Embodiment example 1
[0052] like figure 1 , figure 2 , image 3 and Figure 4 As shown, the present invention provides a technical solution: a digital diagnosis method for skeletal Class III malocclusion based on biomechanics, comprising the following steps:
[0053] S1. Cephalometric measurement and preliminary diagnosis: determine the skeletal class III malocclusion, and measure the patient's ANB angle;
[0054] S2. Select a case and scan it: directly scan the patient's upper and lower dentition data through an intraoral scanner, and obtain the patient's jawbone and dentition data through CT scanning;
[0055] S3. 3D modeling: Input the patient's upper and lower dentition data and the patient's jaw and dentition data obtained in step S2 into the medical image processing and modeling software, and fuse the common dentition data to construct a complete tooth structure. 3D models of columns and jaws;
[0056] S4. Determine the treatment direction and perform virtual treatment: According to the ...

Abstract
The invention discloses a biomechanics-based digital diagnosis method and system for bony class III malocclusion, and relates to the technical field of medical technologies and instruments, in particular to a biomechanics-based digital diagnosis method and system for bony class III malocclusion, comprising the following steps: S1, head shadow measurement and preliminary diagnosis; s2, selecting and scanning a case; s3, carrying out three-dimensional modeling; s4, judging a treatment direction, and performing virtual treatment; and S5, treating the patient according to the analysis. Through biomechanical analysis on the temporomandibular joint in the treatment process of a bony class III malocclusion patient, the problems of condylar process absorption, joint disc displacement and perforation caused by overlarge pressure and shearing force during mandibular movement are effectively avoided; the invention also provides a novel digital diagnosis method for osteogenic III-type malocclusion in combination with head shadow measurement parameters and biomechanics.
Description
technical field [0001] The invention relates to the technical field of medical technology and equipment, in particular to a digital diagnosis method and system for skeletal class III malocclusion based on biomechanics. Background technique [0002] Skeletal Class III malocclusion is a relatively common clinical malocclusion, which is characterized by overdevelopment of the mandible, underdevelopment of the maxilla, or both. Lower front teeth and tongue tilt etc. [0003] There are currently three main approaches to the treatment of skeletal Class III malocclusions, namely growth control, orthodontic compensation, and orthognathic surgery. Growth control should be carried out before the rapid puberty period. After the rapid puberty period, only the latter two methods can be used to treat adult skeletal class III malocclusion. At this time, it is a difficult problem for clinicians to decide the treatment plan of patients. Skeletal class III malocclusion is mainly due to the ...
