<h1>What affect Dental Handpiece Torque?</h1><strong> Author: <a href='http://www.articleseen.com/profile_William Bruse.aspx'>William Bruse</a></strong><br /><p>Dental handpiece head sizes always include large, standard, and mini.. Many manufacturers feel the most limiting measurement is front to rear, which is tip of the chuck to very back of handpiece head. This measurement will typically be around 12 mm, or so, and helps determine the height of handpiece with selected bur installed. What affect Dental Handpiece Torque? 1. Bearings. Bearings can also be a limiting factor in dental handpiece torque. Bearings are very specialized and must be chosen with a high degree of accuracy for each application. Some designs are capable of producing very good torque at slower speeds, but will quickly lose effectiveness at higher speeds, as heat and other factors must be taken into consideration. The expansion and contraction resulting from the rigors of the dental environment will quickly affect bearings not designed for such. Myonic.. 2. Impellers. Impellers are made from composite materials which tend to handle the harsh environment of the autoclave without excessive expansion or tendency to become brittle. Impellers which are not properly balanced can greatly affect dental handpiece torque, especially when varying handpiece speeds are required to complete a preparation. All dental turbines have critical speeds (speeds at which turbine operates at a higher vibration level). Well balanced impellers help to reduce this range to a minimum, resulting in more constant dental handpiece torque throughout. Some impellers are not balanced at all. This combined with less expensive (and effective) bearings is why you may find a wide range of turbine dental equipment prices on the internet. In many cases these turbines will provide very good service. I guess buyer beware is in order here. If you replace turbines yourself, take a close look at the impeller. Balanced impellers will typically have small indentations on one or more of the impeller blades, often in a different color. Of course, turbines with less expensive bearings and unbalanced impellers are good choices for some, when absolute maximum dental handpiece torque is not required. However, if you are the type to drive a Mercedes, you may expect it to run like one. Since you know the reasons affect Dental Handpiece Torque, you can choose them more easily. </p><strong>About the Author:</strong><br /><a rel="nofollow" href=" http://www.izidental.com/dental-handpiece.html"> dental handpiece</a> <a rel="nofollow" href=" http://www.izidental.com"> dental equipment</a> <a rel="nofollow" href=" http://www.izidental.com"> dental supply</a><p> Article Source: <a href='http://www.articleseen.com/Article_What-affect-Dental-Handpiece-Torque_120334.aspx'> http://www.articleseen.com/Article_What affect Dental Handpiece Torque?_120334.aspx</a></p>
