EXPAND
rme
a range of expanders including rapid maxillary expanders as well as leaf expanders
Rapid Maxillary Expanders allow for rapid palatal expansion. activated by the patient/parent by turning the key. The key is turned creating tension stimulating bone growth and causing the separation of the mid-palatal suture.
The NiTi leaf springs are predetermined, calibrated, and provide constant force. The appliance is compressed and then once fitted into place, the clinician activates it by removing the key which allows the NiTi leaf springs to decompress and expand. Following this, the appliance is reactivated by the clinician, following the leaf expander protocol.
The Leaf Expander is a non-compliant option for palatal expansion as the appliance is only activated at appointments with the clinician. The Leaf Expander is available with either 6mm or 9mm expansion capacity and with a force of either 450g or 900g.
With the use of Leone’s innovative software, we are excited to offer 3D-printed palatal expander devices. Our technicians can design the appliance which can then be validated by the clinician using Leone Designer Viewer software. Once the design is confirmed the appliance is printed, creating a well-contoured and easy-to-fit appliance.
For standard RME cases, please send us an upper stl file or impression, band size, and design. Please note that it is recommended that a slightly larger band size is used as this allows for ease of insertion when fitting the appliance.
For 3D printed RME cases please send us an upper stl file or impression, the design will be sent to you to view on Leone Designer Viewer once complete.
Please send (for 3D Printed expanders): an upper STL file, impression, or model.
Please send (for standard, not 3D Printed expanders): an upper STL file, impression or model, the band size, and design of the appliance.
Turnaround time: 7 working days
QUADHELIX
The Quadhelix appliance is a fixed upper expansion appliance used to expand the arch, aiming to create additional room for overcrowded teeth or to correct a posterior cross-bite.
The name Quadhelix refers to the four helixes in the appliance, two in the anterior section of the wire and two in the posterior.
The Quadhelix is compressed as it is fitted, meaning the appliance is pre-loaded and does not require any activation or adjustments by the patient.
Please send: an upper stl file or impression, band size, and design of the appliance.
Turnaround time: 5 working days.
TPA
The TPA is an expansion appliance made from wire which can be used to expand the arch and rotate the molars.
Please send: an upper stl file or impression and the band size.
Turnaround time: 5 working days
