Active Appliances

3 Screw Combination

The Combination appliance provides lateral and sagittal arch development to relieve crowding. This 3 screw appliance can be made with or without occlusal acrylic, and combines 1 transverse and 2 sagittal expanders.

3D Screw Expansion

Offers 3-way expansion of the maxillary dental arch. The screw mechanism both widens posteriors and proclines anteriors for Y-shaped arch development.

3D Screw Expansion Appliance

Bioblock Appliance

A Bioblock is used to expand the upper arch and posture the lower jaw forward. This appliance utilizes 1 expansion screw, cross-over wires, and 30 degree posterior inclined planes to develop the lower arch.

Crossbite Screw

The removable acrylic appliance applies forces to rotate and move anterior teeth forward over the bite. An expansion screw with posterior occlusal acrylic is activated to labialize teeth and jump crossbite.

Crossbite Spring

This crossbite appliance acts to move teeth labially out of crossbite. The removable appliance design uses posterior bite blocks and finger springs to apply pressure for labial movement over crossbite.

Fan Expander

This appliance is designed to treat a v-shaped dental arch by rounding out the anterior dentition. It consists of a hinge and a pivoting expansion screw for sectional widening of the maxillary arch.

Sagittal Appliance Lower

The Sagittal is utilized to achieve anterior development and/or distalization of the posterior segments. Bilateral expansion screws are activated to expand in an anterior/posterior direction.These appliances can be made for upper or lower arches.

Sagittal Appliance Upper

The Sagittal is utilized to achieve anterior development and/or distalization of the posterior segments. Bilateral expansion screws are activated to expand in an anterior/posterior direction.These appliances can be made for upper or lower arches.

Sagittal Appliance Upper

This upper expander is used for posterior space regaining when arch length is lost due to premature loss of dentition. A single unilateral expansion screw applies forces to move teeth distally.

Schwarz Appliance Lower

This expansion appliance widens the mandibular arch and provides arch development/uprighting in the lower arch. The single expansion screw and cross-over wires act to expand dentition and align anterior teeth.

Schwarz Appliance Upper

This expansion appliance widens the maxillary arch and provides arch development/uprighting in the lower arch. The single expansion screw and cross-over wires act to expand dentition and align anterior teeth.

Split Plate Upper

Designed to widen the maxillary dental arch, midline expansion screws are activated to increase arch width, and relieve crowding and posterior crossbites.

Spring Retainer Upper

The upper Spring Retainer is designed to correct minor rotations of anterior teeth. This removable, self-activating appliance also utilizes a treatment set-up for anterior alignment.

Transverse Lower

The lower Transverse appliance is used for lateral development of the mandibular dental arch. A single midline screw acts to upright posterior segments and widen the mandibular arch.

Upper Expander

Designed to widen the maxillary dental arch, midline screw is activated to increase arch width, and relieve crowding and posterior crossbites.
