Embodiment 1

[0028] A compression film type posterior orthodontic jaw correction device, which is assembled from three parts: a retaining device, a connecting device, and a traction device. The retaining device is composed of a compression film type maxillary posterior jaw pad 3 and surrounding anchorage teeth It is composed of diaphragm 1 and palatal base 2 of the labial and palatal mucosa. The thickness of diaphragm 1 is 1.0mm. According to the undercut condition of the anchored teeth, the diaphragm 1 can be used in the cheeks of the central incisors, canines and first molars. The surface is designed with resin-retained protrusions 4, the shape of the resin-retained protrusions 4 is rectangular, mushroom or elliptical; the connecting device consists of a U-shaped curved transverse palate rod 5 embedded in the posterior jaw pad 3 and embedded The force-increasing wire 7 in the palatal base 2 is composed of the end of the transverse palate rod is embedded in the posterior jaw pads on both si...

Abstract

The invention provides a pressed-film-type back tooth locked occlusion correcting device and a preparation method thereof. The device is prepared by assembling a retention device, a connection device and a traction device; the retention device is composed of pressed-film-type upper jaw back jaw pads, a membrane wrapping and surrounding anchorage teeth and side mucosae of the lip palate and a palatal-side base support; the connection device is composed of a U-shaped curved transpalatal arch of which the tail end is embedded into the back jaw pads and a reinforcing wire embedded into the palatal-side base support, and the tail end of the transpalatal arch is embedded into the back jaw pads on the two sides; the traction device is composed of traction hooks which are welded to the two sides of the U-shaped curved bottom of the transpalatal arch, wherein the positions of the traction hooks directly face the positions at one half of the mesiodistal sides of the tongue sides of occlusion teeth and are 5 mm away from the palatal side neck edges of the occlusion teeth. The pressed-film-type back tooth locked occlusion correcting device is easy to operate, little in dependency on a patient and good in correcting effect.

Description

Technical field [0001] The invention belongs to the technical field of oral devices, and in particular relates to a pressure film type posterior orthognathic orthodontic device. Background technique [0002] Locked jaw is a common malocclusion deformity in orthodontic clinics. It is more common in permanent dentition and rarely in deciduous teeth. It is often caused by the premature loss of individual deciduous molars, retention or abnormal position of permanent tooth germs, resulting in dislocation eruption. The positive locking jaw of the second permanent molar is common. Most of the clinical manifestations are that the upper molars are inclined to the buccal, and the lower molars are in normal or slightly inclined tongue. Locked jaw is very harmful, mainly in the following aspects: 1. Because the locked teeth have no normal mastication function, the mastication function is reduced 2. It is easy to occur Bite trauma , Loose and wear teeth 3. Limited lateral movement of the man...
