<abstract abstract-type="main" id="clr12460-abs-0001"> <title>Abstract</title> <sec id="clr12460-sec-0001" sec-type="section"> <title>Aim</title> <p>To assess the accuracy of guided surgery compared with mental navigation or the use of a pilot‐drill template in fully edentulous patients.</p> </sec> <sec id="clr12460-sec-0002" sec-type="section"> <title>Material and methods</title> <p>Sixty consecutive patients (72 jaws), requiring four to six implants (maxilla or mandible), were randomly assigned to one of the following treatment modalities: Materialise Universal<sup>®</sup> mucosa, Materialise Universal<sup>®</sup> bone, Facilitate<sup>™</sup> mucosa, Facilitate<sup>™</sup> bone, mental navigation, or a pilot‐drill template. Accuracy was assessed by matching the planning CT with a postoperative CBCT. Deviations were registered in a vertical (depth) and horizontal (lateral) plane. The latter further subdivided into BL (bucco‐lingual) and MD (mesio‐distal) deviations.</p> </sec> <sec id="clr12460-sec-0003" sec-type="section"> <title>Results</title> <p>The overall mean vertical deviation for the guided surgery groups was 0.9 mm ± 0.8 (range: 0.0–3.7) and 0.9 mm ± 0.6 (range: 0.0–2.9) in a horizontal direction. For the non‐guided groups, this was 1.7 mm ± 1.3 (range: 0.0–6.4) and 2.1 mm ± 1.4 (range 0.0–8.5), respectively (<italic>P</italic> < 0.05). The overall mean deviation for the guided surgery groups in MD direction was 0.6 mm ± 0.5 (range: 0.0–2.5) and 0.5 mm ± 0.5 (range: 0.0–2.9) in BL direction. For the non‐guided groups, this was 1.8 mm ± 1.4 (range: 0.0–8.3) and 0.7 mm ± 0.6 (range 0.0–2.9), respectively. The deviation in MD direction was significantly higher in the non‐guided groups (<italic>P</italic> = 0.0002).</p> </sec> <sec id="clr12460-sec-0004" sec-type="section"> <title>Conclusion</title> <p>The most important inaccuracy with guided surgery is in vertical direction (depth). The inaccuracy in MD or BL direction is clearly less. For non‐guided surgery, the inaccuracy is significantly higher.</p> </sec> </abstract>
