Most lubricants on the market are mineral based, cheaper to produce, and far inferior to synthetic lubricants. Mineral based oils are naturally occurring and have impurities such as sulfur, tars, varnishes, metals, and phosphorus. These impurities are all various shapes and sizes. The inconsistent nature of these molecules does not allow for optimum smoothness of the lubricated surfaces. In addition, once autoclaved, these minerals thicken and become baked onto the internal surfaces of the handpiece. This added friction slows down the turbine and decreases torque.
Synthetic lubricants are lab created to be exactly how they are needed. This allows for maximum purity and consistency for the best lubrication and protection. The consistent nature of lab created synthetic oils is much stronger and able to
withstand the autoclaves high temperatures. No impurities means a more slippery surface to protect bearings and all
moving parts.
