Description

Retention device with intraoral photographing device

Technical Field

The application relates to the technical field of oral medical treatment, in particular to a retainer with an intraoral photographing device.

Background

Generally, after the orthodontic treatment is finished, a dentist needs to extend a dental mirror into the oral cavity to observe the condition of teeth in the mouth, and the mouth of a patient needs to be opened in the whole observation process, so that the mode can only observe the specific tooth condition, but cannot observe the occlusion condition of the upper and lower teeth from the tongue and jaw side.

In the intraoral photography method, only the occlusion of teeth on the labial and buccal sides in the oral cavity can be photographed, but the occlusion of teeth on the lingual and mandibular sides cannot be photographed, and therefore the evaluation of the orthodontic effect after the completion of the correction often involves only the labial and buccal states, and the evaluation result is not comprehensive.

At present, the occlusion condition of the lingual and palatal side teeth can be observed by acquiring the information of the upper and lower jaw dentition through a tooth model or intraoral scanning and the like and matching with an extraoral re-occlusion mode, but the operation steps are complicated, the operation is a secondary operation which is time-consuming and needs secondary manpower and material resources, the occlusion of the entity without directly seeing the teeth is more visual, and the confidence is stronger.

Therefore, a device for acquiring the occlusion condition of the lingual tooth and the palatal tooth directly from the oral cavity is needed.
