Segmented arch technique for the correction of crowding in Angle s Class I malocclusion – A case report

A 13year old male patient presented with buccally erupted maxillary and mandibular canines, upper and lower anterior proclination, and Class I molar relationship. First premolar extraction with maximum anchorage protocol was planned to correct the crowding. Segmental arch mechanics with T-loop (0.017 × 0.025" TMA) were used to correct the buccally erupted canines. At the end of treatment patient’s soft tissue profile and smile improved significantly. Crowding and proclination of maxillary and mandibular arch were corrected and class I molar relationship was maintained.
