**1. Introduction**

Over the past years, virtually planned surgery has been increasingly utilised in maxillofa‐ cial reconstructive surgery. The concept of computer-aided surgery uses surgical simula‐ tion and three-dimensional (3-D) computer-aided designed/computer-aided manufactured (CAD/CAM) tools such as cutting guides and jigs rather than relying exclusively on intraoperative manual approximation for facial reconstruction [1].

The advantage of virtually planned surgery over conventional surgery has indisputably less deviation between reconstructed and natural bony landmarks [2]. Nevertheless, the amount of time saved by using the CAD/CAM approach is subject to controversy. On the one hand, microsurgical craniofacial reconstruction using computer-assisted techniques, such as for fibula-flap harvesting, has yielded significantly shorter ischemia times even with a larger number of osteotomies compared with conventional techniques [3]. On the other hand, the time savings should be considered in light of the additional time needed to complete the preoperative virtual modeling session, which can take up to an hour. So if saving time were a means of recouping the added cost of the CAD/CAM technique, the overall operative time should not be different from that of the conventional technique [4]. However, no differences between the techniques exist with respect to perioperative and long-term outcomes, length of hospital stay, recipient-site infection, partial and total flap loss, or rate of soft-tissue and bony-tissue revisions [3].

We report herein our experiences using CAD/CAM techniques in five separate cases and discuss them on the basis of recent criteria for the usage of CAD/CAM techniques given in the literature.
