Fränkel II

Used in growing patients exhibiting Class I or Class II, the FränkelII utilizes buccal shields and lip pads to restrict undesirable muscle forces while accomplishing transverse and vertical development.

The designs allows for additional advancement of the mandibular portion by segmenting the buccal shields or optional expansion screws can be added for this purpose thus eliminating the need for an additional lab procedure in the future. The lab requires maxillary and mandibular models and a bite registration reflecting the desired position of the mandible with 3mm of posterior opening.
