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

Example Embodiment

[0012] The present invention will be further described in detail below in conjunction with the drawings:

[0013] according to figure 1 , figure 2 , image 3 with Figure 4 It can be seen that the posterior bevel guide appliance is composed of the upper and lower bevel guides of the bilateral posterior area, the retaining ring 3, the base 4 and the plastic connector. The maxillary long bevel 1 and the mandibular long bevel 2 are respectively in the upper jaw or the lower jaw. The retaining ring 3, the palate and the lingual side extend, and are connected to the base 4 through a plastic connecting body as a whole. The upper jaw long inclined plane 1 and the lower jaw long inclined plane 2 are made of plastic. The retaining ring 3 provides retention. The orthodontic spiral expander 6 can expand the upper dental arch or the palatal seam. The connection relationship is as follows, the upper jaw: the upper jaw long inclined plane 1, the retaining ring 3 and the base 4 are connected b...

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 ...
