However, for possible slipping of the cement below the mucosal margin, its thorough removal poses some issues. The objective of this study was to evaluate the presence of submucosal cement residues in patients with peri\u2010implant disease by endoscopic visualization and to investigate the potential correlation between the pathological scenario and the spatial position of cement residues.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The study sample comprised 46 consecutive patients exhibiting clinical and radiographic signs of peri\u2010implant disease around cement\u2010retained crowns. When at first visit bleeding on probing was the only pathological sign, the area was debrided and then treated with antiseptic agents for 30 days. Only those patients for whom bleeding was still found at re\u2010evaluation were included in the study. All implants were therefore endoscopically evaluated to identify possible submucosal cement residues. For all implants showing residual cement, the spatial position of the residual cement was recorded with respect to predefined points.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Cement residues were detected in 80.4% of the patients and were predominantly located in the vestibular and lingual areas (88%). Analysis of the distances between the apical portion of the residues and anatomical landmarks revealed significant differences between mucositis and peri\u2010implantitis patients (\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.001). In cases of peri\u2010implantitis, the cement residue was more apically located than in mucositis.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The presence of cement residue was associated with peri\u2010implant disorders in the majority of patients. A potential correlation between the position of residues and the peri\u2010implant disease scenario is here suggested.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Plain Language Summary<\/jats:title>\n                    <jats:p>A common method for fixing the crown on the dental implant is the use of specific cements. However, these products can slip below the gum line resulting in difficulties in their removal, which could cause peri\u2010implant disease. This study aimed to evaluate the presence and location of residual cement hidden under the gums in patients with peri\u2010implant disease, characterized by symptoms such as bleeding gums and, in some cases, bone loss around the dental implant. Using a small fiber\u2010optic camera (endoscope), 46 patients were examined for any cement residue under the gums. The study showed that more than 80% of patients had cement residues, especially in the areas facing the cheeks and tongue. It was also found that in patients with a more severe form of inflammation (peri\u2010implantitis), the cement was placed deeper than in those with a milder form (mucositis). This confirms that residual cement is common in patients with peri\u2010implant disease, but also suggests that its location could influence the severity of the pathological manifestation. This finding highlights the importance of carefully removing all cement to prevent such complications.<\/jats:p>\n
