This study aimed to evaluate the extent of early MBL and its relationship with keratinized tissue width (KTW), bleeding on probing (BoP), and other clinical parameters to determine its prognostic significance.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n \n A prospective, longitudinal, observational study was conducted on 50 single dental implants placed in partially edentulous patients at Riyadh Elm University. Standardized intraoral periapical radiographs were obtained immediately after implant placement (T0) and 3 months later, before prosthetic loading (T1). Measurements of mesial and distal MBL were performed using Digimizer software (v6.4.0). Clinical parameters, such as KTW and BoP, were recorded, and the prognosis was classified as good, fair, poor, or hopeless. Paired\n t<\/jats:italic>\n tests and Pearson\u2019s correlation tests were applied with significance set at\n P<\/jats:italic>\n < 0.05.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n A significant difference in MBL was observed between T0 and T1 on both the mesial (\u22120.886\u2009\u00b1\u20090.944 mm,\n t<\/jats:italic>\n = \u22126.632,\n df<\/jats:italic>\n = 49,\n P<\/jats:italic>\n < 0.001) and distal (\u22120.825\u2009\u00b1\u20090.923 mm,\n t<\/jats:italic>\n = \u22126.315,\n df<\/jats:italic>\n = 49,\n P<\/jats:italic>\n < 0.001) surfaces. The mean and standard deviation values of KTW were 4.10 \u00b1 1.09 mm, ranging from 2 to 6 mm. The prognosis distribution was as follows: good (2%), fair (74%), poor (22%), and hopeless (2%). The prognosis score showed a significant correlation with KTW and BoP.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n Significant early MBL occurred within 3 months of implant placement, representing physiological bone remodeling. Early MBL, KTW, and BoP may serve as early clinical markers. Regular radiographic monitoring during the healing period is essential for ensuring long-term stability.<\/jats:p>\n <\/jats:sec>","DOI":"10.4103\/jispcd.jispcd_27_26","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T12:01:15Z","timestamp":1787832075000},"page":"378-387","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Early Marginal Bone Loss as a Determinant Factor of the Prognosis Rate of Dental Implants: A Prospective Longitudinal Observational Study"],"prefix":"10.4103","volume":"16","author":[{"given":"Abdulhadi","family":"Al-Hilali","sequence":"first","affiliation":[{"name":"Preventive Dentistry Department (Periodontics Division), College of Medicine and Dentistry, Riyadh Elm University, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed","family":"Tawfig","sequence":"additional","affiliation":[{"name":"Preventive Dentistry Department (Periodontics Division), College of Medicine and Dentistry, Riyadh Elm University, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,8,26]]},"reference":[{"key":"CIT0001-20260903","doi-asserted-by":"crossref","first-page":"865","DOI":"10.3390\/coatings11070865","article-title":"Factors influencing marginal bone loss around dental implants: A narrative review","volume":"11","author":"Kowalski","year":"2021","journal-title":"Coatings"},{"key":"CIT0002-20260903","doi-asserted-by":"crossref","first-page":"4511","DOI":"10.3390\/ma13204511","article-title":"Factors affecting implant failure and marginal bone loss of implants placed by post-graduate students: A 1-year prospective cohort study","volume":"13","author":"Ragucci","year":"2020","journal-title":"Materials (Basel)"},{"key":"CIT0003-20260903","doi-asserted-by":"crossref","first-page":"123","DOI":"10.32542\/implantology.2024013","article-title":"Evaluation of criteria for dental implant success: A systematic literature review","volume":"28","author":"Lee","year":"2024","journal-title":"J Implantol Appl Sci"},{"key":"CIT0004-20260903","doi-asserted-by":"crossref","first-page":"e70071","DOI":"10.1111\/cid.70071","article-title":"Marginal bone changes around tissue-level implants after prosthesis delivery: A multicenter prospective study","volume":"27","author":"Spinato","year":"2025","journal-title":"Clin Implant Dent Relat Res"},{"key":"CIT0005-20260903","doi-asserted-by":"crossref","first-page":"1406","DOI":"10.1111\/clr.14327","article-title":"Factors affecting radiographic marginal bone resorption at dental implants in function for at least 5 years: A multicenter retrospective study","volume":"35","author":"Trombelli","year":"2024","journal-title":"Clin Oral Implants Res"},{"key":"CIT0006-20260903","doi-asserted-by":"crossref","first-page":"630","DOI":"10.1111\/cid.13122","article-title":"Early marginal bone loss around dental implants to define success in implant dentistry: A retrospective study","volume":"24","author":"Galindo-Moreno","year":"2022","journal-title":"Clin Implant Dent Relat Res"},{"key":"CIT0007-20260903","doi-asserted-by":"crossref","first-page":"297","DOI":"10.1111\/clr.13700","article-title":"Diagnosis of peri-implantitis in the absence of baseline data: A diagnostic accuracy study","volume":"32","author":"Romandini","year":"2021","journal-title":"Clin Oral Implants Res"},{"key":"CIT0008-20260903","doi-asserted-by":"crossref","first-page":"658","DOI":"10.1902\/jop.1996.67.7.658","article-title":"Prognosis versus actual outcome.
