Technical Field

The utility model relates to the technical field of medical appliances, in particular to a polytype adjustable bite-block.

Background

The bite plate is the most conservative means for treating temporomandibular joint disorder, and is also the most commonly used means for treating temporomandibular joint disorder clinically. The occlusal pad is mainly worn on the teeth of the upper row or the lower row, comprises hard or soft occlusal pad and has different functions according to different materials. The bite pad mechanically isolates direct contact between the upper and lower teeth to raise the bite, and the joint moves slightly downward with the teeth of the mandible to open the gap between the joint to relieve the joint pressure. The positions of the joints are adjusted through the positions of the occlusal pads, so that the condyle and the joint disc are consistent, the positions of the joints are adjusted, and the symptoms of patients are relieved.
