Answer
Using improper tools like screwdrivers or standard pliers to install spiral rings is a major cause of failure. These tools apply 'point loads' rather than uniform radial pressure, which can cause 'local yielding' or 'kinking' of the ring. A kinked ring will not sit flat in the groove, leading to 'point loading' on the groove wall and premature failure. Furthermore, screwdrivers often scratch the material, creating 'stress risers' that initiate fatigue cracks. For manual installation, a 'Dental Pick' or a specialized 'Spiral Ring Tool' should be used to gradually wind the ring into the groove, starting from one end and moving around the circumference.
