Miniscrews for En-masse retraction

Bimaxillary dentoalveolar protrusion is a condition that results from the proclined and protruded maxillary and mandibular anterior teeth. Maximum anchorage is needed in such cases to retract upper and lower six teeth. Titanium screws have gained a lot of popularity in orthodontics and are being considered as an absolute source of orthodontic anchorage.So we conducted a Randomized Clinical Trial to evaluate and compare the anchorage loss anterior tooth movement and rate of retraction with direct and indirectly loaded miniscrew during en-masse retraction in subjects with bimaxillary protrusion.
