Initially proposed in 1986, implant success criteria—concerning marginal bone loss and other factors—are still widely referred to as the "gold standard" for implant success today. However, these criteria are incorrect for the wide range of implant systems, as shown by the current abundance of data on marginal bone loss and a better understanding of bone and soft tissue behaviour around the implant neck and body. This article's goal is to review some of the pertinent research on cumulative survival rate of dental implants of varied dimensions. 5 articles of different studies from 2007 to 2021 with follow up period of more than 3 years to analyse different length and diameter to evaluate survival rate of dental implants. Results states that These included studies consist of 5 clinical studies out which 3 were retrospective. Out of the included studies, 3 included studies have long follow-up of more than 3 years. 4 studies only included implant diameter. In included RCT both implant length and diameter were included. Cumulative survival rate was found to be 98.7%.
