Mode of Retention of Removable Implant Prosthesis

Implant overdentures may be retained using bar and clip attachment systems and/or individual, free-standing abutment-based attachments. Freestanding attachments include balls, magnets, resilient stud attachments, such as the Locator system (Zest Dental Solutions), Locator R-Tx system (Zest Dental Solutions) and ERA (Sterngold), and non-resilient stud attachments such as Ankylos Syncone (Dentsply International).31
