Abstract: In recent years, the rapid development of digital technology leads to great upgrading in dental technology and comprehensive changes in dental implantology. Dental implant placement through a digital implant surgical guide system brings many advantages, like keeping them minimally invasive, the reduction in operative times, and, mainly, a more safe application. However, the postoperative position assisted by the digital implant surgical guide still has a certain deviation from the ideal position of preoperative design. In the entire process of computer-assisted, digital implant guide surgery, from preoperative data collection, guide plate design, guide plate production and printing, to the operation process, multiple links may have an impact on the accuracy of implantation. The registration of digital impression data and CBCT in the design of digital implant surgical guides is considered to be one of the key technologies affecting the accuracy of static surgical guides. This review article introduces the current research status and error sources of registration technology of digital impression and CBCT, to provide beneficial references for oral clinical and basic research.
