Background Implant-supported overdenture is one of the most predictable treatment options used to restore completely edentulous patients. It offers a retentive and a stable prosthesis resulting in higher patient satisfaction and improved oral functions. Various attachment systems are actively used to anchor the overdentures to the underlying implants, but differences have been reported between them in terms of patient satisfaction, prosthesis retention, and attachment maintenance. Objectives To compare the effectiveness of different attachment systems of implant-supported overdentures for completely edentulous patients to improve patient satisfaction and enhance prosthesis retention, and attachment maintenance. Search methods We searched the Cochrane Oral Health Group Trial register (13 November 2014), Cochrane Central Register of Controlled Trials (The Cochrane Library 2014, Issue 11), MEDLINE ( January 1966 to 13 November 2014) and the WHO International Clinical Trial Registry Platform (13 November 2014). We handsearched citation lists of relevant publications. We did not apply any language or date restrictions. Selection criteria Randomised controlled trials (RCTs) of the different attachment systems used to retain the implant-supported overdentures in completely edentulous patients. Data collection and analysis Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked for accuracy. We have expressed results as risk ratio (RR) or mean differences (MD), together with their 95% confidence intervals (CI). The primary outcome measures were patient satisfaction, prosthesis retention, and attachment maintenancetulous patients to improve patient satisfaction and prosthesis retention, and attachment maintenance
