Computer-Guided Implant Surgery, an Overview from the Diagnosis to the Rehabilitation

“…This protocol allows simplification of the procedure for clinical staff and for the patient. Because it is a minimally invasive procedure, the technique consumes less time and offers less postoperative morbidity, less bleeding and a high degree of patient satisfaction (8,11,12,13). Clinical studies have shown that the success rate of implants in guided surgery is very similar to the conventional technique, with a high absolute survival rate around 95% (12).…”

Virtual Planning for Dental Implant Placement Using Guided Surgery

“…interocclusal registration with addition or condensation silicone for guidance during CT scanning; f. occlusal CT view of guide and interocclusal record; g. isolated scan of guide (for flapless procedures) (Parel & Triplett, 2004;Balshi et al, 2006;Marchack, 2007;Sanna et al, 2007;Van Assche et al, 2007). CT slices acquired in the DICOM file format must be converted with the aid of a specific software package prior to manipulation and reformatting into 3D images.…”

“…CT slices acquired in the DICOM file format must be converted with the aid of a specific software package prior to manipulation and reformatting into 3D images. During this process, the isolated radiographic guide scan is superimposed onto its occlusal view, using the radiopaque points as landmarks (Parel & Triplett, 2004;Balshi et al, 2006;Marchack, 2007;Sanna et al, 2007;Van Assche et al, 2007). The threshold for the case is also defined during this stage (Souza et al, 2003).…”

“…These applications provide axial, panoramic, and three-dimensional reconstructions of CT slices (Marchack, 2007;Sanna et al, 2007;Van Assche et al, 2007). They also enable manipulation of the panoramic reconstruction curve on the axial plane, providing orthogonal slices for assessment of alveolar ridge thickness in the vestibulolingual or vestibulopalatal direction (Parel & Triplett, 2004;Sanna et al, 2007;Van Assche et al, 2007). Virtual planning gives implantologists the ability to choose the precise location, orientation, and dimensions of implants, abutments and other fixtures.…”

“…The final stage of planning consists of defining the sites for placement of two or more anchor pins for the surgical guide, which are inserted through the vestibular aspect of the guide, between the implants (Balshi et al, 2006;Marchack, 2007;Sanna et al, 2007). After planning is complete, files are sent to a medical prototyping facility, where they will be converted into an appropriate format for prototype fabrication (Parel & Triplett, 2004;Marchack, 2007;Sanna et al, 2007;Van Assche et al, 2007). With implant positions established, a surgical guide is designed on the basis of the virtual model and sent to the prototyping station, where it is then fabricated (Lal et al, 2006).…”
