Orthodontic treatment is considered successful only if optimal esthetic and
function are achieved.The objective of this study was to compare facial soft tissue profile changes
produced by a new technique (elastic forces based on skeletal anchorage
mini-plates) with changes
produced by conventional class-II elastic forces.
The purpose of this study is to evaluate the effects of laceback
ligatures on the anteroposterior and vertical position of the upper incisors
and the mesial position of the upper first molars during the alignment and
leveling stage of orthodontic
treatment of Class II Division 1 cases which
require extraction of upper first premolars. This study was Randomized
controlled trial (RCT).
