Description

Orthodontic mouth opener

Technical Field

The utility model relates to the technical field of oral medical treatment, in particular to an oral orthodontic mouth opener.

Background Art

An oral opener, also known as a mouth opener, is an instrument used to open the oral cavity during orthodontic treatment. The mouth opener body is elastic, and the two side arms of the mouth opener body can bend toward the inside or outside of the mouth opener body when subjected to external pressure. When the external pressure disappears, the two side arms of the mouth opener body return to their original positions. A disposable oral opener with this structure has a simple structure, is easy to operate, and is low in cost. It is suitable for use in various oral medical institutions, and is particularly suitable for use in oral medical operations.

The existing (Announcement No. CN216797927U) discloses an oral orthodontic opener, which uses an upper lip embedding groove and a lower lip embedding groove on the left and right sides adjusted by a threaded rod to adjust the oral tension support. Although it satisfies the requirement of adjusting the appropriate angle to make the oral cavity obtain the most comfortable opening degree and relieve the fatigue of the patient's facial muscles to the greatest extent, it is worth noting that the upper lip embedding groove and the lower lip embedding groove need to be placed in the oral cavity, and the position of the threaded rod is not convenient for medical staff to adjust, and there is a blind spot in the oral cavity. In addition, the elastic force of the conventional opener will not only cause facial muscle fatigue to the patient as mentioned in the above application, but also lack stability and buffering protection during the use of the opener.
