For many dental treatments, a turbine is an essential tool. Considering the wide choice of models featuring similar performance, let's try to clarify the most important features when choosing a device.
A turbine is a rotating instrument that works thanks to compressed air and can rotate at very high speeds of around 400,000 rpm. These features make the turbine an ideal tool for abrading or cutting tooth enamel and materials used in fixed prostheses.
High speed produces a considerable amount of heat and therefore requires some form of cooling of the treatment area. Irrigation with air and water is essential to avoid damaging the tooth pulp, keeping the heat generated by friction as low as possible.
It is generally best to have three or four irrigation points. These allow to obtain:
Moreover, the spray action efficiently keeps the operating field clear of residues produced by the use of the turbine.
Inside the turbine there is a rotor with blades which, hit by the compressed air, will rotate.
While using the turbine, the dentist acts on the foot control to adjust the operating pressure gradually and progressively. These adjustments drive the unit's speed up to the maximum achievable value.
In addition to the rotor, other important components of the dental turbine are the bearings - which must withstand friction throughout the life of the instrument. Together with proper handpiece lubrication, bearing quality contributes to a longer lifespan and ensures optimum performance.
Regular lubrication and regular maintenance ensure longer life and consistent performance. We suggest following the manufacturer's instructions for any dynamic tool.
Today, there are devices on the market that carry out automatic lubrication and purging of the turbine and other rotating instruments. Devices like Thalya can handle the procedure easily. Cleaning, disinfection and drying phases are also possible with Thalya Plus Plus. By following the manufacturer's recommendations, the turbine is sterilized in an autoclave to complete the instrument reconditioning.
There are many aspects behind the choice of a turbine. Cost should be a consideration, while at the same time setting a quality threshold below which not to go.
What are the key features that should matter to us? Anything that relates to the effectiveness and durability of the handpiece.
