Maxillary sinus lifting is necessary when there are no dimensions required for implant installation. The Summers osteotome technique elevates the maxillary sinus floor concurrently with the preparation of the implant receiving bed. In order to improve the prognosis of treatment, the osseodensification technique brings the premise of elevating the maxillary sinus while preparing the bone bed, but with an increase in the surrounding bone density. Primary stability is described in the literature as an essential prerequisite for osseointegration. The purpose of this research is to compare the primary stability between Summers' osteotome and osseodensification techniques. Eight patients were selected, who received in each hemiarchy of the maxilla one of the groups in this study, a technique with Summers osteotomes (Control Group) and by osseodensification (Test Group). Twenty-nine implants were installed divided into the two groups. After the implants were installed, their primary stability was measured using the Torque and the Occlusal and Lateral Implant Stability Coefficient (ISQ) measured in the experimental times of the immediate postoperative study (T0) and three months (T3). The results obtained demonstrate that the implants installed by the osseodensification technique have higher torque and ISQ in both experimental times (p <0.05). We can conclude that the osseodensification technique favors better primary stability than the breast lift technique using Summers osteotomes.
