The main difference is their file type. ProTaper Gold is a rotary file system based on a multiple file sequence and WaveOne Gold is a reciprocate file system based on a single file sequence.
The ProTaper Gold technology includes a series of “Shaping” and “Finishing” files that create the predictable ProTaper shapes. ProTaper Gold rotary files create the same smoothly tapered shapes as ProTaper Universal1 while delivering significant new advantages:
ProTaper Gold has a shorter handle length than previous ProTaper files, namely 11 mm.
