Radiographic assessment of vertical bone level changes (primary outcome), clinical status of peri\u2010implant tissues, changes in soft tissues margin, papilla filling, patient\u2010related outcomes and adverse events were assessed 6 and 12\u00a0months after loading.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      60 implants were placed in 40 patients, replacing single or multiple absent teeth. One implant was lost 1\u00a0week after insertion (overall survival rate: 98.3%). A statistically significant greater bone resorption from surgery to 6\u00a0months post\u2010loading was observed for those implants subjected to abutment change (control group: \u22121.24\u00a0\u00b1\u00a00.79\u00a0mm; test group: \u22120.61\u00a0\u00b1\u00a00.40\u00a0mm;\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0=\u00a00.028). Periodontal clinical parameters and patient\u2010related outcomes, however, did not demonstrate significant differences between groups at any time point. A significant increase in papilla height was observed from loading to 12\u00a0months in all implants (control group: 1.17\u00a0\u00b1\u00a01.47\u00a0mm; test group: 0.98\u00a0\u00b1\u00a00.89\u00a0mm)
