Leaf Expander^®

50% reduction in follow-up visits*
Validated activation protocol

The original model is validated by thousands of cases and several scientific articles.

The 450g and 900g models are to be used in growing patients to achieve slow and painless orthopaedic expansion.

The 900g version is indicated in adult patients to achieve dentoalveolar expansion.

Leaf Self Expander^®

No home or in-office activation
No risk of overtreatment

The Leaf Expander^® that does not require in-office re-activation.

The indications and clinical effects are the same as the original model.

In growing patients, a slow and painless orthopaedic expansion can be achieved using either the 450g or 900g models, while in adult patients the 900g version is suggested to achieve dentoalveolar expansion.

Leaf Self Expander Anatomical^®

Thanks to the reduced dimensions and the orthogonal position of the arms, it allows space-saving devices to be made for very young patients, even with full deciduous dentition.

The force released by the springs is 600g, which is ideal for achieving the expansion of the arch at both alveolar and suture level.

Mini Leaf Self Expander CAD-CAM^®

The flat shape of the bodies and the small size make these expanders suitable for the digital design of a distalizer that utilizes the principles of the Leaf expanders by constantly releasing a 600g force. The 3DLeone Designer software provides the anchorage with a Nance button and the version with TADs for bone anchorage.
