GUMMETAL wire enables efficient "en bloc" tooth movement (moving a block of teeth together) by utilizing a titanium-based alloy with extremely low Young’s modulus and high flexibility. This technique allows for gentle, constant forces that achieve 3D control of tooth position, reduced treatment time, and improved patient comfort compared to conventional orthodontic materials. Key Concepts of En Bloc Movement with GUMMETAL Wire: Optimal Force Delivery: GUMMETAL, a "new-age" beta-titanium alloy, acts like rubber in its ability to deform, providing nearly optimal, gentle, and continuous forces that are ideal for moving teeth. Three-Dimensional Control: The wire allows for precise 3D management of teeth, including vertical control and managing complex malocclusions (such as open bites, Class II/III, and lateral deviations) from the early stages of treatment. Simple & Fast Treatment: The technique uses simpler appliances and fewer wire changes, resulting in faster treatment times. Superior Material Properties: Unlike NiTi, GUMMETAL is super-elastic without stress-induced martensitic transformation, has no work-hardening, and is biocompatible (free of nickel, chrome, and vanadium). "Bone-Bending" Technique: The force system works by effectively transmitting force to the surrounding bone, causing it to bend along with the tooth and periodontal ligament (PDL).
