Optimizing Anterior En Masse Retraction with Miniscrew Anchorage

Figure 10

(a, b, c) Simultaneous en-masse retraction was continued in both arches. Closed coil springs were used for the en-masse retraction which were stretched and engaged posteriorly over MSPA and anteriorly to hook soldered on archwire. Although miniscrews were placed towards occlusal level, forces exerted by the springs were directed apically and towards Cres of posterior teeth.
