“V” Spring for Reactivation of NiTi Open Coil Spring

Abstract

The NiTi open coil spring is commonly accustomed to creating spaces for crowded teeth. It is difficult to anticipate the length of the open coil spring desired to open up the exact quantity of space; sometimes, the length of the open spring falls short of opening up the space required. In such a case, the base arch wire must be taken out and replaced with an expanded open coil spring, which is both difficult and time-consuming. There are various reactivation methods available, such as split tubings, cutting a C-shaped tube to the desired length, adding extra length to the spring, creating C-rings, and using composite beads. Hence, we have designed a very simple yet effective chairside method to reactivate NiTi open coil spring with the removal of base arch wire.
