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, in particular to a film-pressed posterior ortholocking jaw correction device. Background technique [0002] Lockjaw is a common malocclusion in orthodontics. It is more common in permanent dentition and less common in deciduous teeth. Ortholocking of the second permanent molars is common. The clinical manifestations are mostly buccal inclination of maxillary molars and normal or slightly lingual inclination of mandibular molars. Lockjaw is very harmful, mainly in the following aspects: 1. Due to the lack of normal chewing function of the locked teeth, the chewing function is reduced 2. It is easy to occur occlusal trauma , loose and worn teeth 3. Limited lateral movement of the mandible in locked patients; 4. Easy to induce temporomandibular joint disorder . 5. Affect the shape of the face. The traditional orthodontic method is generally corrected by the interactive traction of the upp...
