Does the dental tablet machine have a ballast?

No, the dental tablet machine usually consists of an X-ray generator and its supporting components, which are used in conjunction with the intraoral image receiver. It is used for X-ray photography of teeth to obtain images for clinical diagnosis. It's simpler. Generally, two-dimensional images of 1 to 4 teeth can be taken at the same time, but the structure overlap is serious and the range is small.
