Study models that have been articulated with a facebow transfer record and a maxillo‐mandibular relationship (MMR) record allow the clinician to measure and analyse occlusal relationships and spatial considerations, and to manufacture templates. The casts can be used to create a diagnostic set‐up of the proposed prosthesis using wax and/or denture teeth. This set‐up may then be transferred to the mouth to be evaluated, used as a radiographic guide or a surgical guide, and potentially transformed into a provisional restoration. More recently, the use of chairside intra‐oral scanning, DICOM data files from CBCT, and STL files from 3D optical scanning are merged to allow planning with interactive 3D software. The proposed virtual set‐up of teeth allows visualisation of the planned restoration in relation to the bone and soft tissue architecture. This allows analysis of the bony ridge in relation to the planned tooth position, so that the length, diameter, position, and alignment of implants can be determined accurately.
