In the first part of this series, published last week (OGJ, Feb. 4, 2008, p. 46), we began to show how roller cone bit design analysis can predict cone behavior, with heel teeth having equal pitch.

The calculation method proposed in this series, using actual gear ratio for the cones, allows the designer to determine and optimize kinematic parameters of drill bits. The analysis is applicable to ...

A majority of dental schools in the U.S. own cone-beam CT (CBCT) systems and have incorporated training in 3D image interpretation into their curriculums, according to research presented at the recent ...

August 9, 2012 — New guidelines on cone beam computed tomography (CT) scanning by the Scientific Affairs Council of the American Dental Association (ADA) imply that dentists could be responsible for ...
