Power chain used for anterior segment retraction
Elastomeric chain rendering 160 g/side extending between mini-screw implant and a hook crimped on 0.017- by 0.025-inch stainless steel wire distal to the lateral incisor.
T-loop fabricated to perform anterior segment retraction
In the frictionless group, anterior segment retraction was done using closing T-loops fabricated from 0.017- by 0.025-inch titanium molybdenum alloy (TMA) wire rendering comparable retraction force.
