The horizontal fixation pins are used to anchor the surgical template during the initial phase of the surgical procedure. These pins are placed in a pre-drilled hole in the cortical bone and guided by a fixation guide sleeve in the surgical template. The vertical fixation pins are used to ensure the additional stabilization of the surgical template after the implant placement phase. The vertical fixation pins are color-coded in accordance with the color of the prosthetic platform. Yellow for the QN prosthetic platform, blue for the QR prosthetic platform.
