Neo-Bertoni type A and Neo-Bertoni type B

Anatomically angulated three-dimensional screws. Adapted to the geometry of the average palate to save as much space as possible when fitting in the appliance. Restriction in the tongue cavity caused by the appliance is thereby reduced to a minimum; more comfortable for the patient.

Special expansion screw for palatal expansion.

The minimal dimensions of the hyrax^® expansion screw are ideal for small palates. Many innovative construction details make their use even easier, safer and more effective.

hyrax^® click: RPE screw with feature to prevent unwanted reversing.

Tried-and-tested technique for the efficient and safe expansion of the palate with additional feature to prevent unwanted reversing.

hyrax^® neo: Special expansion screw for palatal expansion

The hyrax^® neo stands out with its new, minimalistic body design and retention legs that are parallel to the palate suture. This design makes the hyrax^® neo the ideal partner for working with TAD systems, such as tomas^®.

Perfect in form.

The skeletal construction enables the screws to have the smallest possible dimensions, yet achieve the largest possible expansion. The integrated expansion stop prevents the screws from falling apart.

Perfect in function.

The friction on the thread of each screw is so exact that they are guaranteed to open evenly. The unique click versions are secured against unwanted reversing, thereby preventing the screws used for the fixed appliance technique from turning back.

Perfect in design.

The high-precision screws have a stable construction and are of high quality. They can therefore be fixed securely in the acrylic.
