Background: Tooth movement in orthodontics depends upon the magnitude and duration of applied force, alveolar bone density and morphology, periodontal ligament density and width, cellularity of the attachment apparatus and root size and form. The present study was conducted to assess the clinical efficiency of newly introduced Hycon device in orthodontic extraction space closure. Material & Methods: A total of 20 patients who undergoing orthodontic treatment requiring bilateral extraction (first premolar) in the same arch to be selected for treatment. A split mouth technique was used where one side included the Hycon device supported extraction space closure (group I) and on the contralateral side space closure was done using NiTi closed coil springs (group II). Result: The results of the study showed that the Hycon device is an efficitive alternate device for the extraction space closure and faster rate of space closure than the NiTi closed coil springs when compared for a duration of 90 days
