2. TMJ evaluation: evaluate the proportion of three joint cavity around the condyle, condylar morphology, whether there is absorption, abrasion, and even trauma. Condylar fracture 3.Guide the planting of the implant nails, choose the implant site, the height and angle, to ensure the implant security and stability. Planting the nail between roots While CBCT technology is of tremendous value in clinical medicine, it’s important to remember these scans still expose our patients to radiation and therefore should only be used when indicated and not simply in cases for which there is not a need or indication. At the beginning of this lesson, we will learn about CBCT, and some of the clinical application. Cbct is short for the Cone beam computed tomography,it is a kind of 3D imaging system, it offers complete treatment solutions for the GPs, oral surgeons, orthodontists, and other specialists . CBCT system contains three parts, first, , The three dimensional reconstruction The actual CBCT scan takes approximately 20 seconds.? The total appointment time (including registration, positioning, scanning, reconstruction, and scan verification) is less than one hour. The main differences between CBCT and medical (multi-slice) CT are * CBCT offers complete treatment solutions for the GPs, oral surgeons, orthodontists, and other specialists . * We use CBCT to to analyze the weight of bone and provide more accurate information related to size, extent, location, and the relation to and effect on nearby anatomical structures. . * Consequently it is possible to design treatment strategies that would result in less invasive surgical intervention to analyze the weight of bone and provide more accurate information related to size, extent, location, and the relation to and effect on nearby anatomical structures. . * 3d补充不能取代2d * The patient had presented with biting sensitivity after the crown had been placed some months later.The regular 2D x-ray image showing n
