Intraoral radiographs were taken before and after implant placement, at the time of loading and after 11 to 32 months of loading (mean 16.4 months), to evaluate bone formation below the sinus membrane and marginal bone loss. Implant stability measurements (Osstell<jats:sup>TM<\/jats:sup>, Gothenburg, Sweden) were performed after implant installation and at abutment connection 5 months later. All implants were installed with the prosthetic platform level with the bone crest.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> No implant was lost giving a survival rate of 100% after a mean follow\u2010up time of 16.4 months. The average vertical bone height was 7.2\u2003\u00b1\u20031.5\u2003mm at placement and 10.0\u2003\u00b1\u20031.0\u2003mm after 11 to 32 months. The average increase of 2.8\u2003\u00b1\u20031.1\u2003mm was statistically significant. There was a statistically significant improvement in implant stability from 70.7\u2003\u00b1\u20039.2 implant stability quotient (ISQ) at placement to 76.7\u2003\u00b1\u20035.7 ISQ at abutment connection, 5 months later.
