Abstract
PURPOSE OF REVIEW: CAD/CAM and 3D-printing are emerging manufacturing technologies in dentistry. In the field of alveolar ridge augmentation, graft customization utilizing these technologies can result in significant reduction of surgical time. A review of the literature on materials, techniques and applications of CAD/CAM and 3D-printing available for alveolar ridge augmentation was performed. RECENT FINDINGS: CAD/CAM applications for milling of customized block grafts of allogeneic, xenogeneic, and alloplastic origins have been reported, and currently only limited products are commercially available. 3D-printing applications are limited to alloplastic graft materials and containment shells, and have been mostly used in animal studies for optimizing biomaterials' properties. SUMMARY: While current data support the potential use of CAD/CAM and 3D-printing for graft customization for alveolar ridge augmentation procedures, additional research is needed on predictability and long-term stability of the grafted sites.
