Objectives: The purpose of the present study is to systematically review the accuracy of implant placement with mucosa-supported stereolithographic surgical guide and to find out what factors can influence the accuracy. Material and Methods: An electronic literature search was performed through the MEDLINE (PubMed) and EMBASE databases. The articles are including human studies published in English from October 2008 to October, 2017. From the examination of selected articles, deviations between virtual planning and actual implant placement were analysed regarding the global apical, global coronal, and angulation position. Results: A total of 119 articles were reviewed, and 6 of the most relevant articles that are suitable to the criteria were selected. The present data included 572 implants and 93 patients. The result in the present systematic review shows that mean apical global deviation ranges from 0.67 (SD 0.34) mm to 2.19 (SD 0.83) mm, mean coronal global deviation ranges from 0.6 (SD 0.25) mm to 1.68 (SD 0.25) mm and mean angular deviation - from 2.6° (SD 1.61°) to 4.67° (SD 2.68°). Conclusions: It’s clearly shown from most of the examined studies that the mucosa-supported stereolithographic surgical guide, showed not exceeding in apically 2.19 mm, in coronally 1.68 mm and in angular deviation 4.67°. Surgeons should be aware of the possible linear and angular deviations of the system. Accuracy can be influenced by bone density, mucosal thickness, surgical techniques, type of jaw, smoking habits and implant length. Further studies should be performed in order to find out which jaw can have better accuracy and how the experience can influence the accuracy.
