Abstract
Description
technical field
[0001] The invention belongs to the field of medical detection and medical equipment, and relates to an oral cavity scanning device and method. Background technique
[0002] In the current clinical practice of stomatology, the methods of obtaining dental conditions mainly rely on making dental models, optical examinations and X-ray examinations. The dental model can visually see the condition of all the crowns, but the production is relatively time-consuming, has many steps, and will be affected by the oral environment. X-rays can diagnose some problems that are not noticeable in appearance, and can accurately see whether there is any abnormality in the condition of teeth.
