Evaluation of treatment efficacy of splint-supported Forsus Fatigue Resistant Device vs Twin block in skeletal Class II growing subjects. A randomised clinical trial

Subjects found suitable in the pre determined inclusion criteria for the study shall be explained the scope of the study and a written consent shall be obtained. Pre-treatment records (T1) in the form of photographs (extraoral & intraoral), radiographs i.e., OPG, Lateral cephalogram, and dental models formaxillary and mandibular arch shall be recorded. For splint-supported FFRD group a customized splint will be fabricated on the mandibular arch and FFRD shall be installed using upper molar band and splint in lower canine region. Standard Twin block shall be given to another group. On achieving satisfactory profile improvement /correction in overjet /molar relation, post functional treatment records (T2) in the form of photographs (extraoral & intraoral), radiographs i.e., OPG, Lateral cephalogram, dental models formaxillary and mandibular arch shall be obtained.  Pre-treatment and post functional treatment lateral Cephalogram shall be analyzed using various cephalometric values to ascertain the corrections achieved. Corrections achieved will be quantified and will be grouped as skeletal, dental & soft tissue changes. In addition, the treatment duration for the study groups shall be recorded, the patient comfort & operator convenience along with frequency of breakage of appliance (if any) shall be noted.
