.
Background technique
Malocclusion is a kind of common multiple mouth disease.Malocclusion is to oral health, oral cavity function, jaw face
The development of skull and appearance all have a great impact.Mouth cavity orthodontic is that one in oral health treatment is essential important
Component part.Arch wire is common device during orthodontic, assigns arch wire and bending specific arch specifically to count
According to, and pass through the size of the thickness of arch wire embodiment Orthodontic force.Arch wire is placed in orthodontic appliance, and then the data of arch wire are assigned
Give tooth, arch wire and tooth mutually exert on that active force makes that denture arranges more neatly with beauty.The size of arch wire with
The arch of arch wire is the highly important data of arch wire, influences the effect of orthodontic.
It is highly important that the arch wire of a suitable patient is selected during orthodontic, but due to each patient mouthful
The difference of chamber environment, orthodontist tends not to the arch wire for selecting to be most suitable for patient, to influence the effect of orthodontic treatment.It is existing
There are two ways to selecting arch wire: it is a kind of to select arch wire by the experience of oneself for doctor, but such method is easy because of ring
The difference in border and the deficiencies of doctors experience and generate great error；Another kind is digitized to pass through rambling denture
Row's tooth method lines up ideal denture, retrodicts the data of arch wire by ideal denture later, but the arch wire of such method acquisition
Often it must can realize that inefficiency is with high costs, cannot be extensive by personalized designs and customization for ideal wire

The upper jaw arranges tooth curve and the upper jaw arranges teeth plane, calculates the maxillary teeth in the denture threedimensional model through fitting optimization and is moved to
Translational movement and rotation amount needed for upper jaw target tooth position, mobile maxillary teeth to upper jaw target tooth position, generate target
Maxillary dentition；
Teeth plane is arranged based on lower jaw target arch wire building lower jaw row's tooth curve and lower jaw, calculates the tooth through fitting optimization
Translational movement and rotation amount needed for mandibular teeth in column threedimensional model is moved to lower jaw target tooth position, mobile mandibular teeth
To lower jaw target tooth position, target mandibular dentition is generated.
9. digitlization arch wire selection method as claimed in claim 7 or 8, which is characterized in that row's teeth plane includes center
Sagittal plane, horizontal plane and row's facies occlusalis dentis；Row's tooth curve includes corona midpoint row's tooth curve；The target tooth position
Including denture sagittal to position, denture vertically to position between position and tooth.
10. digitizing arch wire selection device characterized by comprising
Import modul, the denture threedimensional model that scanning is obtained import computer；
Module is obtained, according to the denture obtaining three-dimensional model denture variable；The denture variable includes: A, B, C, D, E, F；Its
Middle A is with jaw side midline shift amount, and B is to deviate normal value with jaw side incisor torque angle 1-SN, and C is with jaw side two sides canine tooth tooth
Sharp wire length, D are with jaw side two sides first molar central fovea wire length, and E is with jaw side central incisor intermediate point to same jaw side
The perpendicular bisector length of two sides first molar central fovea line, F are to deviate standard value difference with the full tooth section of jaw side Bolton；
Computing module calculates arch wire approach based on the denture variable, and expression formula is as follows:
X=(a-A) A+ (b-B) B+ (d-D) * squ (E2+(D/2)2)+(c-C)C-F
Wherein, X is arch wire approach, and a is the laminating mean value of tooth, and b is root of the tooth gradient mean value, and c is with jaw side two sides canine tooth tooth
Sharp wire length mean value, d are with jaw side two sides first molar central fovea wire length mean value；
Matching module matches corresponding target arch wire according to the arch wire approach from arch wire database.
