A kind of cr plate and its repositioning occlusal plate manufacturing method

Abstract

The application discloses a CR plate, which includes an upper brace worn on the upper dentition, a lower brace worn on the lower dentition, and a positioning pin, the positioning pin is located on a section of the end surface of the upper brace close to the lower brace, or the positioning pin is located on the lower brace. The brace is close to the end face of the upper brace. Also disclosed is a method for making a repositioning occlusal plate, which includes the following steps: Step 1: Take an impression in the patient's mouth; Step 2: Make a plaster model according to the impression; Step 3: Put the above-mentioned CR plate in the patient's mouth, and the patient looks for Bite the upper and lower jaws in the treatment position, bite out the marking points on the upper braces, take out the upper braces from the patient's mouth, dig grooves at the marked points on the upper braces, and put on the upper braces after the grooves are completed; Step 4: On the upper teeth Fill the occlusal recording silicone between the column and the lower dentition, wait for the occlusal recording silicone to solidify and take it out; Step 5: Make and reposition the occlusal plate. This application can accurately find the previously set treatment position when filling the bite registration silicone.

Description

technical field [0001] The present application relates to the field of repositioning occlusal plates, in particular to a CR plate and a manufacturing method of repositioning occlusal plates. Background technique [0002] Temporomandibular joint disc displacement (anterior disc displacement, ADD) is a common clinical disease in stomatology, which refers to the forward displacement of the articular disc beyond its normal position when the cusps are crossed. Patients with ADD may experience pain, snapping, and abnormal jaw movement in the temporomandibular joint (TMJ). According to whether the disc-condyle relationship can return to normal when the mouth is opened, ADD is divided into reversible and irreversible anterior displacement, that is, during the opening process, the articular disc can bounce back to restore the normal disc-condyle position relationship. It is reversible anterior disc displacement; after the condyle slides forward and downward, the articular disc canno...

Problems solved by technology

In fact, when the two jaws are closed after the occlusal recording silicone is put in, it is difficult for the two jaws to find the treatment position before the occlusal recording silicone is put in, and there is a deviation from the position before it is put in, which will affect the repair function of the later repositioning of the occlusal plate.
