Palatal expanders
Ragno Fan-Type Rapid Expander A0625
Widening of the anterior sector while keeping posterior expansion to a minimum — down to a 7 mm mini version.
A0625-09A0625-07
Made entirely of biomedical stainless steel, with the expanding arms laser welded to the screw body and directional arrows laser engraved on the MIM® body. The Ragno is a device for rapid expansion of the palate that allows widening of the single anterior sector of the maxillary arch while still maintaining minimum expansion in the posterior sector.
It self-deactivates when maximum expansion capacity has been reached, preventing overtreatment. The difference between the two models is the geometric shape of the front part: the A0625-07 is designed to be placed as high as possible in the palate vault, ensuring the minimum bulkiness achievable — its overall size is roughly 20 to 25 % less than the 9 mm version. Developed with the cooperation of Dr. Eleonora Schellino and Prof. Remo Modica.
