  • Dental Drill - an overview | ScienceDirect Topics

    Dental burs have revolutionized the dentistry field and are used for cutting hard tissues such as bone or tooth [1,4,6–9]. They are normally made of stainless steel, diamond grit or particles, and tungsten carbide and fitted to a dental drill incorporating an air turbine. The dental bur was developed <300 years ago [8] and still widely used.

  • Mammalian dental function and wear: A review -

    2015-3-1 · Enamel is the first line of defense and the tissue most commonly considered in studies of dental fracture properties. Mammalian enamel strength comes from both its chemistry and its structural properties. It is on average about 97% mineral, almost entirely hydroxyapatite, Ca 10 (PO 4) 6 (OH) 2. The rest is water and trace amounts of organic compounds.

  • Dental Air Compressor Guide - Eclipse Dental

    An air turbine handpiece is a dental abrasive device that rotates at high speed and uses compressed air as the driving force. It is characterized by its small size, light weight, and painless abrading due to its high-speed rotation, but its torque is small and noise level is high. Thus, to improve the performance of the air turbine handpiece, we conducted a performance test of an actual ...

    2008-3-17 · A Plexiglas™ jig was designed with a three-axis translation stage (± 0.1 mm accuracy), a goniometer (± 0.1 ° accuracy), and a two-axis tilt stage to allow the transducer to be precisely maneuvered relative to the dental hard tissue and phantom specimens. The specimens were mounted with wax on a stainless steel ring to provide an air backing, thereby maximizing reflected echo strength.
