Embodiment Construction

[0022] refer to figure 1 , the spring-type mandibular protrusion appliance includes a spring 1, a spring sleeve 2, a sliding rod 3 for connecting with a mandibular arch wire, a fixing rod 4 and a positioning nut 5 for fixing with the maxillary molar belt ring, and a spring sleeve 2 It consists of a sliding fit inner tube 6 and an outer tube 7. The end of the inner tube is welded with a snap ring 8, and the end of the outer tube is cast with a connecting ring 9. A small hole is provided on the connecting ring 9. The spring 1 is set in the spring sleeve Outside the pipe 2, its two ends are offset against the connecting ring 9 of the outer tube of the spring sleeve and the snap ring 8 of the inner tube respectively. Fixed rod 4 is " L " type, (see figure 2 ), the end of the curved section expands, and the long rod section passes through the aperture of the connecting ring 9 on the spring sleeve. slide bar 3 as image 3 As shown, one end has a "U"-shaped hook, and the middle s...

Abstract

The invention discloses a protrusive rectifier of spring-typed submandibular, which comprises the following parts: spring, spring sleeve, sliding rod in connection with the mandibular arch yarn, fixing rod and location nut to fix the maxillary ground band, wherein the spring sleeve and sliding rod constitute a similar of device artificial knuckle, which matches the normal rectifier on the maxillary ring band and mandibular arch yarn to make the mandibular part be forced to ascend; the location nut can control the mandibular protrusive quantity and direction precisely through adjusting the sliding rod.

Description

technical field [0001] The invention relates to a medical device, in particular to a spring-type mandibular protruding appliance. Suitable for orthodontic patients treated with fixed appliances. technical background [0002] The incidence rate of malocclusion in my country is 29%-49%. Among them, Angle's class II malocclusion refers to a type of malocclusion in which the mandible and lower dental arch are in the distal position, accounting for 20%-30% of malocclusion patients. . The main clinical manifestations are mandibular retrusion, maxillary protruding anterior teeth with large overbite coverage, open lips and teeth, etc. These patients have poor facial shapes and urgently need orthodontic treatment. Clinically, patients with mandibular retrusion who are in the growth and development stage can be treated with functional appliances. [0003] Animal experiments and clinical applications have confirmed that changing the position of the jaw can produce significant bone ch...
