Easy open and close
The slot of PROTECT IV self-ligating brackets are opened by twisting the sliding lid to gingival direction. This special design makes the brackets aggregate towards the gingival side. Therefore, the height of occlusal tie-wings is lower, which avoids occlusal interference between the brackets and corresponding teeth in the opposite arch, and reduces the expulsion rate of brackets and further improves the comfort of patients.
