Abstract: In recent years，digital technology has gradually become a hot spot in the field of stomatology，which has been more and more widely used in clinical practice. It is believed that it will significantly change the future mode of oral diagnosis and treatment. Although the traditional implant impression technology has been relatively mature，there are still shortcomings such as long time consumed，strong sense of foreign body in patients，and complex operation process. The oral scanning technology may make up for these shortcomings. However，the accuracy，scope of application and influencing factors of oral scanning technology still need to be further studied. This article provides a review of the principles and accuracy of digital intraoral scanning technology，as well as the accuracy analysis methods and results of its application in oral implant restoration. It provides a reference for further clinical research on the accuracy of digital intraoral scanning and helps clinicians choose suitable intraoral scanners.
