2009/2/17
Using specular reflectance, the surface roughness of six representative orthodontic archwire products was determined. Among the four alloy groups which are commonly used in orthodontics, stainless...
Comparisons of the thermodynamic properties of three nickel-titanium orthodontic archwires
Thermodynamic archwires Nitinol Recovery TTR

2009/1/4
Twenty-six archwires and 24 brackets were selected from among the hundreds of products available that nominally have from 18 to 22 mil bracket slots and 14, 16, 17, 18, 19, and/or 21 mil archwire size...
Thermal Analysis of As-received and Clinically Retrieved Copper-nickel-titanium Orthodontic Archwires
Thermal analysis DSC Copper-nickel-titanium Archwires
