Prosthetic rehabilitation with implant-supported prostheses is considered to be a routine procedure with high success rates. The assumed benefit of the computer-assisted implant planning and subsequent template guided implant placement is a thorough preoperative diagnostic and a more predictable implantation procedure with respect to anatomical structures and prosthetic aspects. Hence, adequate precision of implant placement provided, prefabrication of prosthetic reconstructions specially for immediate loading situations may be possible.
But how high is the level of accuracy of such procedures? Although computer-guided implant dentistry is a widespread technology with the potential for more predictive and less invasive implant placement, its performance has to be critically evaluated.
