Fixed Expanders
Fixed maxillary and mandibular expanders include a broad range of appliance designs. These designs are used to correct crossbites, narrow arches and crowding. The fixed expanders utilize some mechanism of force (expansion screws, self-activating spring or wire activation) for development of the arch. These fixed designs require minimal patient compliance and provide the doctor with total control during active orthodontic treatment. Auxiliary attachments such as brackets and habit breakers can be requested for most of the expander appliances.

Slimline
The Slimline palatal screw is designed for cases needing a smaller expansion screw, offering up to 12mm of activation and more tongue space for improved patient comfort.
Memory Screw RPE
The Memory Screw Expander gives clinicians full control.After 4–5 turns, the built-in NiTi coil springs activate, providing light, continuous forces for biocompatible arch development. It can be used in both fixed and removable appliance designs.
Super Screw
The Super Screw expander provides larger arch development with a smaller screw option, available in 12mm or 16mm sizes. A special adjustment wrench is included with each appliance.
Fixed Fan Gear
The fixed fan gear appliance is the appliance of choice when presented with a tapered maxillary arch and a fixed appliance is required. The screw provides 9mm of activation.
Snap-Fit RPE
The .036 contoured buccal-lingual wire eliminates path of insertion problems. Composite is used to lock in the appliance.
MARPE W/ 3D Metal Printed Bands
Or “Micro-Implant Assisted Rapid Palatal Expander” achieves skeletal expansion in adults, non-surgical expansion in high-angle cases and helps reduce airway obstruction.
Bondable RPE
Acrylic onlays or pads are placed over the posterior teeth and then bonded in place.
NiTi-Expander
This pre-programmed, thermally activated appliance comes in various sizes for a range of expansions. Anchored by horizontal sheaths on molar bands, it’s ideal for mild-to-moderate expansion or distal rotation of 1st molars.
Quad-Helix
This appliance allows for the development of the maxillary arch by utilizing active helical springs.The springs can be activated to provide overall arch form improvement, or to address either anterior or posterior expansion needs. The design of the appliance also allows for improvement of molar rotation.
Haas
This fixed design is both tissue and tooth-borne to provide orthopedic and orthodontic changes.
Spring Jet I
Achieve slow arch expansion with controlled continuous NiTi spring force (No patient compliance required). Substitute for screw or pre-set wire expanders. Provides reliable results with minimal tipping and no patient compliance.
Spring Jet II
Achieve slow arch expansion with controlled continuous NiTi spring force (No patient compliance required). Substitute for screw or pre-set wire expanders. Provides reliable results with minimal tipping and no patient compliance.
Slimline
This fixed expander improves the lower archform with an expansion screw along with extensions to engage the lingual surface of posterior teeth, as well as primary or permanent canines.
E-Arch
Typically a lower appliance designed to upright lingually inclined posterior teeth. This NiTi spring loaded appliance is a very effective and popular choice due to its streamlined design. When the desired lateral development is achieved, the spring can be deactivated by adding composite.
Williams
The most popular of our lower uprighting appliances. This appliance uses a mini screw capable of 10mm of activation. The design incorporates an .018 NiTi archwire that freely slides labially to apply pressure to the lingual of the lower incisors in order to improve alignment as archform improvement occurs.
