N2 - Cone-Beam Computerized Tomography (CBCT) manages to determine the bone density in Hounsfield Units (HU). Implant stability may be assessed by the implant torque test or radio-frequency analysis (RFA). 28 patients were gathered and the sample was composed of 79 implants (Anyridge, Megagena). Bone density was assessed by CBCT. Implant torque was determined during implant surgery. RFA was expressed by the implant stability quotient (ISQ), measured by OsstellR. Spearman correlation test found significant correlations in the three associations. On the one hand, bone density determined correlation values were rs = 0,322 (p =0,01) with insertion torque, and rs =0,296 (p =0,005) with ISQ; on the other hand, the ISQ proved to have a correlation value of rs <0,834 (p <0,001) with the implant torque. Upper and lower jaw have shown statistically significant differences between bone density, torque and ISQ (p <0.01). Pre-operatory bone density assessment appears to predict the implant primary stability coordinates.
