Abstract
A tooth moving method and appliance for securing a space for an incoming permanent tooth to arrive includes two lingual buttons to be fixed to two teeth, respectively, to spread out a space therebetween or correct a dentition therebetween. An inner wire is pivotally connected to a first lingual button at an end thereof, and a tube is loosely fitted onto the inner wire and pivotally connected to the other lingual button at an end thereof. An open coil is loosely fitted onto the tube, and a split stop is provided for adjusting the tensile force of the open coil. Thus the 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.
Claims9
A method of moving teeth, comprising:
- fixing a first button to a first tooth in one of an upper jaw and a lower jaw;
- fixing a second button to a second tooth in the one of the upper jaw and the lower jaw;
- pivotally connecting a basal end of an inner wire to the first button;
- fitting a tube onto the inner wire, and pivotally connecting a basal end of the tube to the second button;
- fitting an open coil onto the tube so that the open coil applies a pushing force against the first button and the second button so as to thereby apply a pushing force of separation against the first tooth and the second tooth;
- and
- adjusting the pushing force of the open coil using at least one stop fitted onto the tube.
A tooth-moving apparatus comprising:
- a first button to be fixed to a first tooth in one of an upper jaw and a lower jaw;
- a second button to be fixed to a second tooth in the one of the upper jaw and the lower jaw;
- and
- a biasing device to be mounted to said first button and said second button, said biasing device including:
- an inner wire having a basal end to be pivotally connected said first button;
- a tube to be fitted onto said inner wire, and having a basal end to be pivotally connected to said second button;
- an open coil to be fitted onto said tube so as to apply a pushing force against said first button and said second button so as to thereby apply a pushing force of separation against the first tooth and the second tooth;
- and
- at least one stop to be fitted onto said tube for adjusting the pushing force applied by said open coil against said first button and said second button,
- wherein each of said first button and said second button has a neck said neck of each of said first button and said second button having wide end portions and a narrower middle portion between said wide end portions, said basal end of said inner wire being connected to said narrower middle portion of said neck of said first button, and said basal end of said tube being connected to said narrower middle portion of said neck of said second button.
