Hyrax- RPE

An all-metal expansion appliance typically providing sutural separation of 11mm within a very short period of wear. Up to 13mm is possible. Appliance screw is activated from front to back and each activation produces approximately .2mm of lateral expansion.

Our standard design is a two-banded style. This aids in cases with a difficult path of insertion or missing teeth. A four-banded version is available when a more rigid appliance is desired and the path of insertion is not a concern.

Optional Screws:

• Fan-Type RPE Screws. This screw option is ideal for cleft palate patients and uses a
  9mm fan-type expansion screw to symmetrically expand anteriors laterally with minimal posterior tooth movement.
• Also available with an 8 or 9mm screw set in a Haas-style acrylic for both tissue and bone anchorage. The screw is activated from front to back.
• Compact RPE Screw. This 12mm compact expansion screw increases tongue space, reduces tissue impingement, allows easier access for hygiene, and Increased patient comfort.
• Super Screw is available in 16mm and 18mm. This uniquely designed RPE screw activates from the front of the mouth with a hex wrench. The appearance of threads indicates expansion limit has been reached.
