The aim of this study was to analyze studies that have evaluated survival rates of osseointegrated implants and identify if there was any difference between the results observed in studies conduct in Europa and Brazil. A Systematic review was performed using two search strategies on MEDLINE/PUBMED, Embase and Scopus databases to identify eligible studies published up to February 2020. Twenty-three studies that met the inclusion criteria were selected for data extraction, which revealed implant survival rates ranging from 83.3% to 100% in studies conducted in Brazil (except for one study that presented a survival rate of 56.6% due to application of immediate loading in implants presenting low primary stability), and a rage of 83.2% to 100% in the European studies. Regarding adverse events, bone loss was the most reported one in the Brazilian studies, whereas bone loss and prothesis fracture are the most present in the studies conducted in Europe. Few differences were found between the two groups of studies with respect to follow-up period and patient´s mean age. Therefore, our study suggests that outcomes of studies on osseointegrated dental implants conducted in Brazil can be extended to the European population, and vice-versa.
