Influence of long-term in vivo exposure, debris accumulation and archwire material on friction force among different types of brackets and archwires couples

ConclusionA significant correlation was seen between friction force and bracket type, while treatment duration, amount of debris accumulation, archwire material or their manufacturer was not significantly correlated to it. Nevertheless, higher friction forces were measured amongin vivo aged SL brackets in comparison with as-received ones.
