Comparative Analysis of Sliding Resistance of Different Lingual Systems
Objective: To analyse and compare the frictional properties of 4 lingual systems combined with two types of stainless steel archwire (0.016x0.022, 0.018x0.025) and a 0.018x0.025 TMA archwire by simulating different misalignment situations in vitro.Material and Methods: Five randomly chosen brackets from little boys pants each system (e-Brace, Harmo
