Digital planning and bone regenerative technologies: A narrative review

Abstract Objectives The aim of this narrative review was to explore the application of digital technologies (DT) for the simplification and improvement of bone augmentation procedures in advanced implant dentistry. Material and methods A search on electronic databases was performed to identify systematic reviews, meta‐analyses, randomized and non‐randomized controlled trials, prospective/retrospective case series, and case reports related to the application of DT in advanced implant dentistry. Results Seventy‐nine articles were included. Potential fields of application of DT are the following: 1) the use of intra‐oral scanners for the definition of soft tissue profile and the residual dentition; 2) the use of dental lab CAD (computer‐aided design) software to create a digital wax‐up replicating the ideal ridge and tooth morphology; 3) the matching of STL (Standard Triangulation Language) files with DICOM (DIgital COmmunication in Medicine) files from CBCTs with a dedicated software; 4) the production of stereolithographic 3D models reproducing the jaws and the bone defects; 5) the creation of surgical templates to guide implant placement and augmentation procedures; 6) the production of customized meshes for bone regeneration; and 7) the use of static or dynamic computer‐aided implant placement. Conclusions Results from this narrative review seem to demonstrate that the use of a partially or fully digital workflow can be successfully used also in advanced implant dentistry. However, the number of studies (in particular RCTs) focused on the use of a fully digital workflow in advanced implant dentistry is still limited and more studies are needed to properly evaluate the potentials of DT.
