Inclined plane guide plate

Abstract

The invention discloses an inclined plane guide plate. The inclined plane guide plate comprises a base body and a fixing device, wherein an inclined plane is arranged at the front side of the base body; the fixing device comprises a front fixing part, a side fixing part and a rear fixing part; one end of each of the front fixing part, the side fixing part and the rear fixing part is fixed on the base body; the front fixing part, the side fixing part and the rear fixing part are located at the front side, the side face and the rear side of the base body respectively; an elastic part is arrangedin the middle of the rear fixing part; the elastic part is provided with a U-shaped groove. The inclined plane is arranged at the front side of the base body so that back teeth are out of touch whenfront teeth are occluded on the inclined plane, a jaw distance is increased and the tension on muscle of a maxillofacial region is increased; upper and lower teeth are separated and have no occlusioncontact, so that vertical growth of the back teeth and peripheral alveolar socket tissues can be promoted and the inclined plane guide plate is very good for correcting deep overbite and deep coverage; the elastic part is arranged in the middle of the rear fixing part so that the front teeth are fixed and corrected in a utilization process of the guide plate; the U-shaped groove can be used for adjusting the position of the inclined plane guide plate in a mouth according to an adduction distance of the front teeth of an upper jaw and various correction can be carried out at the same time.

Description

technical field [0001] The invention belongs to a medical device for dental correction, in particular to an inclined guide plate. Background technique [0002] Deep overbite is an abnormality in the vertical relationship of the upper and lower dental arches, which refers to the case where the incisal margin of the upper anterior teeth covers 1 / 3 of the crown length of the lower anterior teeth or the lower anterior teeth occlude more than 1 / 3 of the lingual side of the upper anterior teeth By. According to the degree of overlay, it is divided into 3 degrees; among them, degree II: the upper anterior teeth cover more than 1 / 2 to 2 / 3 of the crown length of the lower anterior teeth, or the lower anterior teeth occlude 1 / 2 of the lingual incisor of the upper anterior teeth Above to 2 / 3 of the place (such as the protruding tongue). The existing orthodontic methods include: lingual plate prying method, deciduous tooth grinding method, mandibular slope guide plate, hyperbolic tong...

AI Technical Summary

Problems solved by technology

The existing orthodontic methods include: lingual plate prying method, deciduous tooth grinding method, mandibular slope guide plate, hyperbolic tongue-reed pad type appliance, functional appliance FRⅢ, etc. The above-mentioned orthodontic methods have their own indications. The hyperbolic tongue-reed occlusal appliance is commonly used for deciduous anterior crossbite, which simply uses the mechanical push spring to push the crossbite forward. Although it has a wide range of applications, the deciduous teeth are short and poorly positioned, and it restricts the development of the mandible. , to promote the normal development of the maxilla and other reasons, the use is limited
