Embodiment 1
[0045] Such as figure 1 with figure 2 As shown, a dental surgery real-time assistance system based on augmented reality three-dimensional imaging includes: a medical imaging system, a motion capture system, a data processing system and an AR display system; the data processing system includes: a three-dimensional reconstruction module, an operation planning module, Match positioning module and motion tracking module;
[0046] The medical imaging system collects surgical requirements and 3D medical imaging data of patients, and sends them to the data processing system;
[0047] The three-dimensional reconstruction module performs three-dimensional reconstruction on various tissues of the surgical site based on the surgical requirements and the patient's three-dimensional medical image data to obtain a three-dimensional virtual image, and the three-dimensional reconstruction device sends the three-dimensional virtual image to the operation planning module;
[0048] The operat...
Embodiment 2
[0071] This example takes the most common oral implant surgery in dentistry as an example to illustrate the oral implant surgery assisted by AR augmented reality real-time 3D imaging:
[0072] Take the CBCT of the patient, perform three-dimensional reconstruction of the teeth, alveolar bone, inferior alveolar canal, and maxillary sinus cavity in the CBCT, and perform different renderings of different tissues;
[0073] The surgery planning module uses 3shape Implant Studio to carry out implant surgery planning simulation, select the finished 3D model of the dental implant in the database, and put it into the 3D reconstruction of the alveolar bone at a suitable position, angle, and depth. Open the adjacent teeth and nerve canal to achieve the most ideal implant site. Then the 3D reconstructed model and the implant model of implant surgery planning are rendered in different colors and exported to a common 3D format .obj file.
[0074] Fix the scanning motion capture system so th...
Embodiment 3
[0082] This example uses the most complex orthognathic surgery in dentistry to illustrate the orthognathic surgery assisted by AR augmented reality real-time 3D imaging.
[0083] Take the CBCT of the patient, perform three-dimensional reconstruction of the teeth, alveolar bone, inferior alveolar canal, and maxillary sinus cavity in the CBCT, and perform differential rendering of different tissues;
[0084] Orthognathic surgery planning: use the industrial 3D modeling software Materialize Magics for surgical planning, first arrange the relative positions of the dentition to achieve the clinical ideal occlusal state, and meet the better side aesthetic standards, and then compare the front and rear alignment jaws, Avoid important blood vessels and nerves, find the ideal osteotomy plane, use the cutting tool to cut and move the front jaw to the position of the aligned dentition, and then make the 3D reconstruction model and the implant model of the implant surgery plan different co...
