(a) Force in x-axis direction Fx and (b) force in y-axis direction Fy. The x-axes in the graphs depict time (s) and y-axes is force in Newtons. It can be assumed if the rest of the percentages are clear if it is a resin (i.e. 10% castable and 90% clear) and 100% clear if it is a powder (gypsum, Kevlar). The spectra are not completely overlapped due to minuscule varying placements of the specimens during testing in the sagittal and coronal planes. A few millimeters difference in position can lead to a difference in when the bur hits the sample
