“…In vitro studies showed that Gummetal has low stiffness, low Young's modulus, and generates light forces, 7,19 meaning that its clinical performance should be comparable to NiTi. Suzuki et al 8 used niobium-titanium archwires and NiTi archwires to produce buccal tooth movement in rats, and they found no difference in terms of tooth movement between the two types of wires.…”

Objectives: The purpose of this prospective, double-blind, randomized clinical trial was to compare the clinical efficiency of nickel-titanium (NiTi) and niobium-titanium-tantalum-zirconium (TiNbTaZr) archwires during initial orthodontic alignment. Materials and Methods: All subjects (ages between 12 and 20 years) underwent nonextraction treatment using 0.022-inch brackets. All patients were randomized into two groups for initial alignment with 0.016-inch NiTi archwires (n ¼ 14), or with 0.016-inch TiNbTaZr archwires (n ¼ 14). Digital scans were taken during the course of treatment and were used to compare the improvement in Little's Irregularity Index and the changes in intercanine and intermolar widths. Results: There was approximately a 27% reduction in crowding during the first month with the use of 0.016-inch TiNbTaZr (Gummetal) wire, and an additional 25% decrease in crowding was observed during the next month. There was no significant difference between the two treatment groups in the decrease in irregularity over time (P ¼ .29). There was no significant difference between the two groups in the changes in intercanine and intermolar width (P ¼ .80). Conclusions: It can be concluded that Gummetal wires and conventional NiTi wires possess a similar ability to align teeth, and Gummetal wires have additional advantages over conventional NiTi, such as formability and use in patients with nickel allergy.

“…Proposed mechanisms of anomalous deformation behavior in multifunctional Gum Metal include reversible nanodisturbance [44], deformation twinning [45], reversible stress‐induced martensitic transformation [46], and spatially confined martensitic transformation from a BCC crystal structure to α” (orthorhombic) and δ phases [47,48]. 5.All constituent atomic elements of the alloy are biocompatible and non‐toxic [49]. 6.Compared to other titanium wires, a Gum Metal wire generates approximately half the friction between the archwire and bracket with an appropriately treated surface [39,40].…”

This literature review investigated a recently developed orthodontic wire composed of a β-titanium alloy known as "Gum Metal" and compared its properties with those of conventional wires. The attractive properties of Gum Metal include an ultra-low Young's modulus, non-linear elastic behavior, ultra-high strength, high yield strain, high ductility, and superplastic deformability without work hardening at room temperature. The unique multifunctional characteristics of this new orthodontic wire make it almost ideal for orthodontic applications. The results of this literature review indicate the strong potential use of Gum Metal wire for improving and enhancing the effectiveness of orthodontic treatment.

“…Besides, gum metal presents good electro-chemical behavior, superior anticorrosive resistance and negligible toxicity in comparison with CP-Ti [12]. Thus, the novel properties of gum metal make it potentially very promising for biomedical applications.…”
