“…These results are in accordance with Murakami et al [31], which reported a continuous light force delivery for GUMMETAL® compared to TMA and Resolve, both βTi-derived alloys. This plastic behavior without crystal motion dislocation occurs due to oxygen addition and proper cold working [11,12,32]. In contrast, GUMMETAL® delivered lower unloading forces than NiTi and SS when combined with CL brackets; these might be attributed to a wire-bracket interaction, mainly due to the high friction achieved by the ligatures [33].…”

“…Changing wires during orthodontic treatment increases costs and also overall treatment time; additionally, the order of which archwires alloys to employ relies solely on professional experience. The use of GUMMETAL®, a specific type of βTi, has been proposed as a new alloy for orthodontic purposes due its high elasticity, moldability, and low rigidity [11,26]; this wire seems to have the most remarkable mechanical properties described for an orthodontic wire making it suitable for use during all treatment phases [11].…”

“…A new β-titanium (βTi) alloy, named GUMMETAL®, has been suggested to display more favorable biomechanical properties than other known wire material. This multifunctional βTi alloy, developed in 2003, has a β-type, bodycentered, cubic crystal structure, composed of titanium-niobium-tantalum-zirconium (Ti-36Nb-2Ta-3Zr-0.3O) [7,11,12]. GUMMETAL® is made of biocompatible and nontoxic atomic elements, and it is claimed to possess ultra-high-strength, an ultra-low Young's modulus, high flexibility, superelasticity (without hysteresis) [11].…”

A recently developed orthodontic wire alloy known as GUMMETAL® is claimed to deliver more physiological forces to correct dental mispositioning. However, its mechanical characteristics have not been fully characterized yet. This study aimed to determine and compare the elastic properties of different wire alloys, such as nickel-titanium (NiTi), stainless steel (SS), and GUMMETAL®, and assess their unloading forces when combined with either conventional or self-ligating brackets (CL and SL) when correcting dental crowding. All wires had a 0.016″ cross-section diameter. A three-point bending test was performed to assess the maximum deflection of each wire. Then, a subsequent analysis measured the unloading force for each wire/bracket system in a dental crowding clinical simulation device. The test was carried out in a universal testing machine with a cross-speed displacement of 0.5 mm/min. Data were recorded in different ranges and statistically evaluated using two-way analysis of variance. GUMMETAL® displayed higher unloading mean forces in SL brackets (2228.78 cN) than CL brackets (1967.38 cN) for the 1.6-3.0 deflection interval (p = 0.018). Within this interval, NiTi showed higher forces when used with CL brackets (2683.06 cN) than with SL brackets (1179.66 cN) (p < 0.0001). For the CL bracket systems, SS wires showed higher forces (2125.31 cN) in the 1.0-1.6 deflection interval than the other two wire alloys (NiTi, 1541.52 cN and GUMMETAL®, 852.65 cN) (p < 0.0001). SS wires also displayed lower forces with SL brackets (1844.01 cN) than in CL brackets (2125.31 cN) (p = 0.049). Thus, only GUMMETAL® revealed to be an optimal choice for SL brackets, whereas NiTi for CL brackets.

“…This led to the introduction of orthodontic appliances that combine the esthetics with optimal performance. [123] In fixed orthodontic therapy, the introduction of esthetic orthodontic brackets partially solved the issue, but most of the orthodontic wire alloys are stainless steel, cobalt-chromium, beta-titanium, and nickel-titanium (NiTi).

Objectives: The objective of the study is to evaluate the surface roughness, nanomechancial properties the color stability of three brands of coated (rhodium, epoxy, and Teflon) nickel-titanium (NiTi) esthetic archwires. Materials and Methods: Three brands of coated (rhodium, epoxy, and Teflon) esthetic NiTi archwires and three brands of uncoated (NiTi) archwires from the same manufactures were evaluated for the surface roughness, nanomechanical properties, and color stability. The specimens with 20 mm length ( n = 5) were cut from the straight buccal segments of the coated and uncoated archwires. The specimens with 20 mm length ( n = 10) were subjected to color measurement after immersion in a coffee staining solution. The color measurement was evaluated after 7, 14, 21, and 28 days after immersion in staining solution using color eye 7000 spectrophotometer. The experimental data were analyzed using descriptive statistics, analyses of variance, and Tukey's post hoc test. Results: Epoxy (1.517 ± 0.071) and rhodium (0.297 ± 0.015) coated archwires showed the highest and lower value of surface roughness. All the intergroup comparisons showed a significant difference ( P < 0.05) in surface roughness except between rhodium and control group ( P = 0.998). There were significant differences between control and the experimental groups for both nanohardness and elastic modulus was observed. All the three NiTi-coated esthetic archwires demonstrated trace” (extremely slight change) color changes as measured by the National Bureau of Standards units after 4 weeks of immersion. Conclusion: Surface roughness of rhodium-coated archwires was almost similar to that of uncoated wires. Whereas Teflon and epoxy coated archwires showed a significant difference in surface roughness compared to uncoated archwires. Uncoated archwires showed higher nanohardness values compared to the coated archwires. Teflon-coated archwires demonstrated significantly slight color change after 4 weeks of immersion in staining solution.

“…Also, such alloys are widely used in medicine as bone-replacement prosthesis and dental implants and instruments due to the biocompatibility of titanium. [1][2][3][4] b titanium alloys show favorable strength to density ratio, combined with good ductility and attractive processing features such as deep hardenability and forging performance. [5] Nowadays, the most often applied b titanium alloys are Ti-10V-2Fe-3Al (Ti-10-2-3), developed in 1970 by Timet Company, and Ti-5Al-5Mo-5V-3Cr (Ti-5553).…”

The hot deformation behavior of Ti-10V-2Fe-3Al alloy obtained by the powder metallurgy (PM) method was investigated. Material for the research was produced by blending of elemental powders followed by uniaxial hot pressing. Thermomechanical tests of Ti-10V-2Fe-3Al compacts were carried out to determinate the stress-strain relationships at the temperature range of 800°C to 1000°C and strain rate between 0.01 and 10 s À1. Based on the dynamic material model (DMM) theory, processing maps at constant strain value were developed using data obtained from hot compression tests. The processing maps were elaborated for the final strain value, which was 0.9, and with flow instability criterion domains applied to it. Two critical regions associated with the flow behavior of the investigated material were revealed. Microstructural changes during hot deformation at various temperatures and strain rates were discussed. The correlation between calculated efficiency of power dissipation, flow instability criterion, and microstructure evolution was determined. The presence of defects was confirmed in regions predicted by the instability maps. The microstructure of the investigated alloy, corresponding to the high efficiency of power dissipation characterized by the occurrence of dynamic recrystallization (DRX) phenomena, was also shown. Additionally, average hardness values in relation to variable process parameters were designated. Based on the conducted studies and analysis, processing windows for Ti-10V-2Fe-3Al alloy compacts were proposed.
