Compared to conventional complete dentures implant-supported overdenture prostheses used in completely edentulous patients give more successful results in the long term. Compared to conventional complete dentures, it has superior features in terms of retention, stability, chewing performance and aesthetics. This situation increases patient satisfaction and quality of life. Various retention systems are used to provide retention in implant-supported overdenture prostheses. In these systems, implants are splinted to each other or used as individual attachments. Splinted attachments are used in cases where resection is made in soft tissues or bone, oval crests and in cases where retention and stability are required in excessively resorbed crests by connecting to each other with the help of bar attachment. Non-splinting attachments are independent attachments on implants. The patient’s vertical bone loss, expectation, oral hygiene, retention value of the prosthesis, and the position of the implants in the arch should be considered when choosing retention systems. The purpose of this review is to summarize the features, usage areas, advantages and disadvantages of single attachment systems used today.
