ORTHODONTIC APPARATUS FOR MALOCCLUSION

摘要

The present invention relates to a maxillary orthodontic apparatus for treating malocclusion with prognathic mandible (class III malocclusion), in which the maxilla is posteriorly placed in relation to the normal mandible. The maxillary orthodontic apparatus of the present invention comprises: an upper base which is inserted into the maxillary teeth; a lower base which includes a support wire connected to be spaced apart therefrom in front side thereof, and is inserted into the mandibular teeth; and a traction means which connects the upper base to the support wire so that the maxilla can be towed in a front upper direction with respect to the prognathic mandible. The traction means includes: first and second latching parts included in the upper base; first and second traction parts included in the support wire; a first elastic member which connects the first latching part to the first traction part so that the upper base can be pressed forward; and a second elastic member which connects the second latching part to the second traction part so that a front end portion of the upper base can be lifted upward using the support wire as a support point. Accordingly, the maxillary orthodontic apparatus of the present invention allows the maxilla and mandible to be arranged in appropriate positions without requiring an additional orthodontic treatment on the maxilla to be arranged in a normal position.
