Abstract
|
|
|
|
The functional regulator(FR) appliances act to remove the restrictive forces that prevent the normal maturation of the maxilla and mandible. FR appliances are different from other functional jaw orthopedic appliances(e.g., the twin block, bionator, and activator). has based his treatment philosophy on the concept that the capacity to regulate growth residues in the soft tissue environment, and that adequate space must be available for the proper development of the hard tissue. In class II malocclusion with mandibular retrusion, FR-II treatment is not only the change in the postural position of mandible, but also expansion of the dental arches. By balancing the neuromuscular environment, not only can severe malocclusions be treated successfully, but also the tendency toward relapse is minimized because the neural and soft tissue factors associated with the skeletal malocclusion have been addressed as well. We report cases using by FR-II that is applicated in cases of Class II malocclusion without fixed appliance, only FR-II and space supervision.
