The purpose of the study is to evaluate the survival rate of pterygoid implants compared to implants placed in different maxilla area and to settle as an alternative solution for the rehabilitation of the posterior maxilla atrophy. Studies that were included for this systematic review were selected using different database of references: PubMed Medline, Lilacs and Cochrane Library. Other journal platforms were also used for the research. Five articles met the strict inclusion/exclusion criteria of the 180 articles founded. This systematic review was registered on Prospero (CRD42023409706) and followed PRISMA statement. A total of 768 implants placed presented 97.43 % with a peak of 100 % of survival rate. Follow-up period varies from a minimum of 1 year to a maximum of six years. Pterygoid implants could be a valid alternative in patients presenting a posterior maxilla atrophy, but results should be interpreted cautiously due to the difficulty of the surgical technique. Further studies in the future should be taken in consideration to confirm the success rate of pterygoid implants since there is only one prospective RCT, potentially incorporating modern technologies such as guided surgery or navigated surgery could be a solution for the success of pterygoid implants, minimizing the risk and less dependent on the operator.
