Description

Auxiliary devices for dental procedures

The present disclosure relates to an auxiliary device for a dental procedure, and more particularly, to an auxiliary device for a dental procedure capable of securing a treatment field by pushing or pulling a patient's soft tissue in a specific direction while inhaling by-products in the oral cavity. About.

In general, during dental treatment, foreign substances such as water, saliva, blood, etc. continue to accumulate in the oral cavity of a patient during the treatment. If such foreign substances remain in the oral cavity, the working field of vision is not secured and the probability of viral infection or bacterial disease occurring at the treatment site is increased. Therefore, it is necessary to remove foreign substances generated during a dental procedure using suction. In addition, a retraction operation of pushing or pulling a patient's soft tissue in a specific direction through a retractor, such as a tongue or cheek, is required in order to secure a working field of vision for a treatment area during dental treatment.

That is, during a dental procedure, for smooth treatment, it is necessary to secure a working field of view of the treatment area by pushing or pulling the patient's soft tissue through a retractor operation and suctioning 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 by a doctor alone without the help of a dental hygienist, and the retractor work and suction work are merely auxiliary work, so there is a problem that the worker's motivation to work is lowered. .

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