[The functional regulator (FR II)].
The Frankel II appliance which is used in Angle Class II Division 2 cases, establish sagittal, vertical and transversal development of the jaws by keeping away the perioral muscles as in the other functional regulators. The difference between FR II and FR I appliances is the design of canine wires. After 8 months of FR II treatment of the 11 year old Class II Div. 2 patient with 5 mm. overbite, as the overbite decreased by 3 mm., the FMA angle increased and a transversal and sagittal development was established in both upper and lower jaws.
