Advanced Guidelines in Implant Placement Surgery: A Systematic Review Study

Introduction: Proper placement of dental implants is essential to prevent damage to vital structures, provide optimal prosthetics, and ensure a successful long-term outcome. While previous studies have sporadically addressed individual advanced surgical guidelines, this systematic review aimed to uniquely synthesize and compare the latest evidence on multiple advanced implant placement techniques from ۲۰۱۹ to ۲۰۲۴, providing clinicians with comprehensive guidance on their relative advantages and accuracy metrics. Methods: In this systematic review, major international databases, such as PubMed, WOS, Scopus, and the 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 ۲۰۱۹ to March ۲۰۲۴. Two researchers conducted the search using relevant keywords and their combinations. Results: Overall, ۶۶۱ articles were identified in the initial search. After eliminating duplicates and reviewing titles, abstracts, and inclusion/exclusion criteria, a total of ۱۳ 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 (in both static and dynamic methods) and augmented reality-based navigation with cone-beam computed tomography. The success rates of these advanced implant placement guidelines were reported through evaluating their accuracy metrics (assessing hex deviation, angular deviation, crown positioning, and implant angle). In all the 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 this review, 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 was associated with higher accuracy in implant placements. Given that implant placement surgery can have long-term clinical implications, it is recommended that researchers focus on this type of surgery in the future.
