RPE with habit crib

Hyrax RPE with Tongue Crib

The RPE is typically used in phase I treatment to widen the arch, either prior or during fixed treatment. Along with the RPE, we can add a tongue crib to aid in thumb and tongue thrusting habits. Our expanders come in 7 or 11 mm screws and vary in activation depending on the style. Our standard expander uses the 11mm Leone expander and has welded lingual wires expanding to the premolars or cuspids. It is constructed entirely of biomedical stainless steel, and the housing is completely smooth with no rough areas to aid in hygiene. With each expansion appliance, we provide a custom swivel key that has an integrated activation recording tool directly on the handle. Tip: If you find an expander is hard to turn, run under warm water to loosen the threads.

PLEASE SEND OPPOSING ARCH TO OCCLUDE FOR PROPER POSITION.

Description

Treatment & Care

The typical rate of activation is one (1) per day. Each RPE requires four (4) activations per 1mm. It is Not uncommon to double up with one turn in the morning and one in the evening. Going too fast may damage periodontal membrane or roots of the teeth. Going too slow may result in producing more dentoalveolar change and less sutural split than normally desired.

This appliance should be cleaned every day with toothpaste and a soft toothbrush, morning and night. Encourage the patient to give sufficient time to clean thoroughly around the appliance, gums, teeth, and bands to maintain proper hygiene and prevent inflammation. 3 minutes is recommended.
