Abstract
Passive fit of implant frameworks is an important factor for the longevity of this type of rehabilitation. Ill-fitted frameworks generate stresses that are transmitted to the retention system, implants and peri-implant bone tissue. This study aims to verify the role of screw type (conventional (CS) or coated with a carbon layer (LS)) and bar material (Co-Cr, Ni-Cr, Ti cp) in misfit compen…
