Exploring the potential of segmental T-loop in two different clinical situations

This report describes the successful orthodontic treatment of two cases of highly placed canine with different clinical situations using segmental T-loop. The objective of this study was to evaluate the modification in T- loop on differently angulated canine. Orthodontic treatment of highly placed canine is justified as its aberrant position may damage the roots of adjacent teeth. In addition to it, functional occlusion and esthetic balance are achieved after orthodontic treatment. Malocclusion with severe crowding is difficult to treat without extraction as it compromises the patient's profile. Cases were managed with extraction of both maxillary and mandibular first premolars followed by Canine retraction with 0.017x0.025″ TMA wire segmented T-loop spring using 0.022″x0.028″(Edgewise appliance). Different moments were applied for canine retraction at different axial inclinations. After treatment, satisfactory improvements in facial profile and lip competency with normal overjet and overbite without marked gingival recession and anchorage loss were observed.
