Head technology The smaller the head the better the access to and view of the treatment site. The purchaser should consider not only the diameter and the height of the head but also the working height (head + bur). The smallest dental turbine units have a working height of about 17 mm (with a bur length of 16 mm). The heads of these miniature turbines have a diameter of less than 9 mm and a height of approx. 10 mm. Despite their very small size, they still offer high power. The products had to be designed with special applications in mind to allow such small head dimensions. This means that microturbines can be used for minimally invasive applications and for patients with a small mouth opening (children and older patients). Some manufacturers have even integrated two impellers into the turbine to meet these requirements. The turbine rotor tends to suck air from its immediate vicinity when slowing down. Consequently, there is a danger of sucking contaminated air into the interior of the turbine. Modern turbines now have what is referred to as a hygienic head. This innovative system prevents external air from being sucked into bypass channels. Speed range The idle speed (approx. 400,000 min-1) of turbines is an indicator of their cutting performance. The advantage of electric motors is that the speed and torque can be very easily controlled. The speed of brushless electric motors can be controlled within a range of approx. 100 to 40,000 min-1. These motors offer a stable torque throughout their entire speed range. More and more dentists are using electric motors. When service life, hygiene, wear and sterilizability are considered, brushless electric motors are to be preferred to motors with brushes. Check here more “china dental equipment”.
