Article history: Objectives: compare the ISQ values obtained by the Osstell ISQ, screwing the Smarpeg directly
Received 7 October 2016 to the implant or to the new designed healing abutments of 2, 3.5 and 5 mm of height.
Accepted 17 March 2017 Methods: 60 rough surface implants were placed in 4 bovine ribs. 30 standard and 30 prototype
Available online 16 May 2017 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
Keywords: the implants needed to be at least 4 mm). Primary stability was measured by resonance
Abutment design frequency analysis (RFA) with the Osstell ISQ transducer directly to the implant or over three
Bone implant interface Smartpeg screwed to the top of three different healing abutments of 2, 3.5 and 5 mm of height.
Dental implants Results: The mean ISQ of the prototype group is 73.9 ± 5.3 and of the standard one is 79.8 ± 3.7.
Osseointegration 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. (Rev Port Esto-
