Aim. To compare and evaluate the static frictional resistance offered by the four different types of ligation methods in both dry and wet conditions and at different durations when immersed in artificial saliva. Material and Methods. Alastik Easy to Tie modules, Super Slick Mini Stix elastomeric modules, Power "O" modules, and 0.009(″) Stainless Steel ligatures were used to compare the static friction using maxillary canine and premolar Preadjusted Edgewise brackets with 0.022(″) × 0.028(″) slot and 0.019(″) × 0.025(″) stainless steel wires. Results. The mean frictional resistance for Alastik modules was the lowest and that of Stainless Steel ligatures was found to be highest among the four groups compared and the difference among the four groups was statistically significant (P < 0.005). The mean static frictional resistance in all groups under dry conditions was lower than that under wet conditions. No statistical significant differences were found when the groups were compared at different time periods of immersion in artificial saliva. Conclusion. This study concludes that the Alastik modules showed the lowest mean static frictional forces compared to any other ligation method, though no significant difference was found for different time periods of immersion in the artificial saliva.
目的。比较和评估四种不同类型的结扎方法在干燥和潮湿条件下以及浸入人工唾液不同时长时所提供的静摩擦阻力。材料与方法。使用Alastik易结扎模块、超级顺滑迷你结扎圈弹性模块、动力“O”型模块以及0.009（英寸）不锈钢结扎丝，结合上颌尖牙和前磨牙预成方丝弓托槽（槽沟尺寸为0.022（英寸）×0.028（英寸））和0.019（英寸）×0.025（英寸）不锈钢丝来比较静摩擦力。结果。在比较的四组中，Alastik模块的平均摩擦阻力最低，不锈钢结扎丝的平均摩擦阻力最高，四组之间的差异具有统计学意义（P < 0.005）。所有组在干燥条件下的平均静摩擦阻力低于潮湿条件下的。在人工唾液中浸泡不同时间段后比较各组时，未发现统计学上的显著差异。结论。本研究得出结论，与任何其他结扎方法相比，Alastik模块显示出最低的平均静摩擦力，尽管在人工唾液中浸泡不同时间段未发现显著差异。
