Methods:130 self-tapping implants, 4 mm diameter and 15 mm length (3i Implant Innovations, EUA), were distributed in two groups where each one was composed of 13 bovine bone block and 13 rigid polyurethane block. The samples were cut so that the implants were distributed that in G1 and G2 the exposed thirds were below the crest of material and in G4 and G5 the exposed thirds were above the crest of material. In G3 the implants were entirely within the material.
Results:G1, G2 e G3 showed no statistically significant difference in both materials but this difference was present when they were compared with G4 and G5 (p<0,05). ISQ values did not correlate to insertion torque values.
Conclusion:Osstell showed more sensitive in detecting alterations in the cervical region of the bone-implant complex, in spite of the fact that it may not be a useful method to detect problems in the apical region.
