Data collection included medical and dental history, full\u2010mouth clinical examination, and periapical radiographs. Moderate\/severe peri\u2010implantitis was diagnosed based on bone loss (direct criterion, when available) or bone level (indirect criterion) \u2265\u20092\u2009mm and the presence of bleeding\/suppuration. PISTD was defined as mucosal dehiscence on the buccal aspect of at least one implant site. Multilevel, multivariable logistic regression models were applied to identify factors associated with moderate\/severe peri\u2010implantitis and buccal PISTD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of the 397 patients contacted, 146 were included (mean age 61.1\u2009\u00b1\u200914.5\u2009years; current smokers 34.3%; stage III\u2010IV periodontitis 65.1%) with a total of 511 dental implants (mean function time: 13.3\u2009years [2\u201331]). Implant survival rate was 96.5%. Moderate\/severe peri\u2010implantitis was detected in 56.8% of patients and 34.7% of implants. Prevalence of buccal PISTD was 54.1% and 40.5%, respectively. Protective indicators for moderate\/severe peri\u2010implantitis included supportive peri\u2010implant care &gt; twice a year (OR\u2009=\u20090.16; 95% CI: 0.03\u20130.95), &gt;\u20092\u2009mm of keratinized tissue height (OR\u2009=\u20090.44; 95% CI: 0.21\u20130.95), and correct mesio\u2010distal implant positioning (OR\u2009=\u20090.54; 95% CI: 0.32\u20130.94).

For PISTD, protective indicators were mandibular location (OR\u2009=\u20090.45; 95% CI: 0.25\u20130.81), thick buccal soft\u2010tissue phenotype (OR\u2009=\u20090.18; 95% CI: 0.08\u20130.42), and &gt;\u20092\u2009mm of keratinized tissue height (OR\u2009=\u20090.05; 95% CI: 0.02\u20130.15).
