In vitro assessment of primary stability of Straumann® implant designs.

Background: Primary implant stability (PS) is one of the main factors influencing implant survival rate. Several methods to determine the PS have been used, such as Periotest values (PVs) and resonance frequency analysis (RFA) with implant stability quotient (ISQ) values.

Purpose: The aim of this study was to compare different implant designs in regard to PS assessed by Periotest and RFA in vitro.
