With the development of computer and digital technology, the application of computer-aided technology has become a new trend in the field of oral implant. Computer-guided oral implant surgery has the advantages of being safer and more accurate than traditional implant surgery, and it can truly realize the concept of restoration-oriented implant. However, computer-guided oral implant surgery has various steps which cause deviations accumulation, so that some clinicians remain sceptical about the accuracy of the technology. Currently, due to the lack of a quantitative system for evaluating the accuracy of computer-guided oral implantation, the implant deviation in each step is still inconclusively in the stage of research and debate. The purpose of this paper is to summarize the advantages and disadvantages, research progress, accuracy and influencing factors of computer-guided oral implantation, aiming to provide a reference for improving implant accuracy and guiding clinical design and surgery.
With the intensification of population aging, the number of edentulous patients continues rising. Fixed implant prostheses have become the primary treatment for tooth loss due to their superior chewing efficiency and comfort. However, improper implant prosthetic design may lead to various mechanical and biological complications, and even result in implant failure. Therefore, systematically analyzing the mechanical factors that influence the outcomes of implant restoration and optimizing the design hold significant clinical importance. Finite element analysis, as an effective biomechanical research tool, can simulate the stress distribution in dental implants and bone tissues under different loading conditions, thereby providing a theoretical basis for optimizing implant restoration plans. This review focuses on the impact of factors including implant number, size, shape, inclination angle, framework design and different modeling assumptions on the stress distribution in edentulous implant, aiming to provide references for developing clinically rational implant restoration plans.
