摘要:
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.
