Application of digital implant guide plate in oral implant restoration

Abstract

Digital implant guides have enabled "repair⁃oriented" implant restoration to become a reality by allowing an implant to be designed for an ideal site, maximizing the use of existing alveolar bone, and increasing the predictabili⁃ ty of the restorative effect. This paper reviews the classification of digital guides and the related factors affecting the ac⁃ curacy of digital guides to provide a reference for clinical doctors in practical applications. Digital guides can be divid⁃ ed into the categories of mucosal support, bone support, dental support and mixed support according to the retention mode. The manufacture and use of digital implant guides involve a series of processes, such as data acquisition, design and manufacture of the implant guide, and guided surgery. The accuracy of digital implant guides depends on all accu⁃ mulated and interactive errors involved in the process from data acquisition to surgery. According to the process of guide plate fabrication and implant placement, errors in all aspects can be reduced to improve the accuracy of guide plate application.
