The aim of this study: is to evaluate the maxillary molars distalization by nickel titanium open coil springs and miniscrew supported anchorage followed by maxillary posterior teeth alignment. Ten patients (seven girls and 3 boys: 11 to 14 years old) with dental Class II relation were selected for this study. All patients were treated with compressed Nickel Titanium open coil springs and a bone anchored transpalatal arch cemented on the maxillary first premolars. Bone anchorage was provided by two paramedian miniscrews inserted in the anterior part of the palate. Distalization was completed in an average of 4.6 months. The maxillary first molars were distalized by 4.82 mm, distally tipped with 7.42° and extruded by 1 mm on average. The maxillary first premolars were mesially tipped by 8.11° and the maxillary central incisors were proclined by 2.20° on average. No significant skeletal effects were recorded. Immediately loaded miniscrew supported anchorage unit was successful in achieving sufficient molar distalization.
