Torque capacity of metal and polycarbonate brackets with and without a metal slot [PDF]
The European Journal of Orthodontics, 2004 The aim of the present study was to investigate slot deformation and the equivalent torque capacity of polycarbonate brackets with and without a metal slot in comparison with those of a metal bracket. For this purpose, the expansion characteristics and, in a further investigation, the labial crown torque of an upper central incisor, were measured in a ...
