SFI Bars and Milled Bars Supporting Mandibular Overdentures. Three-year Randomized Clinical Trial

SFI bar was sectioned and adjusted on the model for more convenience and to save the time of the appointment. The bar (Cendres Metaux, Switzerland) abutments were screwed to the implant analogues.

bar abutments were attached to the analogues and scan bodies were threaded into the bar abutments. The cast was scanned using a lab scanner (Ceramill, Amann Girrbach, Germany). The milled bar was selected from the software (Exocad DentalCAD) and designed digitally to connect the implants.
