Description

Tooth imaging device

Technical Field

The utility model relates to a medical diagnostic equipment, especially a tooth imaging device.

Background

In the existing dental imaging technology, two methods are generally adopted to obtain images:

one is to display information about the interior of the tooth using X-ray imaging, including cavities and pores in the tooth tissue. X-ray imaging is effective because cavitated and demineralized areas are more transparent to X-rays than surrounding tissue and therefore transmit higher intensity X-rays emanating from the wash-out, resulting in a stronger exposure on photographic film or on an electronic imaging device than with radiation coming along a nearby path that does not intersect the cavitated or demineralized areas. However, X-ray imaging also has the disadvantage that X-rays ionize molecules in living tissue and are harmful to the human body.

The other method is to take a picture of the tooth, namely, a sensing camera is used for taking the picture. In the process of taking a picture, the mouth is pulled open by the mouth corner pull hook to take a picture, and a patient can take a proper picture only by matching the mouth corner pull hook with the mouth corner pull hook. When a picture of the top surface of the dental crown is taken, the oral cavity is pulled open by pulling the hook, a mirror is required to be placed in the oral cavity for reflecting the dental bottom, and another medical staff is required to blow the mirror to prevent the mirror from fogging, so that the picture can be taken. The photo of the lingual surface of the tooth is the same as the photo of the crown top surface, and the photo can be taken by a plurality of persons. It is very inconvenient to use.
