Gingival thickness was measured preoperatively, while midfacial recession, papilla recession, and horizontal contour collapse were evaluated at 3 and 6\u202fmonths postoperatively. Comparative analyses of soft tissue alterations between the groups were conducted, alongside an examination of the correlation between gingival thickness and soft tissue changes.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n A total of twenty-two patients, encompassing 30 sites, completed the 6-month follow-up period. At 6\u202fmonths, the thin phenotype group exhibited a midfacial recession of 0.73\u202f\u00b1\u202f0.69\u202fmm, compared to 0.89\u202f\u00b1\u202f0.52\u202fmm in the thick phenotype group. No statistically significant differences in soft tissue alterations were observed between the groups, and no statistically significant association correlation was identified between gingival thickness and soft tissue changes.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Within the constraints of this study, no statistically significant differences in soft tissue alterations were observed between different gingival phenotype groups at 6\u202fmonths following IIPP. Since the study was powered to detect a clinically relevant difference of 1\u202fmm, it lacked the sensitivity to definitively confirm or rule out the more subtle difference observed.<\/jats:p>\n <\/jats:sec>","DOI":"10.3389\/fmed.2026.1888629","type":"journal-article","created":{"date-parts":[[2026,8,19]],"date-time":"2026-08-19T04:40:24Z","timestamp":1787114424000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Influence of gingival thickness on soft tissue changes after immediate implants and immediate provisionalization in the esthetic zone: an ambispective cohort study"],"prefix":"10.3389","volume":"13","author":[{"given":"Wang","family":"Maoxia","sequence":"first","affiliation":[{"name":"West China School of Public Health and West China Fourth Hospital, Sichuan University","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mo","family":"Anchun","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Oral Diseases, National Center for Stomatology, National Clinical Research Center for Oral Disease, Department of Oral Implantology, West China Hospital of Stomatology, Sichuan University","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wu","family":"Yan","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Oral Diseases, National Center for Stomatology, National Clinical Research Center for Oral Diseases, Department of West Outpatient, West China Hospital of Stomatology, Sichuan University","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,8,19]]},"reference":[{"key":"ref1","first-page":"quiz 16","article-title":"Single-tooth replacement in the aesthetic zone with immediate provisionalization: fourteen consecutive case reports","volume":"10","author":"W\u00f6hrle","year":"1998","journal-title":"Pract Periodontics Aesthet Dent"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"132","DOI":"10.1111\/prd.12044","article-title":"Immediate implants at fresh extraction sockets: from myth to reality","volume":"66","author":"Vignoletti","year":"2000","journal-title":"Periodontol"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"1188","DOI":"10.1111\/cid.12212","article-title":"Does timing of implant placement affect implant therapy outcome in the aesthetic zone?
