If the friction resistance is high, slow progress and unnecessary elongation of the treatment time might result. Consequently, a practitioner must apply greater mechanical forces to overcome the frictional force progressively throughout the treatment. Friction is affected by physical and biological factors. The physical factors have been thoroughly studied in the literature. These physical factors are related to the bracket and arch wire properties and the ligation methods. The current knowledge on the subject is based on in vitro studies that, in most instances, produced conflicting results. This could be due to the inherent limitations of these studies as standardization of methods, or difficulty in simulating the oral environment and its effect on the surface characteristics of the materials used.
