Abstract

In conventional bar- and clip-retained overdentures, all errors during impression making and cast fabrication result in non-passive fit of bars. SFI bar is prefabricated and assembled in the patient's mouth without the use of soldering, laser welding or conventional bonding techniques, thus reducing stress transmission to, bone loss around the implants and leading to fewer errors and lower costs. A clinical case will be presented below to demonstrate the use of the SFI Bar (Stress Free on Implant Bar) to restore an severe atrophy edentulous maxilla. In this case, no lateral stress could be applied to the implants due to the telescopic design of the bar joints. However, periodic recall check is necessary and long-term clinical results are required.
