Abstract
Background: Proper placement of dental implants is essential to prevent damage to vital structures, provide optimal prosthetics, and ensure a successful long-term outcome. Achieving this goal requires the use of advanced guidelines in dental implant surgery, which assist in diagnosis, treatment planning, and determining the appropriate angle and position for dental implants. Therefore, this study was conducted to systematically review the latest advanced guidelines in implant placement surgery. Methods: In this systematic review, major international databases such as PubMed, ISI, Scopus, UpToDate, and Cochrane Library, were utilized to evaluate published articles related to advanced guidelines in implant placement surgery. The search focused on In Vitro Studies, randomized controlled clinical trials, and cohort studies published in English from 2019 to March 2024. Two researchers conducted the search using relevant keywords and their combinations. Results: At the initial search, 661 articles were identified; after eliminating duplicates and reviewing titles, abstracts, and inclusion/exclusion criteria, a total of 13 articles were selected for inclusion in the study. Based on the results of the reviewed studies, the latest advanced guidelines in implant placement surgery include computer-assisted implant surgery (CAIS) (in both static and dynamic methods) and augmented reality-based navigation with cone-beam computed tomography (CBCT). The success rates of these advanced implant placement guidelines were reported by evaluating their accuracy metrics (assessing hex deviation, angular deviation, crown positioning, and implant angle). In all mentioned guidelines, the accuracy of implant placement was found to be superior to that of free-hand implant placement guidelines. Conclusion: According to the results of the present systematic review study, although the accuracy of the newly introduced advanced guidelines was higher than that of free-hand guidelines, there was no clear evidence indicating which advanced surgical guideline is associated with higher accuracy in implant placements. Since implant placement surgery can have long-term clinical implications, further similar studies are recommended.
