Abstract | Objectives: compare the ISQ values obtained by the Osstell ISQ, screwing the Smarpeg directly
to the implant or to the new designed healing abutments of 2, 3.5 and 5 mm of height.
Methods: 60 rough surface implants were ... Objectives: compare the ISQ values obtained by the Osstell ISQ, screwing the Smarpeg directly to the implant or to the new designed healing abutments of 2, 3.5 and 5 mm of height. Methods: 60 rough surface implants were placed in 4 bovine ribs. 30 standard and 30 prototype implants were divided to group A and B, respectively. All were inserted with a torque of 30 N/ cm2, so that the rough/smooth interface was placed at bone crest level (the distance between the implants needed to be at least 4 mm). Primary stability was measured by resonance frequency analysis (RFA) with the Osstell ISQ transducer directly to the implant or over three Smartpeg screwed to the top of three different healing abutments of 2, 3.5 and 5 mm of height. Results: The mean ISQ of the prototype group is 73.9 ± 5.3 and of the standard one is 79.8 ± 3.7. The mean ISQ values according to where the Smartpeg is screwed to were 76.2 ± 4.47 and 75.69 ± 4.7 when the Smartpeg was screwed directly to the implant; 78.2 ± 5.78, 77.3 ± 5.90, 76.0 ± 5.90 when the transducer was screwed to the abutments of 2, 3.5 and 5 mm of height respectively. Conclusions: It may be concluded from the present investigation that similar ISQ values could be obtained measuring the RFA with the transducer screwed directly to the implant or to healing abutments of different heights, in an accurate and reproducible way.
