Abstract
The invention provides a bracket having horizontally extending tabs that allow the arch wire to be ligated in either an active or passive manner using a ligation device such as an elastomeric band, metal ligature tie or the like. For an active ligation the ligation device is wrapped behind the tabs to press the arch wire into the bracket groove, and for a passive ligation the ligation device is wrapped in front of the behind two tabs that are diagonally oriented across the bracket groove, without pressing the arch wire into the bracket groove, or pressing the arch wire into the groove with a reduced force compared to the active ligation.
Claims10
A bracket having horizontally extending tabs that allow an arch wire to be ligated in either an active or passive manner using a ligation device;
- the bracket includes four tabs in a rectangular pattern and a bracket groove, and for an active ligation the ligation device is wrapped around the four tabs to press the arch wire into the bracket groove, and for a passive ligation the ligation device is wrapped around two first tabs which are opposite the bracket groove and not around two second tabs which are opposite the bracket groove, without pressing the arch wire into the bracket groove, or pressing the arch wire into the groove with a reduced force compared to the active ligation.
A bracket having horizontally extending tabs that allow an arch wire to be ligated in either an active or passive manner using a ligation device:
- the bracket includes a base a back surface for securement to a tooth and a front surface and having a bracket groove across the front surface for receiving an arch wire extending across the base and two first tabs extending from the front surface of the base, the two first tabs arranged on opposite sides of the bracket groove, and at least one second tab extending from the front surface of the base, and for an active ligation the ligation device is wrapped on a side of the two first tabs and the at least one second tab opposite the bracket groove to press the arch wire into the bracket groove, and for a passive ligation the ligation device is wrapped on a side of the two first tabs opposite the bracket groove and located on a side of the at least one second tab closest to the bracket groove.
