Aim of study. The purpose of our study was to assess the changes of the periimplant bone following the use of 3 bioactive implants systems to patients candidate to implant-prosthetic therapy. Materials and method. The study was performed on 30 patients (15 males, 15 females; aged between 35 and 48 years) divided in three study groups (9-Any Ridge, Megagen; 11- MIS Seven; 10- MIS C1). The investigated dental implant systems have different geometry, designs and bioactive surfaces. Each implant system was placed in 10 mandibular molars sites and 10 mandibular premolars sites that allowed the use of implants of at least 10mm length and 4 mm diameter. The occlusal loading was applied at 4-5 months after the implant placement. The peri-implant bone changes were measured by using software application and CBCT images at baseline (immediate post-implantation) and at 12 months follow-up after functional loading. Results. The measurements performed at baseline and at 12 months post-implantation revealed the absence of major differences between the investigated implant systems regarding the peri-implant bone resorption and osteo-density changes. The survival rate was 100% for all the investigated implants systems. Conclusions. The use of the bioactive implants systems Any Ridge (Megagen), MIS Seven and MIS C1 is associated with low vertical bone resorption and the increase of the peri-implant bone density as well as with the absence of implants failure at 12 months follow-up.
