Orthodontic Expanders and Facemasks for Transverse and Skeletal Correction
Orthodontic expanders and facemasks supply the appliances used to widen the dental arch and apply orthopedic force to the jaws. The category stocks fixed and removable expanders, protraction facemasks and headgear, serving orthodontic practices, group dental offices, dental service organizations and dental schools treating transverse and skeletal cases.
Expansion and Orthopedic Appliances Stocked
- Rapid palatal expander screws - Hyrax and Haas-type expansion screws in graduated ranges for banded and bonded rapid maxillary expansion appliances.
- Quad-helix and W-arch appliances - Fixed slow-expansion appliances and the preformed wire blanks and attachments used to fabricate them.
- Removable expansion appliances - Acrylic expansion plates with midline screws for slow arch development.
- Protraction facemasks - Delaire-type reverse-pull facemasks with adjustable forehead and chin pads and support framework for maxillary protraction.
- Headgear and force components - Cervical, high-pull and combination headgear, facebows, and the elastics and springs that supply orthopedic force.
Expansion Appliance Types
| Appliance | Force Type | Fixation |
|---|---|---|
| Hyrax RPE | Rapid transverse expansion | Banded or bonded, tooth-borne |
| Quad-helix | Slow transverse expansion | Fixed, band-anchored |
| Removable expansion plate | Slow expansion | Removable, acrylic-borne |
| Protraction facemask | Maxillary protraction | Extraoral, forehead and chin support |
Fixed, Removable and Extraoral Appliances
Expansion and orthopedic appliances divide into fixed intraoral appliances such as hyrax expanders and quad-helix, removable acrylic expansion plates, and extraoral components such as protraction facemasks and headgear. Fixed expanders anchor to banded molars and drive transverse change through an activation screw, while facemasks and headgear apply extraoral orthopedic force through pads and framework. The category stocks the screws, wire blanks, framework and force components used to build and deliver these appliances.
Expansion and orthopedic appliances are a lower-volume, higher-value segment of orthodontic supply than chairside consumables, and practices stock expansion screws, facemask framework and headgear against their interceptive and orthopedic caseload. Consolidating these components with the rest of an orthodontic order simplifies procurement. Order at the best Wholesale Prices with MAP Medical.
Frequently Asked Questions
What is the difference between a hyrax and a quad-helix expander?
A hyrax is a rapid palatal expander driven by a midline jackscrew that is activated in small increments to produce fast transverse expansion, anchored to banded or bonded posterior teeth. A quad-helix is a fixed appliance made from spring wire with helical loops that delivers slower, lighter expansion force. Both are stocked, along with the screws, wire and bands used to build them.
What is a protraction facemask used for?
A protraction facemask, also called a reverse-pull or Delaire facemask, is an extraoral appliance with forehead and chin support that applies forward orthopedic force to the maxilla, typically in growing patients with maxillary retrusion. It is stocked with adjustable pads, support framework and the elastics that supply the protraction force.
Are expansion screws stocked in different sizes?
Yes. Hyrax and Haas-type expansion screws are stocked in graduated ranges by expansion capacity and body size, for banded and bonded appliances and for different arch dimensions. Removable expansion plate screws are also stocked. Screw selection for a case is a clinical decision made by the treating orthodontist.
Can orthodontic practices order expanders and facemasks in bulk?
Yes. Expansion screws, quad-helix blanks, facemasks and headgear are stocked for orthodontic practices, group dental offices, dental service organizations, dental schools and licensed distributors, with case and bulk quantities on high-turn components such as expansion screws. Contact our procurement team for tiered case pricing and standing order setup.
What expansion and orthopedic appliances should be in a formulary?
A core expansion and orthopedic formulary typically includes hyrax expansion screws in a graduated range, quad-helix wire blanks or preformed appliances, removable expansion plate screws, a stock of protraction facemasks in adjustable sizes, and cervical and high-pull headgear with facebows. MAP Medical builds consolidated appliance packages matched to a practice's interceptive and orthopedic caseload - contact our team for an assessment.
