 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.

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.

A removable
appliance for the treatment of a Class II malocclusion where orthopedic
change with no vertical eruption is desired in growing patients. The
mandible is held in the desired advanced position.
The incisal
cap from the Bionator I is utilized to prevent eruption of the anterior
teeth in conjunction with the posterior bite surface from the Bionator
II to prevent eruption of the posterior teeth.
The lab
requires maxillary and mandibular models and a construction bite reflecting
an edge to edge relationship and at least 3 mm of opening all around.

 A
removable appliance for the treatment of a Class II malocclusion to
be used in conjunction with headgear. Full maxillary and mandibular
indexing is provided to maximize the headgear's effectiveness.
Wire torquing
springs are placed on the maxillary incisors and a lip pad extends
from the mandibular portion to restrict undesirable muscle forces.
Headgear tubes are placed as desired, usually in the bicuspid/first
molar region.
The lab
requires maxillary and mandibular models and a bite registration reflecting
an edge to edge relationship with 8mm of posterior opening.

 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.
