ABSTRACT:
About 1/2 cc of a sterile composition (5) dropped into the rotor drive air feed line (11) of a dental handpiece (10) while holding the handpiece upside down protects and lubricates the handpiece bearings and turbine during the subsequent auto-clave sterilization process. An additional dosage inserted into the bur hole after the auto-clave process further lubricates the handpiece and inhibits rust from forming on the handpiece bearings and turbine during use. The pre-sterilization dosage and post-sterilization dosage of measured amounts may be separately packaged in disposable capsules (20, 30). The composition (5) is made by heat mixing until sterile about 10% by volume of a sterile solution of Power-Up.TM. NNL-690, which is a liquid hydrocarbon boundary lubricant; and corrosion inhibitor, with 90% by volume of pharmaceutical grade mineral oil.
