Functional Appliances


Activator

A removable appliance for the treatment of a Class II malocclusion to be used in conjunction with headgear duration of wear 12 to 14 hrs

Bionator I (to Open)

A removable appliance for the treatment of a Class II malocclusion with a deep bite where eruption of the posterior teeth is desired in addition to orthopedic change in growing patients. The mandible is held in the desired advanced position. An incisal cap is utilized on the mandibular anteriors with an opposing bite surface for the maxillary anteriors to prevent any undesirable eruption. The posterior acrylic is trimmed to guide eruption of the posterior teeth. The lab requires maxillary and mandibular models and a construction bite reflecting an edge to edge relationship in the anterior teeth with a 3 mm anterior opening

Bionator II (to Close)

A removable appliance for the treatment of a Class II malocclusion with an open bite where the eruption of the anterior teeth is desired in addition to orthopedic change in growing patients. The mandible is held in the desired advanced position. A posterior bite surface is utilized to prevent the eruption of the posterior teeth while the acrylic in the anterior region is relieved to allow for free eruption of the anterior teeth. The lab requires maxillary and mandibular models and a construction bite reflecting an edge to edge relationship with a 3 mm posterior opening.

Fränkel II

Used in growing patients exhibiting Class I or Class II, the Fränkel II 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.
