Abstract

Tip control in lingual orthodontics may be challenging because of the presence of a vertical slot and the particular configuration of the customized appliances. The aim of this in vitro experimental study was to investigate the role of the ligature–wire–slot system in achieving better tip control. A set of customized lingual brackets was obtained for a dedicated typodont made of extracted human teeth. A compression/traction machine tested two types of ligatures in combination with seven different wires, and the tipping angle of each configuration was derived. A statistically significant difference was found between ligatures when the complete set of data was tested. In addition, differences between ligatures were found when testing each wire separately. A statistically significant difference was found among all wires. Full-size wires showed the smallest angles, which correspond to the greatest efficiency of the slot–archwire–ligation system in terms of tip control, and this efficiency appeared to be ligature-related. The role played by the type of ligature was more relevant for undersized wires.

定制语言器具的尖端效率：两种不同结扎线的性能。

由于存在垂直槽和定制器具的特殊配置，舌正畸的尖端控制可能具有挑战性。本体外实验研究的目的是探讨结扎-线槽系统在实现更好的尖端控制中的作用。一套定制的舌托是为一个专用的排版，由拔出的人的牙齿。用压缩/牵引机测试了两种类型的结扎线与7种不同的钢丝的组合，并推导了每种配置的倾斜角。当完整的数据集被测试时，结扎之间发现了统计学上显著的差异。此外，在分别测试每根电线时，发现了结扎之间的差异。在所有电线之间发现了统计学上显著的差异。全尺寸钢丝的角度最小，这与槽弓钢丝结扎系统在尖端控制方面的最高效率相对应，这种效率似乎与结扎有关。结扎类型所起的作用与尺寸较小的电线更相关。

期刊介绍： The European Journal of Oral Sciences is an international journal which publishes original research papers within clinical dentistry, on all basic science aspects of structure, chemistry, developmental biology, physiology and pathology of relevant tissues, as well as on microbiology, biomaterials and the behavioural sciences as they relate to dentistry. In general, analytical studies are preferred to descriptive ones. Reviews, Short Communications and Letters to the Editor will also be considered for publication. The journal is published bimonthly.
