Abstract: The present invention relates to the technical field of dental medical treatment, and specifically discloses a method for using a CBCT (Cone Beam Computer Tomography) for automatically positioning a tooth, which comprises the following steps: S01, archiving CT data; S02, calculating AI and generating AI results; S03, entering CT reading by a client; S04, downloading and loading the CT data; S05, opening a function of a tooth lens; S06, selecting a corresponding tooth position in a tooth position list; and S07, selecting a 3D tooth rendering mode. The function of the ‘tooth lens’ is added into traditional CT reading, which is suitable for clinical disease diagnoses such as ‘tooth extraction, root canal therapy, tooth repair’ and the like in oral treatment, and doctors can precisely and quickly position the single tooth through selection for the tooth position, which facilitates more comprehensive analysis.

Abstract: A method for visible cephalometric measurement is provided. The method comprises: acquiring a data item to be measured according to a preset analysis method, and acquiring preset reference information; determining a measurement reference point according to the acquired preset reference information; and generating a measurement result based on the measurement reference point and the data item to be measured, and displaying it. A computer processing device and a visible cephalometric system are also provided. The computer may automatically generate measurement results according to user's selection and perform cephalometric measurement more easily, accurately, and more efficiently.

Abstract: The present disclosure discloses a method for drawing a cranial image trajectory. The method comprises: providing, by a processor, at least one trajectory pattern template for parts of a standard cranial anatomy; acquiring, by a radiation image device, at least one cranial image of a patient, superimposing, by the processor, the trajectory pattern template of each part of the standard cranial anatomy onto the corresponding position of the patient's cranial image, and acquiring the trajectory pattern of the cranial image; and if a deviation is determined between the shape of the respective structure on the trajectory pattern of the patient's cranial image and that of the trajectory pattern template of each part of the standard cranial anatomy, adjusting the shape of the corresponding trajectory pattern template in the cranial anatomy so as to be the same as the respective structure in the cranial image by the processor.
