The aim of this study is to the effect aging in different media (deionized water and artificial saliva) on force/torque generation by thermoplastic orthodontic aligners. Ten thermoformed aligners, made Essix ACE® sheets, were aged deionized saliva over two weeks at 37 °C, five each medium. generated upper second premolar (Tooth 25) a resin model was measured day 0 (before aging), 2, 4, 6, 10, 1...

Nickel-titanium archwires in orthodontic wires have nickel ion releases. The use toothpaste and saliva immersion time may cause its This study aims to prove the difference interaction between variations towards amount of releases at nickel-titanium archwires. was an experimental research with a post-test only control group design. Twenty seven were divided into three groups, i.e., K group, whic...

Introduction: The aim of this study was to assess the galvanic behavior of different bracket and archwire combinations that are commonly used in orthodontic treatments. Methods: Three types of orthodontic archwires with a diameter of 0.016×0.022 inch and 80 standard edgewise maxillary central incisor brackets were selected. Three groups consisted of different wire-bracket couples and one group ...

This study aimed to compare the color stability and surface roughness of three-dimensional (3D) printing resin according polishing methods. 3D-printed specimens were fabricated at TC-80DP (Graphy, Seoul, Korea) with a stereolithography 3D printer, divided into three groups, each which was not polished, polished using Enhance®, Sof-Lex<sup>TM</sup> disc. The CIE L*a*b* value group me...
