Expansion Appliances

* For an enlarged photo, go to the gallery at the bottom of the page.

3-Way Expander

A removable expansion appliance that is used to gain space through anterior advancement and midline arch expansion.


3-Way Sagittal

[Not Pictured] A removable expansion appliance that is used to gain space through anterior advancement and when additional arch width is necessary, the midline screw is activated.


Lower Schwartz

A removable appliance that is used for transverse expansion, featuring a midline screw and your preference of clasping. Hawley bow is not necessary. Our standard lower Schwartz includes two sets of ball clasps, a midline expansion screw and no Hawley labial bow.


Banded rapid palatal expander (rpe)

This appliance is banded on the 1st primary molars and can also include a band or occlusal rest for the 1st bicuspids or premolars. The expander provides midline expansion from 11mm up to 13mm. 


LEAF SPRING RPE W/ MEMORY SPRING

This 6mm/10mm screw is first activated by lab and then by doctor. The NTI springs allow the release of calibrated and continuous forces. Additionally, there is no need for parent or patient to activate


Bonded Rapid Palatal Expander

Similar to a fixed or banded palatal expander with the exception that the acrylic negates the need for spacers and fitting of bands prior to taking the impression. A soldered acclusal rest can be added to help with unwanted eruption of chosen teeth. Debonding loops can also be added to assist in removal of the appliance.


Fan Type Banded (fixed) Rapid Expander

Used to enlarge the anterior maxillary sector by keeping the molar expansion almost unmoved.


Banded Palatal Expander with NITI coil springs

To expand the midline and distalize molars without tipping, a soldered wire can be attached to allow for expansion before distalizing.


Pendulum

To distalize and the rotation of maxillary first molars; uses .032 TMA wire springs with, .036 lingual sheaths to deliver continuous force.


T Rex

Used to distalize and the rotation of the maxillary first molars. T-Rex differs from the pendulum as it is also used to expand the palate. An optional wire can be soldered to the molar band and attached to the acrylic, then cut/removed after expansion is complete.  

Uses .032 TMA wire springs with .036 lingual sheaths to deliver continuous force.


W Arch

The W Arch is similar to the Quad Helix but without the helicoils.


Quad Helix

The same as the W arch but has four helixes and is used to correct unilateral or bilateral cross bites, expand posterior segments and help align crowded teeth.


Williams Expander

This appliance is used in mixed dentition with crowed lower incisors. This is a very successful appliance. Shown with sweeping lingual springs.
