This growth involved both free margins and interdental papillae, and we indicated our hypothesis on the probable cause of this still-unexplained phenomenon. The growth of oral soft tissues involves several other structures, such as the linea alba and tongue indentation. Our idea holds that growth of these tissues is generated by the negative intraoral pressure created in the oral phase of swallowing and the subsequent resting position, which through the resulting suction causes a shift of these soft structures in the gaps around the dental crowns. Other hypotheses have been suggested in the past to understand this phenomenon of soft tissue growth, which still lacks data supporting etiological evidence. The purpose of this article is to thoroughly analyze and verify our model by comparing the clinical observations with citations and examples from the literature, combined with notions of physiology, biology, and physics that help in clarifying these events. To better explain the mechanisms of oral soft tissue growth, photographs of clinical cases paradigmatic of the phenomenon are shown.<\/jats:p>","DOI":"10.3390\/dj12070216","type":"journal-article","created":{"date-parts":[[2024,7,12]],"date-time":"2024-07-12T11:28:03Z","timestamp":1720783683000},"page":"216","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["An Enigmatic Soft-Tissue Creeping Phenomenon: The Spontaneous Peri-Implant Mucosa Margin and Papilla Growth, Part Two\u2014A Scientifically Supported Hypothesis Article"],"prefix":"10.3390","volume":"12","author":[{"given":"Ivo","family":"Agabiti","sequence":"first","affiliation":[{"name":"ARDEC Academy, 47923 Rimini, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4565-5222","authenticated-orcid":false,"given":"Karol Al\u00ed","family":"Apaza Alccayhuaman","sequence":"additional","affiliation":[{"name":"Department of Oral Biology, University Clinic of Dentistry, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zenzaburo","family":"Taniguchi","sequence":"additional","affiliation":[{"name":"Department of Oral Implantology, Osaka Dental University, 8-1 Kuzuhahanazonocho, Hirakata 573-1121, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuhisa","family":"Kuwano","sequence":"additional","affiliation":[{"name":"Department of Oral Implantology, Osaka Dental University, 8-1 Kuzuhahanazonocho, Hirakata 573-1121, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2804-1632","authenticated-orcid":false,"given":"Daniele","family":"Botticelli","sequence":"additional","affiliation":[{"name":"ARDEC Academy, 47923 Rimini, Italy"},{"name":"Department of Oral Implantology, Osaka Dental University, 8-1 Kuzuhahanazonocho, Hirakata 573-1121, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"474","DOI":"10.1002\/cre2.380","article-title":"An enigmatic soft tissue creeping phenomenon: The spontaneous peri-implant mucosa margin and papilla growth.
