SPONTANEOUS ERUPTION DEVICE OF ECTOPIC IMPACTED TOOTH

摘要

Disclosed is a device for recovering eruption of an ectopic-impacted permanent tooth, which normally restores an eruption direction when a permanent tooth is caught by another neighboring permanent tooth or a milk tooth and thus, is abnormally erupted. According to the present invention, the device comprises: a bridge attached to a chewing surface of a permanent teeth to be treated; a pushing member installed in the bridge to axially move and having a contact pad attached to one end part exposed out of the bridge and a ring formed at the other end part; and an elastic member hung between the bridge and the ring of the pushing member. Since the elastic member axially applies elasticity to the pushing member so that the bridge attached to the tooth to be treated receives force in the direction for pushing out an adjacent milk or permanent tooth by using the adjacent milk or permanent tooth as a support, interference with a milk tooth or another permanent tooth is avoided in eruption, thereby realizing normal eruption of the permanent tooth to be treated.
