PESS was performed with PRF as the sole grafting material. LSFE was performed using deproteinised bovine bone matrix. Patient\u2010reported outcomes were recorded on a visual analogue scale (VAS\u2010pain) and visual rating scale (VRS\u2010swelling and VRS\u2010willingness). Peri\u2010implant bone height (PBH), bone mineral density (BMD) and sinus grafting remodelling index were measured using CBCT immediately postoperatively and 3rd, 6th and 18th months post\u2010surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The study population consisted of 20 patients in each group. The RBH of two groups averaged 3.35\u00a0\u00b1\u00a00.79\u00a0mm and 2.92\u00a0\u00b1\u00a00.63\u00a0mm with no significant difference (<jats:italic>p<\/jats:italic>\u00a0&gt;\u00a0.05). VAS\u2010pain was 18.0 (IR 15.0\u201322.5) and 35.0 (IR 32.5\u201337.0) in the PESS and LSFE groups, respectively (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.01). VAS\u2010pain decreased with time in both groups. VRS\u2010swelling was lower in the PESS group than LSFE group. VRS\u2010willingness was higher in the PESS group than LSFE group (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.01). At 18\u00a0months post\u2010surgery, the marginal bone loss was 0.60\u00a0\u00b1\u00a00.25\u00a0mm and 0.69\u00a0\u00b1\u00a00.35\u00a0mm in the two groups with no significant difference (<jats:italic>p<\/jats:italic>\u00a0=\u00a0.52).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Within the limitations of this study, PESS was associated with lower postoperative morbidity and was more tolerable than LSFE.
