| titleOfInvention | 90-degree torsion appliance for upper anterior teeth |
| abstract | The utility model discloses an upper anterior teeth 90-degree torsion appliance, which belongs to the technical field of tooth correction. Comprises a lip side traction hook and a torsion tooth near and far middle tongue side buckle, an elastic rubber ring is arranged between the lip side traction hook and the torsion tooth near and far middle tongue side buckle, a far middle and near surface guide plate is arranged in a gap between the torsion tooth far and middle buckle, and retention devices arranged on double-side upper jaw molars are arrow snap rings. The labial traction hook and the arrow snap ring are embedded in the maxilla-palatal resin base. When in preparation, an upper and lower jaw working model is required to be prepared; then, trimming the working model; then bending a labial traction hook and a bilateral posterior tooth arrow snap ring; and finally, manufacturing the resin base of the appliance by adopting a novel injection molding process, wherein the arrowhead snap ring and the tongue side of the traction hook are embedded in the resin base, and the base extends to the far middle of the torsion tooth to form an integrated structure with the far middle adjacent surface guide plate. The utility model discloses a severe torsion problem that takes place when correcting ware ability efficient solution children go up the anterior teeth and sprout thoroughly avoids twising reverse the tooth and remove far and middle, loses the edentulous clearance to it is comfortable to make children's patient wear. |
