The peak von Mises stress on mini-screw-implanted bone with a load of 2.0 Newtons (2D view from above). (a,c) Removal group. (b,d) Penetration group. (a,b) Cortical bone thickness of 1.0 mm. (c,d) Cortical bone thickness of 2.0 mm. The peak von Mises stress on the surrounding bone with 1.0 mm of the cortical bone was 3.3 megapascals (MPa) in the removal group and 11.3 MPa in the penetration group. With 2.0 mm of the cortical bone, it was 3.2 MPa in the removal group and 11.1 MPa in the penetration group.
