Figure 4

Implant insertion with hand ratchet. The ratchet connector has six green vertical landmarks (corresponding to implant hex) and a horizontal reference line. In order to reproduce the planned implant position, the horizontal reference line should match with the upper border and the green vertical landmark with the window of the surgical template.
