Objective: To present a new, simple and economical appliance for bringing a palatally impacted canine into the oral cavity. Material and methods-The basic appliance design incorporates Adams clasps, usually on both first molars, a posterior bite block and bow of 0.8 mm wire with a stainless steel tubing (to increase the strength) with a helix at the open end, to wear an elastic from attachment on the tooth. Results: Treatment resulted in the eruption of left canine till the occlusal level in the oral cavity through the attached mucosa and simultaneous correction of rotated right canine, with coinciding midlines and no mandibular shift. Conclusion: The simple upper removable appliance can be used as an excellent method of treating palatally impacted canines.
