This research aimed to synthesize and evaluate current scientific findings concerning both clinical outcomes and laboratory investigations on fiber-reinforced posts, emphasizing the cementation procedures used in restorative dentistry. A systematic search of the PubMed/Medline database was conducted for publications from 2010 to 2023. The search combined the terms “fiber post,” “intra-coronal post,” “post cementation,” and “post length.” Articles were first screened by title and abstract; those meeting inclusion standards were fully reviewed. References from included studies were also checked to identify additional relevant works.
Out of 135 initial publications, 90 met the inclusion requirements based on their abstracts, and 50 were retained after full-text evaluation. Further relevant papers from citations were incorporated, resulting in 57 studies in total. Data from both in vitro and clinical research suggest that fiber posts exhibit a similar survival rate to prefabricated or cast metal posts, with most failures attributed to loss of retention. Posts shorter than two-thirds of the root length performed well when a ferrule effect was present, which also increased the lifespan of restored teeth. Additionally, surface conditioning of fiber posts and adhesive bonding techniques contributed to improved clinical durability and long-term success of post-retained restorations.
