Description

Mouth Retractor

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oral retractor, and more particularly to an oral retractor used mainly for expanding the oral cavity in dental treatment.

A retractor is used to facilitate the treatment by widening a window or incision in a procedure, particularly during surgery or surgical procedures.

Implant or other dentistry is performed with the maxillary or mandibular lips tilted so that the patient's mouth is wide open in order to obtain sufficient visual field during the surgical procedure.

However, if the patient unconsciously slits or moves his or her mouth or tongue during a patient's open-mouth treatment, it will cause considerable disruption to the patient's medical care.

Therefore, in various dental treatments, the retractor is used to secure the visibility in the oral cavity of the patient and to maintain the patient's open mouth for smooth operation.
