Clinical and ultrasonographic measurements, including PSTD class and subclass, probing depth, keratinized mucosa width (KMW), mucosal thickness (MT) at 1\u00a0mm and 3\u00a0mm, buccal bone distance (BBD) and buccal bone thickness, were evaluated in healthy implants and implants with PSTD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 153 subjects with a total of 176 dental implants were included. The prevalence of PSTD was 54.2% and 56.8% on a patient and implant level, respectively. The most frequent type of PSTD was the one characterized by having both an implant\u2010supported crown longer than the clinical crown of the homologous tooth and a visible abutment\/implant fixture exposed to the oral cavity. The multivariate analysis showed that the presence of an adjacent implant, a longer time of the implant in function, limited MT, reduced KMW, and increased BBD were significantly associated with the presence of PSTD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>PSTDs are common findings in the esthetic region. Several risk indicators for this condition, such as presence of an adjacent implant, increased time in function of the implant, higher BBD, lower KMW, and MT were identified.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jper.21-0402","type":"journal-article","created":{"date-parts":[[2021,11,17]],"date-time":"2021-11-17T11:39:09Z","timestamp":1637149149000},"page":"857-866","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":59,"title":["Prevalence
