The AFR Mini-REG is an anterior functional registration device to trace the movement of the mandible. Like any conventional JIG splint, the AFR Mini-Reg is designed to temporarily deprogram the neuromuscular system. Like any other JIG splint a neuromuscular relaxation can be achieved. Interfering occlusal influences are prevented. The maximum movement of the mandible is recorded in the form of an arrow angle, also known as the Gothic arch tracing.
