Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] The invention discloses a device for bilaterally depressing posterior teeth, which utilizes micro-implants in the palatal suture as anchorages to simultaneously depress the posterior teeth on both sides of the maxilla without interfering with the posterior teeth during the depressing process (conventional methods are used for depressing the posterior teeth). During the process, the buccal inclination of the molars to be depressed may occur, resulting in occlusal interference), and sagittal force can also be applied during the depression process to improve the class II relationship of the molars. The elongation and inclination of the anchorage teeth and a series of problems caused by the orthodontic pressing method in the prior art are avoided. The posterior teeth that are connected by the device for bilaterally depressing the posterior t...

Abstract

The present invention provides a double-side depressing molar teeth device, and belongs to the field of dental medical device. The double-side depressing molar teeth device comprises a pair of side support bars (1) and a connecting rod between them (2), and two micro-implants (6) implanted in the jaw joints side by side and located in the root of the first molar tooth. The connecting rod (2) is fixedly arranged between the rear ends of the side support bars (1) on both sides; each side support rod (1) is provided with three connectors (3), the front end of each side support rod (1) is provided with a front towing hook (4), each of the side support rod (1) is provided with a towing hook (5) close to the second molar; and rubber bands (7) are respectively arranged between the front hook towing hook (4) and micro-implants (6), and between rear towing hook (5) and micro-implants (6). The double-side depressing molar teeth device of the invention has the advantages of stable treatment effect, no side effects, improvement of patient comfort during treatment, low surgical risk, little trauma, and easiness to production and promotion.

Description

technical field [0001] The invention relates to a device for oral orthodontics, in particular to a device for bilaterally depressing posterior teeth, which belongs to the field of oral medical devices. Background technique [0002] In orthodontic treatment, vertical depression of the posterior teeth is required early in treatment for Angle Class II high-angle patients and open-close patients. The traditional methods include posterior occlusal pad, high head cap, MEAW, and micro-implant anchorage. The cooperation of the patient is required for the pads and high-position headgear, and the force is intermittent, so the treatment effect is not good and the course of treatment is long. MEAW is mainly the elongation of the front teeth and the erection of the back teeth, and cannot really achieve the depression of the molars. Micro-plant anchorage can be strengthened early and the effect is significant, but in the traditional method, at least 4 implant nails need to be implanted,...
