The data of bone density and recordings of implant stability could increase the clinical success. Totally 62 dental implants P1H EHC were inserted; 29 in maxilla and 21 in mandible using SimPlant system in 12 females and 15 males, mean age 58 +-11 years. 11 times in maxilla and 3 times in mandible 3D surgical planning software without stereolithographic surgical templates were used. Clinical stabilities in Ncm and bone densities in Hounsfield Unites (HU) were determined at implant placement and only insertion torque at suprastructure fixation. Implant success rate after 1,7 years was 96,87%. The correlation coefficients between HU values outside the implant and insertion force during implant or suprastructure screwings were 0,48 and 0,13 respectively. The torsional forces for 60 implants at suprastructure fixation were >= 35 Ncm and 2 times in the group of 15-30 Ncm. Student's t-test demonstrated that there is the statistical significant difference between torsional forces for implants placement and screwings forces at suprastructure fixations.
