The mechanical behavior of as received and retrieved nickel titanium orthodontic archwires
Progress in Orthodontics - Tập 20 - Trang 1-8 - 2019
Luca Lombardo, Giorgia Toni, Valentina Mazzanti, Francesco Mollica, Giorgio Alfredo Spedicato, Giuseppe Siciliani
The aim of this study is to investigate and compare the characteristics of as received and retrieved NiTi archwires at a constant temperature by plotting their load/deflection graphs and quantifying three parameters describing the discharge plateau phase. Two hundred four NiTi archwires, traditional and heat-activated, of various cross sections, were obtained from 5 different manufacturers. Specim...... hiện toàn bộ

Comparison of survival time between two types of orthodontic fixed retainer: a prospective randomized clinical trial
Progress in Orthodontics - Tập 14 - Trang 1-6 - 2013
Parisa Salehi, Hooman Zarif Najafi, Seyyed Mehdi Roeinpeikar
The aim of this prospective clinical study was to compare the mean durability and the failure rates of two types of orthodontic retainers. Orthodontic patients (142) aged between 14 and 28 years were recruited in this study. The polyethylene woven ribbon (Ribbond, Seattle, WA, USA) retainer was compared with a 0.0175-in flexible spiral wire (Respond, Ormco, Glendora, CA, USA) retainer. When treatm...... hiện toàn bộ
Long-term antimicrobial assessment of orthodontic brackets coated with nitrogen-doped titanium dioxide against Streptococcus mutans
Progress in Orthodontics - Tập 19 - Trang 1-6 - 2018
Parisa Salehi, Neda Babanouri, Mehdi Roein-Peikar, Fatemeh Zare
The antimicrobial properties of orthodontic wire and brackets with nitrogen-doped titanium dioxide (N-doped TiO2) coating have been studied in the past. However, the evaluation period had been short and limited to 30 days. The aim of the present study was to extend the evaluation period (up to 90 days) of assessing the long-term antimicrobial effects of stainless steel orthodontic brackets coated ...... hiện toàn bộ
Effect of pH on in vitro biocompatibility of orthodontic miniscrew implants
Progress in Orthodontics - Tập 14 - Trang 1-7 - 2013
Angela Galeotti, Roberto Uomo, Gianrico Spagnuolo, Sergio Paduano, Roberta Cimino, Rosa Valletta, Vincenzo D’Antò
Although the clinical use of miniscrews has been investigated on a large scale, little is known about their biocompatibility. Since low pH can affect corrosion resistance, the aim of this study was to evaluate the cytotoxic effect of orthodontic miniscrews in different pH conditions. Four orthodontic miniscrews of stainless steel and grade IV and grade V titanium were immersed in a pH 7 and pH 4 s...... hiện toàn bộ
Three-dimensional evaluation of root dimensions and alveolar ridge width of maxillary lateral incisors in patients with unilateral agenesis

Invisalign technique in the treatment of adults with pre-restorative concerns
Progress in Orthodontics - Tập 14 - Trang 1-9 - 2013
Gianluca Mampieri, Aldo Giancotti
The Invisalign method is gaining an increasing interest as an alternative treatment option in adult patient in multidisciplinary complex cases to simplify the treatment plan. The aim of this work is to show the importance of planning a multidisciplinary approach to respond at the esthetic requests of adult patients and to treat complex cases with high predictability.
Comparison between rapid and mixed maxillary expansion through an assessment of dento-skeletal effects on posteroanterior cephalometry
Progress in Orthodontics - Tập 15 Số 1 - 2014
Letizia Perillo, Alfredo De Rosa, Francesco Iaselli, Fabrizia d’Apuzzo, Vincenzo Grassia, Salvatore Cappabianca
Abstract Background The aim of this study is to compare the dento-skeletal effects of rapid maxillary expansion (RME) and mixed maxillary expansion (MME), assessed on posteroanterior (PA) cephalograms. Methods... hiện toàn bộ
Torque efficiency of square and rectangular archwires into 0.018 and 0.022 in. conventional brackets
Progress in Orthodontics - Tập 17 - Trang 1-6 - 2016
Spyridon N. Papageorgiou, Iosif Sifakakis, Ioannis Doulis, Theodore Eliades, Christoph Bourauel
The aim of this study was to compare the torque efficacy of square and rectangular wires in 0.018- and 0.022-in. conventionally ligated brackets. Brackets of the same prescription were evaluated in both slot dimensions. Identical acrylic resin models of the maxilla were bonded with the brackets and mounted on the Orthodontic Measurement and Simulation System. Ten 0.018 × 0.018 in., 0.018 × 0.022 i...... hiện toàn bộ
