Description

technical field [0001] The invention relates to the technical field of medical aids, in particular to a dental CT mandibular positioning device. Background technique [0002] Modern people do not pay attention to the maintenance of oral hygiene in daily life, and they are prone to common problems such as dental caries, tartar, dental plaque, bleeding gums, dentin sensitivity, unclean teeth and bad breath. If these problems are paid attention to, they are likely to cause cardiovascular diseases and diabetes etc. With the improvement of the quality of life, everyone's awareness of protection has increased, and they are constantly paying attention to the protection of teeth, and do oral CT regularly. Oral CT can reflect the tissue situation from a three-dimensional perspective, and can find subtle lesions that cannot be found in the projection angle of oral X-ray films; its three-dimensional reconstruction effect can accurately evaluate the bone tissue and mandibular joint con...

Problems solved by technology

[0003] At present, when patients use dental CT detection and imaging, the mandible needs to be positioned. When the mandible is positioned, it needs to be adjusted continuously according to the patient's head shape to ensure a good tightening and fixing effect. Such positioning operation is extremely inconvenient and easily causes the patient to be nervous.
