Firstly, digital design enables the precise acquisition of patients' oral data. Using high-precision oral scanners or CBCT equipment, three-dimensional image data of the patient's mouth can be obtained. These data include detailed information about the shape, size, and position of teeth, as well as the periodontal tissues. Compared to traditional manual measurement and impression techniques, digital scanning is faster, more accurate, and avoids the discomfort potentially caused by impression materials.
