The Rapid Palatal Expander is a dependable appliance for arch development. Specialty Appliances supplies all types of expansion screws in a wide range of sizes from 7 to 13 mm of expansion. The standard design has .040-inch lingual support bars placed from the bicuspids to the first molars. All expanders are custom built to meet the doctor's design specifications. [ View More Info ]

Specialty Appliances worked with two major manufacturers to design our Mini-Palex Expander. This screw is half the size of traditional screws, while still providing 8 to 12 mm of expansion. Patient comfort, speech and swallow patterns are greatly improved with the Mini-Palex's compact design. The first molars are typically used for anchorage, and .040-inch support arms extend to the first bicuspids. [ View More Info ]

The Exspider is activated in the anterior segment and hinged in the molar area. The appliance is usually anchored to first molars bands and is ideal for the patient with enough molar width and a tapered arch. It can also be used in some cleft palate patients with sufficient room for the screw. The screw is capable of 9-millimeter expansion. [ View More Info ]

A 12-millimeter reduced body expansion screw is soldered to bands on the first molars. The screw has a .059-inch lingual support wire, giving added support and durability for lower arch development. Rests are generally soldered from the expansion screw to the first bicuspids. [ View More Info ]

The Dischinger Crown Expander uses crowns on the first molars for anchorage. The crowns supply anchorage and slightly open the bite to help expansion. The 12-millimeter Mini Palex is standard activation screw. The crowns can be placed on the deciduous second molars if the first molars are not erupted. [ View More Info ]

The JI Williams uses tubing on the lingual surface of the lower posterior teeth. A .016-inch round NiTi wire is placed in the tubing to keep the lower anterior teeth rounded and inclined. An 8-millimeter expansion screw is soldered to the tubing at the first bicuspid area. Rests are then soldered from the tubing to the second bicuspids or second deciduous molars. [ View More Info ]

The DeLuke Bonded Rapid Palatal Expander can be made on permanent or mixed dentition. A 12-millimeter screw is typically used for maximum expansion. This unique patented design allows for easy delivery and removal. The wire framework is on the lingual only, and it utilizes a 3 mm pressure-formed acrylic occlusal surface. This allows for easy flex removal at the end of treatment. [ View More Info ]

The Haas design incorporates palatal acrylic on each side of the upper vault with a 13.5-millimeter expansion screw soldered to bands on the first molars, evenly exerting positive pressure on the palatal tissue and teeth. A 9-millimeter screw is utilized for a constricted arch. [ View More Info ]

The Full Palate Bonded Expander uses acrylic bonded to the first and second bicuspids and the first molars for anchorage. The acrylic extends across the palate area for bodily expansion. A 12 millimeter screw is used for maximum expansion. To aid in the removal of the appliance, debonding loops and/or debonding screws may be added. [ View More Info ]

The Fixed Quad Helix is attached to the first molars on either the upper or lower arch. The .036-inch stainless steel wire is contoured to the arch with four helical loops to help stimulate expansion. The sweep arms are contoured to the gingival of the bicuspids and cuspids. The lingual extensions can be extended to the anterior teeth if desired. [ View More Info ]

The E-Arch was originally designed by Dr. Angle. The E-Arch is one of the oldest designs for arch development still in use today. The appliance uses a pin and tube in the anterior region of the arch. An open coil spring is added for activation of the pin and tube. Once the appliance is inserted in the mouth, activation begans immediately. [ View More Info ]

The "W" arch or Porter arch uses a 0.36-inch stainless steel wire for expansion. The wire is soldered to bands on the upper first molars. The appliance can be constructed as a fixed removable that slides into sheaths on the upper first molar bands. Unilateral expansion can be achieved with proper activation. [ View More Info ]

The Pendulum has a Nance button and occlusal rests on the first and second premolars for anchorage. The springs are preactivated in the laboratory for easier insertion by the clinician. If the second molars are fully erupted, it is recommended that these be distalized first to achieve maximum efficiency in molar distalization. [ View More Info ]

The Pendex is like the Pendulum apart from an expansion screw used for transverse expansion and molar distalization. This results in greater overall arch development with the appliance. If the second molars are fully erupted, it is recommended that these be distalized first to achieve maximum efficiency in molar distalization. [ View More Info ]

The T-Rex is a modification of the Pendex that includes a .032-inch stainless steel T-Rex wires soldered to the mesial-lingual of the first molar bands. The appliance is inserted as a unit and gives greater expansion of the molars during treatment. The springs are pre-activated for easier insertion. [ View More Info ]

The PHD appliance is offered as an alternative to the Pendex. This appliance utilizes an eight-millimeter expansion screw with sheaths laser welded to it, allowing the clinician to reactivate the appliance during treatment for additional distalization. The expansion phase is completed prior to starting the distalization phase. Rests or bands are utilized for additional anchorage. [ View More Info ]

The MDA appliance offers a hygienic alternative to the Pendex. The appliance utilizes a twelve-millimeter expansion screw with sheaths laser welded to it. This allows the clinician to reactivate the appliance during treatment for additional distalization. The expansion phase is completed prior to starting the distalization phase. Rest or bands are utilized for additional anchorage. [ View More Info ]

The Rapid Molar Distalizer (RMD) offers predictable distalization with little to no tipping. Mini expansion screws are activated twice a week, applying a unique push/relax force sequence that delivers true bodily movement. RMD's low-buccal profile provides greater patient comfort with no tongue interference while anchorage is achieved with an oversized Nance button on the anterior of the palate. [ View More Info ]

The Distal Jet is a proven distalization appliance that can be used bilaterally or unilaterally on the upper arch. Adjustable coil springs are used to control the desired activation and can be changed out during treatment for additional molar movement. An anterior Nance provides anchorage while the molars are distalized. Second bicuspids will tend to travel down the alveolar process as molars distalize. Traverse expansion can be incorporated into the appliance upon request. [ View More Info ]

The Horseshoe Jet offers similar features to the Distal Jet. Patient comfort is improved with the Horseshoe Jet's streamlined design. The pure skeletal anchorage is achieved with two anterior TADs, which eliminates dental and palatal vault support and any attendant anchorage loss. This design still benefits from forces applied closer to the center of resistance of the molars. Once the activation is complete, the appliance can be locked and used as a Nance holding appliance.

Specialty fits bands or crowns with our "indirect" service on your working model at a high degree of accuracy, taking into consideration the anatomy of each tooth plus the path of insertion of the entire appliance. Using this service saves your office an extra appointment by eliminating the band fitting.

We have developed a unique software process on digital cases that isolates the target tooth receiving the band or crown. We are then able to digitally check each crown/band back on the original scan. The next step is to seat the crown/band on the printed model to double check accuracy.

Any Specialty expansion or distalizing appliance can be fabricated using our ROC crowns. As part of our lab process, the bottoms of the ROC crowns are "crimped" to provide mechanical retention in the mouth - yet another feature that sets Specialty Appliances apart from competitors.
