Abstract
Objectives: To compare patient‐reported outcome measures and additional surgical outcomes after sinus floor elevation (SFE) with osseodensification (OD) versus lateral window (LW), both with simultaneous implant placement.Materials and Methods: Twenty participants requiring single‐implant rehabilitation with residual bone height (RBH) ≤4 mm were enrolled. Pain experience, quality of life (QoL) via the Oral Health Impact Profile‐14 (OHIP‐14), analgesics intake, and other symptoms were self‐reported for a week on a daily basis. Surgery duration, complications, and implant stability quotient at baseline (ISQ T0) and after 6 months (ISQ T6) were registered. Participants were followed up for 1 year.Results: From Day 0 (day of surgery) to Day 3, pain experience was significantly lower (p < 0.05) in the OD group. OHIP‐14 score was significantly lower (p < 0.05) in the OD group on all postoperative days, except on Day 5. Average analgesics intake was significantly lower (p < 0.001) in the OD group. Surgery mean duration was significantly higher (p < 0.001) in LW compared to OD (71.1 ± 10.4 vs. 32.9 ± 5.3 min). After osseointegration period, all implants were successfully restored with screw‐retained crowns.Conclusions: Within the limitations of this study, it can be concluded that OD and LW techniques were similarly effective in SFE with simultaneous implant placement when RBH ≤ 4 mm. However, OD significantly outperformed LW in pain experience, impact on self‐perceived QoL, surgery duration, postoperative edema, and analgesics intake.
