Problems solved by technology

However, the author believes that it is difficult to treat skeletal Angle’s class III malocclusions with anti-Twinblock, because it is not easy to establish a three-dimensional wax joint record to make the mandible recede
In order to overcome the inability of the cranium-chin pocket appliance to treat high-angle cases and the complications caused by improper application, the present invention designs a new functional appliance

Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0013] according to figure 1 , figure 2 , image 3 and Figure 4 It can be known that the posterior inclined guide plate appliance is composed of two inclined guide plates, the upper and lower inclined guide plates in the bilateral posterior tooth area, the retention snap ring 3, the base 4 and the plastic connector. The retaining clasp 3 extends from the palatal and lingual sides, and is connected with the base 4 through a plastic connector. The long inclined surface 1 of the upper jaw and the long inclined surface 2 of the lower jaw are made of plastic. The retention snap ring 3 provides retention. The orthodontic screw expander 6 can expand the upper dental arch or the middle seam of the palate. The connection relationship is as follows, upper jaw: the upper jaw long slope 1, the retaining clasp 3 and the base 4 are connected by a plastic connecting body. Ma...

Abstract

The cheek tooth slope guide board appliance consists of upper and lower long slope guide boards in the cheek tooth areas of both sides, fixing clamp ring, base support and connecting plastic body. The upper long slopes and the lower long slopes are connected to the base support in palate side and tongue side separately; are connected with the fixing clamp ring and base support in the upper palate and the lower palate side separately via plastic; and the correcting spiral expander is used to expand the upper dental arch or sutura palatina mediana. The present invention has simple structure and convenient use, and may be worn all the day to result in fast treating effect.

Description

technical field [0001] The invention relates to an orthodontic device for posterior tooth inclined-plane guide plate, which is especially suitable for patients with functional or mild and moderate Angle's Class III skeletal mandibular protrusion in the growth and development period. Background technique [0002] At present, it is generally believed that bony mandibular protrusion is relatively difficult to treat (Treatment response to maxillary expansion and protraction, Eur J Orthod, 1996, 18:151). For patients with Angle's Class III malocclusion in the growth and development period, the headgear-chinen pocket appliance can be used to change the growth direction of the mandible by rotating the mandible downward and backward. The indications for the headgear-chinnoid appliance are patients with Angle's Class III malocclusion with a short lower 1 / 3 of the face and mild mandibular hyperplasia during growth and development. However, improper use of the ...
