Maxillary occlusal pad-lip shield appliance

Abstract

The invention discloses a maxillary occlusal pad-lip shield appliance, which comprises a base plate arranged at the front part of a hard jaw, and the front end of the base plate is provided with a reverse slope guide plate or a hyperbolic reed; the pair of maxillary occlusal pads are respectively arranged on the two sides of the base plate, are respectively positioned at the back tooth retreat positions on the two sides of the maxillary, and are connected with the back teeth through retention devices; the pair of upper lip stoppers is connected to the base plate through connecting pieces and located at vestibular sulcus positions on the two sides of the upper jaw respectively. The orthodontic device disclosed by the invention is beneficial to prevention and blocking of mild bone class III and functional class III malocclusion of patients in a tooth replacement stage and a constant-pressure early stage, and the wearing comfort of the patients is remarkably improved while the orthodontic treatment effect is realized.

Description

technical field [0001] The invention belongs to the field of orthodontics, and more particularly relates to a maxillary occlusal pad-lip blocking appliance. Background technique [0002] Class III malocclusion is one of the most common malocclusions in clinical practice, and it can be aggravated with growth and development. Early intervention is often recommended for such patients. It is clinically found that the mandible of Class III patients in partial mixed dentition and early constant pressure can be retracted or only with mild skeletal crossbite. It is expected to prevent / block mild skeletal Class III and functional Class III malocclusion through early correction. Deformed purpose. At present, there are various types of functional appliances commonly used in early orthodontic treatment, but all of them have different degrees of problems, such as difficulty in adapting to patients with larger appliances, unsuitable appliances for daytime wearing, appliances affecting ea...
