Mathieu orthodontic pliers are positive locking pliers intended for holding, placing, and tying ligatures and elastics. They also can be used for grasping and guiding a needle when suturing. Styles of Mathieu orthodontic pliers include standard, narrow, hook and notched. The tips or beaks of Mathieu orthodontic pliers may vary in size for specific size ligatures and elastics, and feature extra fine serrations for superior grip and holding of ligatures and elastics without tearing. Be sure the pliers are constructed from high-grade stainless steel for durability, strength and corrosion resistance.
