Description

Auxiliary devices for dental procedures {AUXILIARY APPARATUS FOR DENTAL TREATMENT}

The present disclosure relates to an auxiliary device for a dental procedure, and more particularly, to an auxiliary device for a dental procedure that can secure a treatment field by pushing or pulling a patient's soft tissue in a specific direction while inhaling a by-product in the oral cavity. it's about

In general, during dental treatment, foreign substances such as water, saliva, blood, etc. continue to accumulate in the oral cavity of a patient while the treatment is in progress. When these foreign substances stay in the oral cavity, the working field of view of the treatment area is not secured, and the probability of viral infection or bacterial disease occurring in the treatment area increases. Therefore, it is essential to remove foreign substances generated during dental procedures using suction. In addition, in order to secure a working field of view for a treatment area during dental treatment, a retraction operation is required to push or pull the patient's soft tissues, such as the tongue and cheek, in a specific direction through a retractor.

That is, during dental treatment, for smooth treatment, it is necessary to push or pull the soft tissue of the patient through a retractor operation to secure a working field of view of the treatment area and to suck foreign substances through a suction operation. However, in order to perform the retractor work and the suction work at the same time, it is difficult to proceed with the treatment alone without the help of a dental hygienist, and the retractor work and the suction work are only auxiliary tasks, so there is a problem that the worker's will to work is lowered. .

On the other hand, when a tooth is removed to treat a treatment site, fine dust may be generated. In this case, there is a problem that a working field of view for the treatment site may not be secured due to the fine dust, and viral infection or bacterial disease may occur at the treatment site.
