Fundamentals of repair of dental hand pieces

Today we are going to talk about the repair of dental tips. The repair of a high speed drill includes the replacement of the bearings and the sealing rings in the turbine. Thorough cleaning is also necessary to eliminate corrosion caused by the autoclave.

After removing the back cover and removing the turbine from the head, the sealing rings are removed and the back cover and cover are completely clean. If washers are used in the design of the tip, they are also removed and cleaned.

The turbine is built with a cartridge that you put in your burrs.

The cartridge can be a push or friction lever. The cartridge also acts as an axis to install the impeller and bearings. The O-rings are located on the head and on the back of the tip.

The impeller is mounted in the center of the cartridge. The location of the impeller is very important and requires precise measurements to determine the correct location. The bearings are located on each end of the impeller in the mandrel. All these pieces are pressed for gazebos.

After assembly, the bearings should be lubricated with oil designed specifically for high speed bearings. It is important to keep in mind that some bearings do not require lubrication. The ceramic bearings are an example. Talk to your service provider to discuss the best bearings for the dental handpiece repair.

After completing this procedure, the restored turbine is ready to be reinstalled in the head of the tip, which we just cleaned. Simply insert the turbine in its place and screw the back cover on the head. If the repair of the dental handpiece is done correctly, the handpiece will work like new.

As for maintenance, two or three drops of oil should be placed in the air hole in the bottom of the tip. Perform this task in accordance with the manufacturer’s instructions. However, in most cases, the lubricant must be after the autoclave. When lubricating your handpiece, make sure it runs for thirty or forty seconds to make sure that the bearings are fully lubricated and that excess oil is expelled from the handpiece.

Finally

You can remember that before autoclaving, you should clean the tip to eliminate any organic matter that can corrode the tip. Also, do not forget the fiber optic, since organic and other materials can adhere to the lens during the autoclave and reduce function. A soft bristle brush and warm water are all you need. Do not use detergents or soap, as they can damage the optics. The soap can also penetrate the bearings and reduce lubrication, which reduces the life of your dental handpiece.
