Future Technology and Evolving Techniques

The use of axial imaging, particularly CT, has greatly enhanced understanding of discontinuity, bone loss and remaining bone quantity and quality, and the importance of implant location. In addition, recently available 3D reconstructions and 3D printed models can assist surgeons in preoperative planning and intraoperative execution (Figure 12). Although custom triflange implants currently are generated based on a CT scan and 3D modeling, in the future, such custom constructs may be generated via 3D printing, which would allow modification of metal composition as well as more expeditious delivery to patients.
