Abstract:
The bracket-archwire interface friction is one of the factors that influence the efficiency of orthodontic tooth movement and the total time of treatment. Therefore, it is of interest to compare ceramic, passive self-ligating and conventional metal bracketries in relation to their frictional characteristics for determing the types of archwires and their sizes with the bracketries. Frictional forces Frictional forces were measured under standardized conditions using 240 combinations of bracket-archwire through a universal testing machine. Brackets with the least friction were the self-ligating ones and the brackets with the highest friction were the ceramic ones, particularly with rectangular NiTi and beta-titanium wires. The self-ligating systems come with the benefit of high low-friction performance that improves treatment performance on the traditional and ceramic brackets.
