PROSTHETIC GUIDED DISTRACTION VECTOR - Well positioned implants, due to correct inclination of the distraction vector (lower right) - An incorrect distraction vector (lower left) could have resulted in an suboptimal position of the distracted bone and could have compromised the positioning of the implants and the prosthetic result
