Abstract
In a tooth moving method and appliance for securing a space for an incoming permanent tooth to erupt, there are provided two lingual buttons to be fixed to two teeth, respectively, to spread out a space therebetween or correct a dentition therebetween; an inner wire to be pivotally connected to one lingual button at an end thereof; a tube to be loosely fitted onto the inner wire and pivotally connected to the other lingual button at an end thereof; an open coil loosely fitted onto the tube; and a split stop for adjusting tensile force of the open coil, whereby tensile force of the open coil is adjusted by the split stop to move at least either of the two teeth, so as to spread out the space therebetween to a desired extent.
Claims4
A tooth moving method wherein two lingual buttons are fixed to two teeth, respectively, to spread out a space therebetween or correct a dentition therebetween;
- an inner wire is pivotally connected to one of the two lingual buttons at an end thereof;
- a tube loosely fitted onto the inner wire is pivotally connected to the other lingual button at an end thereof;
- and an open coil is loosely fitted onto the tube, whereby a tensile force of the open coil is adjusted by a split stop to move at least either of the two teeth, so as to spread out the space therebetween to a desired extent.
A tooth moving appliance comprising two lingual buttons to be fixed to two teeth, respectively, to spread out a space therebetween or correct a dentition therebetween;
- and space-spreading biasing means to be mounted between the two lingual buttons, the space-spreading biasing means comprising an inner wire to be pivotally connected to one lingual button at an end thereof;
- a tube to be loosely fitted onto the inner wire and pivotally connected to the other lingual button at an end thereof;
- an open coil loosely fitted onto the tube;
- and a split stop for adjusting tensile force of the open coil.
