Trends in Computer-Aided Manufacturing in Prosthodontics: A Review of the Available Streams

“…Similarly, extraoral implant placement accuracy was 1.5 mm [139]. Farley reported that some stereolithography templates required intraoral relining to improve the fit on the adjacent teeth [28]; however, this discrepancy could not be related to manufacturing process. Instead, clinical variability such as soft tissue fit and compressibility and implant insertion in less dense bone may be the main source of the discrepancies [27, 139].…”

“…Overall, the accuracy of the surgical guides could be improved by fabricating them to fit the alveolar bone instead of soft tissue and by the use of fixation screws [27, 29]. Nevertheless, a split mouth clinical study revealed that the stereolithography guides allowed for implant placement closer to the planned position than conventionally fabricated guides [28]. …”

Computer‐supported implant planning and guided surgery: a narrative review

“…() described a specific drill design avoiding the use of drill keys or drills with different sheath diameters. Recent publications (Farley et al. ; Vercruyssen et al. ) have shown that the most significant error with guided surgery is made in vertical direction (depth).…”

“…• Recent publications (Farley et al 2013;Vercruyssen et al 2014a) have shown that the most significant error with guided surgery is made in vertical direction (depth). Horizontal inaccuracies are clearly less.…”

An adjustable, cast based, fully restrictive surgical guide

“…Fully restrictive guided surgery requires less skill than does freehand surgery and may improve the result. [14][15][16] A fully restrictive guide can be fabricated with one of 2 paths. The digital path uses cone-beam computed tomography (CBCT), dedicated software, and computeraided design/computer-aided manufacturing (CAD/ CAM) technologies.…”
