Expander for orthodontics

Abstract

The invention discloses an orthodontic expander, which belongs to the technical field of expanders, and comprises a storage box, a protective pad, a tongue depressor, a tongue depressor, a tongue depressor, a tongue depressor, a tongue depressor, a tongue depressor, a tongue depressor, a tongue depressor, a tongue depressor, a tongue depressor, a tongue depressor, a tongue depressor and a tongue depressor, the upper supporting plate is obliquely arranged and used for pressing the tongue inside the oral cavity, and the refreshing mechanism is installed below one side of the upper supporting plate; by arranging the tongue depressor, the rotating rod and the torsional spring, when the oral cavity of a patient is opened, medical staff can turn over the tongue depressor upwards, so that the tongue depressor rotates under the action of the rotating rod and compresses the torsional spring, and then the tongue depressor can be loosened after the oral cavity of the patient is opened through the expanding device; due to the fact that the tongue depressor is obliquely arranged, the tongue of the patient is pressed and limited, and the situation that work of medical staff is affected during orthodontic treatment is avoided.

Description

technical field [0001] The invention belongs to the technical field of spreaders, and in particular relates to a spreader for orthodontics. Background technique [0002] The oral cavity is the initial part of the digestive tract. It communicates with the outside world through a cleft in the front, and connects with the pharynx through the isthmus in the back. There are teeth, tongue and other organs in the oral cavity. The front wall of the oral cavity is the lips, the side walls are the cheeks, the top is the palate, The floor of the oral cavity is composed of mucous membranes and muscles. The oral cavity is divided into the oral vestibule of the anterolateral part and the intrinsic oral cavity of the posterior medial part by the upper and lower dental arches. If there is a problem in the oral cavity, or when the dental deformity is corrected, an oral expander is required. [0003] However, in the actual use of the existing orthodontic expander, because the patient's tongue...

Problems solved by technology

[0004] The object of the present invention is to provide an orthodontic expander to solve the problem that the existing orthodontic expander proposed in the above-mentioned background technology has problems when performing orthodontic care on the inside of the patient's oral cavity during actual use. Failure to press and limit the patient's tongue makes it easy for the medical staff to affect the work of the medical staff if the patient's tongue moves during the nursing process, reducing work efficiency; at the same time, the existing orthodontic expansion support The protective effect of the device is poor in the actual use process. Because the oral cavity of the patient needs to be opened for a long time during the oral care of the patient, the mouth is not stressed and the patient's oral wall is sore, causing discomfort, fatigue, and inconvenient Problems with patient activity
