Eliminating the need for patient compliance and placing treatment outcome under the control of orthodontist was the aim of developing such appliances.With fixed functional appliances, the treatment duration was reduced to around 6 months. Beside this faster result, it became possible to use the advantage of growth modification treatment in those unfortunate patients who were near the completion of growth and were unable to take treatment during early mixed dentition period .FORSUS FRD is an innovative a three telescopic hybrid fixed functional appliance with a coil spring in its exterior part allowing forwad movement of the mandible in cases with positive VTO.
