Mechanical and Histological Effects of Resorbable Blasting Media Surface Treatment on the Initial Stability of Orthodontic Mini-Implants

Figure 3

Schematic graph to explain the mechanical characteristics of mini-implants. (A) Maximum insertion torque (MIT). (B) Time of MIT. (C) Maximum removal torque (MRT). (D) Time of MRT. (E) 1.5 seconds after MRT, which is the time needed for a half turn. (F) Removal angular momentum (RAM), which is the torque integrated from the time of MRT to 1.5 seconds under 20 rpm after MRT.
