Featured article: A finite element analysis of the effects of archwire size on orthodontic tooth movement in extraction space closure with miniscrew sliding mechanics

© Kawamura & Tamaya, 2019Sliding mechanics is a standard method used for extraction space closure. Although the retraction force decays by friction between the archwire and the bracket slot, the bracket slids along the archwire so that bodily tooth movement can be easily achieved.

In this study, Kawamura and Tamaya investigate the affects of archwire size on long-term tooth movement in miniscrew sliding mechanisms. Findings reveal that with a decreasing archwire size, a play of the archwire-bracket slot along with the elastic deformation of the archwire resulted in lingual tipping of the incisors.

Aims and scope

Progress in Orthodontics is a fully open access, international journal owned by the Italian Society of Orthodontics and published under the brand SpringerOpen. The Society is currently covering all publication costs so there are no article processing charges for authors.

It is a premier journal of international scope that fosters orthodontic research, including both basic research and development of innovative clinical techniques, with an emphasis on the following areas:
• Mechanisms to improve orthodontics
• Clinical studies and control animal studies
• Orthodontics and genetics, genomics
• Temporomandibular joint (TMJ) control clinical trials
• Efficacy of orthodontic appliances and animal models
• Systematic reviews and meta analyses
• Mechanisms to speed orthodontic treatment

Progress in Orthodontics will consider for publication only meritorious and original contributions. These may be:
• Original articles reporting the findings of clinical trials, clinically relevant basic scientific investigations, or novel therapeutic or diagnostic systems
• Review articles on current topics
• Articles on novel techniques and clinical tools
• Articles of contemporary interest

Submitted manuscripts will be reviewed by at least two referees.
