16 I I case report _ guided surgery _Introduction Restoration-driven implant placement is a key factor for successful implant therapy. In this context, Computer-assisted Implant Surgery (CAIS) offers an additional instrument for treatment planning, surgical placement and prosthetic reha- bilitation in an interdisciplinary team approach. The continuous technological progress in both the computer-based development and the den- tal manufacturing process ensures new opportuni- ties in the clinical workflow. DWOS, in association with Straumann, offers a powerful combination of CAIS with the established GonyX System. In addi- tion, a fully digital pathway in a model-free ap- proach or a combination of these workflows is now possible. This case presentation displays insights into the currentprocessesofCAISwithanoutlookonfuture improvements in the digital implant workflow. _Interdisciplinary Planning CoDiagnostiX ensures the planning of the im- plant position using Cone Beam Computed Tomo- graphy (CBCT) with DICOM data (Digital Imaging and Communications in Medicine) and the subse- quent transfer of the virtual situation into reality with an interdisciplinary team approach including the restorative dentist, the implant surgeon and the dental technologist. The conventional workflow includes the fab- rication of a dental set-up, a radiographic template and the secondary adaptation to a surgical tem- plate. Here, the fully digital process represents a further development: computer-assisted planning of the implant position by means of a virtually con- structedprostheticset-upandon-screendesigning of an implant-guided template. The number of op- erational steps is shortened significantly compared to the conventional workflow. Moreover, costly and time-intensive prepara- tions can be avoided for the patient in advance of the CBCT. In addition, existing 3-D radiographic images should already be used, if possible.
