Finite element analysis of narrow dental implants

Aug 9, 2020 by in Dental Materials Comments Off on Finite element analysis of narrow dental implants

Abstract Narrow-diameter implants (NDIs) traditionally have been associated to higher rates of failure in comparison with regular-diameter implants (RDIs) and wide-diameter implants (WDIs), since they generate a more unfavorable stress…
