Book excerpt: BACKGROUND: Resonance frequency analysis (RFA) is a simple, practical, reproducible, clinically feasible and non-invasive method that allows to safely assess the degree of stiffness that the implant is within the bone structure. AIM: According to the applied methodology, the aim of this clinical study was to perform a research to evaluate the stability of two different types of implants, with resonance frequency analysis (RFA). METHODS AND MATERIALS: This clinical research was approved by the ethical committee (Plataforma Brasil) under the number CAEE 54726816.6.0000.5374. Patients were submitted to conventional dental implant surgery with installation of two implants, Straumannu2019s, Bone Level Tapered (BLT) 4x8mm and SINu2019s Unitite 4x8,5mm. Each patient received two implants, one from each brand, with their respective healing abutments. The stability of the implants (ISQ) was measured by the Osstell apparatus. A torque of 10Ncm was applied to the smartpegs. The stability of the implants was measured at the time of surgery, four, six and eight weeks post-surgery. At each stage, three measurements were taken and a mean (mean ISQ) was obtained for each implant. RESULTS: Each group (SINu00ae and Straumannu00ae) was treated, separately, with ANOVA and the differences found identified by Tukey-Kramer multiple comparisons test. The Straumann implants show no statically difference in the ISQ values for all measurements. The SIN group showed only a statistically lower ISQ value in the 4 week. The two groups were compared in all stages with a paired t-test. The ISQ values u200bu200bfor the Straumann groups were statistically higher in all stages (P
