The mechanical failure of a dental implant is clinically related to a prosthetic overload dissipated on the fixture/abutment complex. The aim of this investigation was to evaluate the fracture strength of two vs three narrow-diameter dental implant configurations for screw-retained bars. Different configurations of screw-retained bars on two narrow-diameter dental implants (Group I) and screw-retained bars on three narrow-diameter dental implants (Group II) were tested under a static fracture loading. A total of 20 specimens, 10 for each group were evaluated. The fracture loading point was significatively higher in Group I (p<0.05). The experimental groups reported high levels of fracture strength under loading that encourages the clinical application of screw-retained bars supported by multiple narrow-diameter implants.

Abstract

The mechanical failure of a dental implant is clinically related to a prosthetic overload dissipated on the fixture/abutment complex. The aim of this investigation was to evaluate the fracture strength of two vs three narrow-diameter dental implant configurations for screw-retained bars. Different configurations of screw-retained bars on two narrow-diameter dental implants (Group I) and screw-retained bars on three narrow-diameter dental implants (Group II) were tested under a static fracture loading. A total of 20 specimens, 10 for each group were evaluated. The fracture loading point was significatively higher in Group I (p<0.05). The experimental groups reported high levels of fracture strength under loading that encourages the clinical application of screw-retained bars supported by multiple narrow-diameter implants.
