| titleOfInvention | Upper anterior tooth 90-degree torsion appliance and preparation method thereof |
| abstract | The invention discloses an upper anterior tooth 90-degree torsion appliance and a preparation method thereof, and 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. The preparation method comprises the following steps: preparing an upper and lower jaw working model; finishing the working model; the curved lip side draws hook and two side back teeth arrow point snap rings, adopts novel injection molding process preparation to rescure ware resin base, and arrow point snap ring and draw hook tongue side all bury in the resin base, and the base extends to and twists reverse the tooth and far in, forms integrated structure with far in adjacent face baffle. The appliance prepared by the invention can efficiently solve the problem of severe torsion when the upper anterior teeth of children are erupted, thoroughly avoid the far and middle movement of the twisted teeth and the loss of the gap between the missing teeth, and ensure that the children patients are comfortable to wear. |
