Expansor™ series expansion screws with Muscle Thread™.
Made of 100% Swedish surgical grade stainless steel. Leone's unique Muscle Thread™ maintains a direct compressive force to suppress slipping/back-turning. This property is derived from extruding the threads with compression, resulting in a perfect fit, total surface smoothness, and maximum hardness. Guaranteed against corrosion in the oral cavity.
Choose from Leone's standard four-leg, two-leg, and fan-type expanders.
All Leone/American Tooth expansion screws may be combined for the best quantity price discount.
