Technical Field
[0001] The utility model relates to the technical field of oral medical devices, in particular to a lip bumper adjustable screw functional regulator. Background Art
[0002] A lip bumper appliance is a medical device applicable to cases of mild maxillary hypoplasia, with a basically normal or slightly protruded mandible. Its main purpose is to stimulate maxillary development and inhibit mandibular development. Existing lip bumper appliances mainly consist of a lip bumper, a lingual arch, a buccal screen, a occlusal rest, and a double-curved lip arch. The lip bumper is located between the outer side of the maxillary gingiva and the inner side of the lip, leaving a gap from the gingiva, so that the soft tissue between them is subjected to tensile stress, which can achieve the effect of stimulating maxillary development. The connecting wire is used to connect the buccal screen and the lip bumper. The lingual arch is located inside the maxillary anterior teeth and can push the maxilla to grow outward. The buccal screen is located outside the maxillary and mandibular posterior teeth, leaving the maxilla and closely contacting the mandible, interacting with the lip bumper to more effectively stimulate maxillary development and inhibit mandibular development. The occlusal rests are respectively located on the four strong molars of the upper and lower jaws, and there is a gap between the upper and lower jaws, which can not only open the bite and promote tooth growth, but also stabilize the position of the appliance in the oral cavity.
[0003] Since most of the objects of lip bumper treatment are children, and the lips of children are in a rapid development period, the gap between the lip bumper and the gingiva is not enough to drive the next cycle of maxillary development. In order to avoid this situation, it is necessary to regularly replace the new lip bumper appliance. However, the replacement of the lip bumper appliance is relatively cumbersome. Frequent replacement is not only cumbersome and inconvenient, but also increases costs. Therefore, it is necessary to propose a lip bumper adjustable screw functional regulator.
