Please stay in close touch with us and be assured that all of our physicians want their patients to come to them, as needed, with questions and concerns. HOW TO CHECK THE ROOT RADIUS The thread's helix spiral pattern acts like an inclined plane that translates rotational movement to axial movement while gaining some mechanical advantage. That is because the plating itself is parallel to the thread flanks, and the PD is measured perpendicular to the thread axis. MIN= minimum
