Background Very few controlled studies have compared short and long implants placed with appropriate sinus floor elevation techniques. Purpose To compare the 2‐year outcomes of 6.5‐mm hydrophilic implants placed with osteotome sinus floor elevation (OSFE) and standard implants placed with lateral sinus floor elevation in patients with a severely atrophic posterior maxilla. Materials and Methods Thirty‐eight patients with a residual bone height of 4–5 mm were randomized to receive one of the two above‐mentioned treatments. Intra‐ and postoperative complications were recorded. The implant survival rate, peri‐implant bone level, and periapical endosinus bone gain were assessed. Results Of the 80 inserted implants, one in the long implant group failed because of abscess formation. The peri‐implant bone level change (0.35 ± 0.60 mm vs 0.40 ± 0.71 mm) was not significantly different between the two groups. The endosinus bone gain was 2.94 ± 0.81 mm and 10.19 ± 0.95 mm in the short and long implant groups, respectively. No serious adverse events related to implant surgery were recorded. Conclusions The results suggest that the placement of 6.5‐mm short implants with OSFE is an effective alternative for the rehabilitation of a severely atrophic posterior maxilla.
