Background Printing of templates for guided surgery represents an alternative to laboratory manufactured templates. Purpose To determine the technical accuracy of a virtually designed and printed surgical template for guided implant surgery based on a surface scan of a cast model using the co D iagnosti X TM software. Materials and Methods Cast models and the virtual planning data of nine patients receiving guided implant surgery with the co D iagnosti X software were analyzed. The original cast models were equipped with three titanium pins and scanned with a three‐dimensional scanner. The scans were uploaded in the co D iagnosti X software and the virtual surgical templates were designed including the sleeves at their original positions. After printing the surgical templates, the sleeve positions were determined by optical scanning, and deviations were calculated and compared with the virtual positions of the sleeves. Results The sleeves showed a mean three‐dimensional deviation of 0.22 mm (range: 0.07–0.38 mm) in the center of the sleeve top, 0.24 mm (range: 0.08–0.36 mm) in the center of the sleeve bases and a mean angular deviation of 1.5° (range: 0.4°–3.3°) compared with the virtual positions. Conclusions A high accuracy can be achieved using printed templates for guided implant surgery, by taking into account all sources of inaccuracies.
