LUBRICANT FOR ROTARY INSTRUMENTS PROCLINIC 500ML - REF:849

The way in which lubrication is carried out, and the quality of the lubricant used, largely determines the service life of rotary instruments.

The faster a rotary instrument spins, the more important it is that lubrication is carried out correctly.

Lubrication is therefore essential for all rotary instruments, and particularly for turbines and red-ring contra-angles.

The turbine is driven by a jet of air pushing on blades attached to a rotor. The rotor is held in place by ball bearings. The rotor can spin at +/- 300,000 revolutions per minute (5,000 revolutions in a single second… !!!!). If, inside the ball bearing, the balls are not coated in a film of grease — reducing friction and therefore the heat generated by friction — you will very quickly destroy the ball/ball cage assembly. The bearing will develop play, will become noisy, and the bur will no longer be held in its axis. This can even end in the bearing exploding with a dispersal of micro balls, possibly even in the patient's mouth!!!

For the red-ring contra-angle, it is even worse, because even though it rotates more slowly, the entire kinematic chain is made up of gears — from the entry of the contra-angle to its output (the bur). The red-ring contra-angle increases the speed imparted by the micromotor, generally by a factor of 5. (One revolution at the input, five at the output), which means that with a micromotor running at 40,000 rpm, the bur of a red-ring contra-angle rotates at 200,000 rpm, or 3,300 revolutions per second…. That is absolutely colossal. Here too, if a film of grease does not coat the gears/balls of the bearings, the materials will heat up, then metal will be torn away… It is the beginning of the end.

We use this lubricant in our workshop because it is of excellent quality.

We believe that from a lubrication standpoint, and especially for fast-rotating instruments, spray lubrication is preferable to automated machine lubrication. Or, at the very least, before autoclave sterilisation, supplement the automated lubrication with a spray lubricant injection.

The problem with automated lubricators is that in principle they are perfect, but in practice, if for one reason or another the lubricant is not distributed properly throughout the entire kinematic chain, you will have a lubrication defect leading to rapid deterioration of the instrument.

Lubricate through the base of the instrument until the lubricant comes out through the head. (Hold the instrument with the base facing up and the head facing down). If, when the product is ejected through the head, the lubricant comes out black or dark in colour, continue injecting until the product comes out pure/clear — this way you will have cleaned out the surplus lubricant that was heated during use. This ensures at minimum that the instrument is lubricated and thoroughly cleaned. (With automated lubrication, for example, it is not possible to ensure that the instrument is "clean")

Once this is done, add a little lubricant into the head through the bur insertion hole. This will ensure perfect lubrication.
