The posterior region of maxilla presents a poor bone quality. Therefore, different drilling protocols have been proposed to obtain an adequate primary stability in dental implant installation.The aim of this study was to compare the effect on primary stability of dental implant installed in poor bone quality analyzed by Micro-CT, using three types of drilling protocols. 30 Fresh porcine bone ribs fragments of 3 cm each one were analyzed using Micro-CT. Thirty dental implants (3,75 x 9 mm Titamax Cone morse EX, Neodent®) were installed individually using three different drilling protocols- Group 1 Manufacturer drilling protocol (conventional drilling method)+ Group 2 Under preparation and Group 3- Stepped osteotomy. Drilling was performed using a surgical hand-piece speed reducer, which was linked to an Instrom 4411 mechanical testing machine. To assess primary stability, the final insertion torque values and Implant stability quotient (ISQ) in two directions- Mesio-distal (MD) and Posterior-anterior (PA) were registered. Statistical tests included One-way ANOVA with Tukey post-hoc tests with significance level of 5%. Pearson and Spearman correlations were also used.Group 3 obtained the highest values of final insertion torque values, but it was not statistical significant. In regards to ISQ-PA values, group 1 had higher values than group 3, with significant statistical difference (p=0.038). Pearson and Spearman's correlations do not indicate a strong correlation between final insertion torque values and MD-ISQ and PA-ISQ.The Stepped osteotomy showed better values of final insertion torque values, the manufacturer protocol drilling provided and adequate ISQ values and it was not possible to correlate final insertion torque values and ISQ values.
