| Abstract: | The aim of this study was to assess the primary stability of dental implants by resonance frequency analysis (RFA) using the Osstell? and Osstell Mentor? devices and to investigate the reproducibility and comparability of the results obtained with these devices. Twenty‐four Straumann implants (Straumann AG, Basel, Switzerland) were placed in the anterior mandible of 12 fresh edentulous human cadaver mandibles. The implant stability quotients (ISQs) were measured with the Osstell? and Osstell Mentor? when implants were inserted at 50% of their length and following their complete insertion. The Osstell? device measured lower scores compared with the Osstell Mentor?. This was significant for the full position (mean difference = 9·9), t (11) = 7·4, P < 0·001 and for the halfway position (mean difference = 5·9), t (11) = 2·41, P = 0·03. In con‐clusion, the Osstell? produced relatively lower ISQ scores than the Osstell Mentor?. |
