Abstract


INTRODUCTION
Since the development of the twin block appliance by W.J. Clark in
19821 for the treatment of Class II malocclusions with mandibular
skeletal retrusion, it has been the most popular and successful
functional appliance for correction of sagittal skeletal discrepancy.
Twin block has been described by the patients as the most successful and
comfortable of all functional appliances2. In cases of growing patients
with skeletal Class II malocclusion with mandible retrusion, the Class II
Twin-block appliance can be used to stimulate and enhance mandibular
growth. This appliance consists of upper and lower removable plates1.
Since the success with removable appliances largely depends on patient's
compliance, using a more tolerable appliance can increase the chances of
a favourable outcome3. In comparison with removable functional
monoblocks, the appliance's separate plates and a less bulky appearance
improve patient compliance and increase the time for which the subjects
wear the appliance.
