Technical Field

The present application relates to the field of repositioning bite plates, and more particularly to a CR plate and a method of making a repositioning bite plate thereof.

Background

Anterior displacement of temporomandibular joint disc (ADD) is a common clinical condition in stomatology, which means that when the cusps are dislocated, the joint disc is displaced forward beyond its normal position. Patients with ADD may experience pain, ringing, and abnormal jaw movements in the temporomandibular joint (TMJ) area. According to whether the disc-condyle relationship can be recovered to be normal during opening, ADD is divided into reducible and irreducible anterior displacement, namely in the opening process, a disc-condyle position relation person with the joint disc capable of rebounding backwards to recover to be normal is called reducible anterior displacement of the disc; when the condyle slides forward and downward, the articular disc can not rebound backward and still is in a forward displacement state, which is called the irreversible disc forward displacement.

Early attainment of a consistent and stable reduction of the articular disc is critical to the treatment of anterior discal replacement, which is often facilitated by the use of a repositioning bite plate. The repositioning bite plate is typically worn on the upper jaw and has a baffle with a beveled surface. When a patient is actively bitten by chewing and the like, the inclined plane can guide incisors in the lower jaw to move forwards and downwards, further the lower jaw is induced to extend forwards to enable the condyles to move forwards and downwards, the joint discs which are moved forwards are captured, and the normal disc-process relation is reconstructed.

The fabrication of the repositioning bite plate requires collecting the occlusion relationship in the mouth of the patient, placing the occlusion recording silica gel into the mouth of the patient during collection, biting the patient on the occlusion recording silica gel, and fabricating the repositioning bite plate according to the collected occlusion recording.

Before the occlusion recording silica gel is placed in a patient mouth, the patient needs to find a position where the bounce disappears or is relieved when the patient opens and closes the mouth, the position is called a treatment position, after a treatment position is often found in the acquisition process, the patient needs to open the two jaws and then place the occlusion recording silica gel in the patient mouth, and the patient closes the two jaws to bite on the occlusion recording silica gel according to muscle memory of the just found treatment position. In fact, when the double jaws are closed after the occlusion recording silica gel is placed, the double jaws are difficult to find a treatment position before the occlusion recording silica gel is placed, deviation exists between the treatment position and the position before the occlusion recording silica gel is placed, and influences are caused on the repair function of the bite plate which is repositioned at the later stage.
