A beta titanium alloy was evaluated for use in orthodontic appliances. Standard mechanical tests and a specially designed spring test were used. Two particular thermo-mechanical treatments resulted in titanium springs with 1.8 times the extension of comparable stainless steel springs, and a 2.2 fold reduction in force per unit displacement. 
Beta titanium: a new orthodontic alloy.
The beta titanium wire has a unique balance of low stiffness, high springback, formability, and weldability which indicates its use in a wide range of clinical applications.
The Influence of Drawing Parameters on the Mechanical Properties of Two Beta-titanium Alloys
The total cold reduction and reduction per pass used during the drawing of fine wires affected the mechanical properties of two beta-titanium alloys, which resulted in wires appropriate for orthodontic application.
An Overview of Orthodontic Wires
Orthodontic wires are components of fixed appliances used to carry out the necessary tooth movements as part of orthodontic treatment. A variety of materials like metals, alloys, polymers and
Mechanical Behavior of Orthodontic TMA Wires
Titanium based alloys are recently gaining increased popularity in orthodontic treatment. Unlike the classic materials, these intelligent materials have physical and mechanical characteristics which
Biomaterials used in orthodontics: brackets, archwires, and clear aligners
Abstract The rapid advancements observed in the field of orthodontics have been mostly due to the improvement in the field of material sciences. The better understanding of biologic problems and

The Clinical Relevance Of Orthodontic Archwire Properties: A Review.
Archwires are the active components of a fixed appliance through which forces are generated and consequently tooth movement is achieved. Recent advances in orthodontic wire alloys have resulted in a

Materials and methods: A total of 60 specimens were obtained from the posterior arches of 30 precontoured trademark TP Orthodontics (La Porte, Indiana) wires and were divided into three groups of 20


Reduction in the Modulus of Elasticity in Orthodontic Wires
The modulus of elasticity of stainless steel orthodontic wires was found to be 20% below the normally assumed range of 19.3 to 20.0 X 104 MPa (28.0 to 29.0 × 106 psi). Use of the latter value can
