Super micro screw A0890 Leone

Leone expansion screws for removable orthodontic appliances are the result of 80 years of in-depth research, design studies, and millions of clinical cases. The entire production process takes place in Italy using automated machines that operate under the constant control of electronic computers. Leone screws are made of the highest quality biomedical stainless steel; the male screw thread has tolerances of hundredths of a millimeter, with a total absence of surface roughness; the bodies and guides are manufactured with tolerances of +/- 0.01 mm, ensuring absolute stability and precision. The wide range available allows for the production of every type of removable appliance.
