With the increasing development of digital technologies，digital surgical templates have been widely used in stomatology. However，the accuracy of digital surgical templates is always a consideration for many researchers and dentists. This article analyzed the factors affecting the accuracy of digital surgical templates and found that errors arise from six factors，including the design and manufacture of the templates，implant guide support，implant systems and guide systems，implant length，bone density and the clinical experience of the operator；this literature review aims to reduce or eliminate human factors and improve accuracy，objectivity and security in implant placement.
