In a young woman, aged 16 years, with upper anterior spacing and mesiopalatal rotation of upper central incisors, the right and left mandibular first molar extraction spaces were closed by protraction of the second and third molars without reciprocal retraction of the incisors and the premolars. The amounts of protraction for the second molars were 8 mm on the right side and 6 mm on the left side. Initial uprighting of lower second molars were done by T-loop on both sides. A titanium miniscrew was placed in the buccal alveolar bone between the first and second premolars on right side to provide direct anchorage for absolute protraction forces. On the left side uprighting and protraction was done simultaneously with the use of T-loop as uneven and less space was present on left side as compared to the right side. Careful biomechanical consideration was used to prevent tipping, rotation of posterior teeth. The treatment time was 20 months. Ideal overjet and overbite with good posterior occlusion was achieved.
