G4™ Nickel Titanium

What is G4™ Nickel Titanium?

G4™ Nickel Titanium Wire is the result of years of research and development by G&H. G4™ NiTi is made possible by the vast experience and expertise that G&H has developed in working and controlling Nickel Titanium. G4™ NiTi is superior due to refinements and advancements by by G&H in several key areas:

Material Science
The G4™ Nickel Titanium alloy is unique. G4™ has been exclusively formulated to coordinate with G&H manufacturing processes to yield consistent specific force, memory and elasticity values.

Precision Manufacturing Processes
Nickel Titanium is an alloy which is complex to process and form. Very slight variations in a multitude of factors during manufacturing can alter the clinical performance of NiTi wires. The G4™ manufacturing processes some invented, some developed and others refined by G&H make G4™ NiTi distinct from all other NiTi archwires used in Orthodontics.

Scientific Testing Protocols
Only scientific testing of a NiTi wire can determine its actual working characteristics. G4™ NiTi archwires undergo intense scientific testing during and after the manufacturing process: Each production lot of G4™ wire undergoes 14 separate quality tests during manufacturing. Every G4™ wire then undergoes a 28-point 100% final inspection before packaging. All G4™ wires successfully pass all testing so that performance characteristics can be guaranteed.

Recovery Forces of G4™ Nickel Titanium

The Clinical Significance of G4™ Nickel Titanium
The clinically significant improvements to G4™ wire provide lower initial load forces and increased residual forces as full shape recovery progresses. (Fig. A)

Lower Load Forces of Engagement
Easier wire deflection and delivery to bracket, less stress on bonds and increased patient comfort.

Higher Residual forces of recovery
Full shape recovery - complete unraveling and archform development by staying active to the end.
