The Turbine Assembly of High-Speed Dental Handpieces – Part Two

turbineExtending the Life of the Turbine Assembly Starts with Improvements in the Cage

There are other small components included in the turbine assembly. These include the chuck and the end-caps. These parts are in addition to the parts that have been previously mentioned in this guide. If you want to extend the life of the dental handpieces in your practice, you must start by extending the life of the turbine assembly. This is done by improving the cage or the retainer piece. Based on studies, manufacturers have immensely improved the materials that are used to create the cage. Additionally, regular and/or routine sterilization also assists in extending the life of the cage. The following outlines additional measures to extending the life of the turbine assembly:

  • If you would like to extend the life of the dental handpieces within your practice and reduce the amount of handpiece repair that is necessary over time, you may opt for dental handpieces that are advertised as being “lube-free” and/or “maintenance-free”.
  • Today, there is a highly-innovative application available for bearings that is composed of silver that contains a very high level of purity. Not only does this coating lubricate the parts but it enhances the strength of the bearings. This will assist in ensuring that the dental handpieces in your practice have the unique ability to withstand the repetition of the autoclave cycle of the device.
  • In order to extend the life of your instruments, you should ensure that the air pressure that enters into the handpiece is not considered to be “excessive”. You may use an in-line gauge to measure the overall air pressure of the dental handpiece at the connection point of the instrument.
  • In order to protect the turbine assembly, you should ensure that the quality of the drive air is high. Over time, the oil and moisture may start to build up in the compressor tank. When this happens, the substances may easily move through the lines that move the air through the instruments. This could affect the functionality and the reliability of your instruments. Simply ensure that you engage in drying and/or filtrating your dental handpieces on a regular basis.
  • The next method to extending the overall life of the dental handpieces and turbine assemblies in your practice is to hire a dental handpiece repair specialist several times each year to inspect the dryers of the device, examine the filters, test all of the connections, and to completely drain the compression tank.


The turbine assembly makes the dental handpiece; however, it also has the unique capability of breaking the dental handpiece. It is imperative that you learn all that you are able to about this assembly and all of the components involved. By performing regular maintenance and following the advice contained in this guide, you are sure to find that your dental handpieces function optimally at all times.
