not to use any type of bracket ligature other than the conventional elastic ligatures available in the practice.
The use of Silness and Loe's VPI (8) instead of Quigley and Hein's (14) plaque index (as modified by Turesky, Gilmore and Glickman) (15) was due to the requirement for plaque disclosure in the latter, which implies the need for a prophylaxis to remove the disclosing agent or the substitution of stained elastic ligatures.
Traditional braces require metal or elastic ligatures
to hold arch wires in place and require frequent adjustments or "tightening.
Designed with sophisticated engineering and space-age material, these braces use a unique clip to hold the wires in place without elastic ligatures, yet carefully regulate force.
Although conventional braces are still a good option, braces without elastic ligatures allow the use of lighter force, which can move teeth into position more efficiently and comfortably, shorten overall treatment time and may mean fewer and quicker visits for adjustments.
Since they do not use elastic ligatures, self-ligating braces may need adjusting only every two or three months, depending on the stage of treatment.
Unlike conventional braces that require metal or elastic ligatures
to hold archwires in place, the high-tech Damon System uses tie-less braces that do not require as frequent adjustments or "tightening.
