In Vitro Cyclic Dislodging Test on Retentive Force of Two Types of Female Parts of SFI-Bar

I mplant overdentures have been proven to be superior to conventional dentures in restoring the edentulous mandible.1’2 Compared with various unsplinted attachments [eg, Locator attachments, ball attachments], bar-clip attachments can transmit vertical loads more effectively to supporting implants.3 Stress-Free Implant Bar [SFI-Bar, Cendres+Metaux] is a modular system that connects implants with no soldered or laser-welded joints, and this allows fabrication of a passive-fit bar and clip system on two or more implants.
