Embodiment Construction
[0023] S1: Desensitize the acquired CBCT data, if there is preoperative and postoperative data of the same case, it will be matched automatically
[0024] S2: Extract the two-dimensional image data stored in the database, and perform manual punctuation processing on the interface according to the anatomical structure of the hard tissue of the tooth. Import the CBCT image in DICOM format into the software, and mark the hard tissue with selected feature marker points in the coronal, sagittal, and horizontal plane images by manual labeling.
[0025] S3: According to the results of manual punctuation, the system automatically generates a three-dimensional digital dental model and automatically marks important anatomical structures. Through preprocessing, it is confirmed that the information of the input case characteristics has been quantified; the unquantified information will be quantified through the coding program for input. Input the quantified feature data The quantified fe...

The invention relates to an orthodontic operation scheme interactive simulation and evaluation system based on artificial intelligence, belongs to a full-operation-period interactive simulation and evaluation platform, and solves the problems that existing operation is difficult to obtain visual expected operation results, visual hard tissue change degree and the like. According to the invention,a traditional radiographic imaging technology, a virtual reality technology and artificial intelligence analysis are creatively combined, a doctor performs virtual surgery operation and design througha constructed three-dimensional model and tracks image changes in the surgery process, and the doctor can perform virtual surgery operation and design through a corresponding algorithm of a self-interactive surgery simulation platform; a series of changes of the hard tissue are mapped according to the operation of a doctor, then the hard tissue is covered with the soft tissue, and finally an intuitive predicted operation result is obtained. The medical record difficulty, the operation scheme score and the actual operation effect score are scored by means of an expert decision-making system, the scheme of a doctor is modified through the virtual operation effect, the controllability and effect of an operation are greatly improved, and the method can be used for clinical and scientific research analysis.
Description
technical field [0001] The invention belongs to the field of artificial intelligence, and relates to an interactive simulation and evaluation system for orthodontic surgery based on artificial intelligence and virtual reality. Background technique [0002] The design of a treatment plan with a high level of oral aesthetics currently relies heavily on the doctor's rich clinical work experience, which mainly depends on the doctor's own understanding of malocclusion and the reserve of biomechanical knowledge. For example, because there are many unreliable factors in orthodontics, and the current professional level of orthodontists is quite different, there are cases where the results of orthodontic surgery vary greatly. The original tooth arrangement experiment was performed on a plaster model, which helped doctors predict the treatment outcome to a certain extent. However, this method inevitably destroys the adjacent points of the teeth in the process of dividing the teeth, s...
