Evaluation of Mechanical Properties and Comparison with Titanium Alloy Alternatives
ELASTICITY MULTISTRANDED WIRE STAINLESS STEEL TITANIUM WIRE
2009/2/26
Force storage and delivery properties of typical triple-stranded stainless steel wires are determined and compared with reported values for titanium alloy archwires. Results indicate that triple-s...
Endosseous implants in dogs are used successfully to apply orthodontic and orthopedic forces. Not all experimental implants remained firm enough through the initial healing period to be used for a...
The effect of long-term deflection on permanent deformation of Nickel-Titanium archwires
Orthodontic wires Nitinol Spring back Permanent deformation Stress-relaxation
2009/1/23
The clinician must now consider the alloy along with cross-sectional shape and size when selecting archwires. The purpose of this study is to quantify permanent deformation after long-term deflect...
Nickel-titanium spring properties in a simulated oral environment
Nickel-Titanium Spring Mechanics
2009/1/12
A study of nickel-titanium springs was undertaken to determine whether their mechanical properties are affected by prolonged exposure to a static, simulated oral environment. Stainless steel springs...
Repelling magnets versus superelastic nickel-titanium coils in simultaneous distal movement of maxillary first and second molars
Dental alloys Magnetics Supercoils Force Orthodontic appliance Molar Tooth movement
2009/1/12
Eighteen subjects, aged 12.5 to 18.3 years, with Class II malocclusion, deep overbite and moderate space deficiency in the maxilla were treated orthodontically using repelling rare earth magnets on on...
Comparisons of the thermodynamic properties of three nickel-titanium orthodontic archwires
Thermodynamic archwires Nitinol Recovery TTR
2009/1/12
The unique memory property of thermodynamic wire is only partially understood. It is believed to result from the wire's inherent capability to markedly alter its atomic bonding forces as a function of...
