Interceptive therapy is required for definite closure of midline diastema. Stability of result requires bodily approximation of the incisors. Many well designed sectional springs have been reported in literature for the correction of midline diastema. In this article a case of midline diastema treated with ‘Trihelix spring’ is selected. This innovative spring is fabricated with A J Wilcock stainless steel, 0.014’’ special plus wire and contains three helices. This ‘Trihelix spring’ is a simple, effective, aesthetic and biologically compatible device with excellent root control for the treatment of midline diastema.
