This study investigated whether FD and lacunarity, measured on panoramic radiographs and cone-beam computed tomography (CBCT), can predict early implant loss in the mandible. Methods A retrospective case-control study included 48 patients—24 with early implant failure and 24 with implants surviving at least 5 years without periimplantitis. All had panoramic radiographs, and a subset of 30 patients (15 per group) also had CBCT scans. FD and lacunarity were assessed in 3 mandibular regions: frontal, premolar, and molar. ImageJ software with box-counting method was used. FD from panoramic images was calculated using the White and Rudolph method; CBCT-based FD values were derived using both the White and Rudolph and the Kato et al. methods. Results No significant differences in FD or lacunarity values were found between groups in any region on either imaging modality (P > .05). Conclusions Fractal dimension and lacunarity values obtained from panoramic radiographs and CBCT images did not demonstrate predictive capability for early implant failure. Although fractal analysis offers a non-invasive approach to assess trabecular bone architecture, it should not be used in isolation to estimate implant prognosis. Clinical Relevance While fractal analysis may provide complementary insights into bone microstructure, its standalone application lacks sufficient reliability for predicting early dental implant failure. Future studies involving larger cohorts are warranted. true true 2025 true true true false true false NONE 2026-08-19 false 5 0 5 5 0 5 5 4 5 5 5 5 5 5 0 0 5 5 5 5 0 1 1 Folyóiratcikk Journal Article 24 5 Könyvrészlet Chapter in Book 25 0 Könyv Book 23 0 Egyéb konferenciaközlemény Conference paper 31 0 Egyéb konferenciakötet Conference proceedings 32 0 Oltalmi formák Protection forms 26 0 Disszertáció Thesis 28 0 Egyéb Miscellaneous 29 0 Alkotás Achievement 22 0 Kutatási adat Research data 33 0 Folyóiratcikk Journal Article 24 0 0 0 Könyvrészlet Chapter in Book 25 0 0 0 Könyv Book 23 0 0 0 Egyéb konferenciaközlemény Conference paper 31 0 0 0 Egyéb konferenciakötet Conference proceedings 32 0 0 0 Oltalmi formák Protection forms 26 0 0 0 Disszertáció Thesis 28 0 0 0 Egyéb Miscellaneous 29 0 0 0 Alkotás Achievement 22 0 0 0 Kutatási adat Research data 33 0 0 0 2026 0 5 5 5 5 D1 false false false false 2025-09-07T09:00:30.082+0000 Fogászati és Szájsebészeti Oktató Intézet (SE / FOK) 3 15 1 4 0 true Language 10002 /api/language/10002 Angol English true 2 true PersonAuthorship 127675588 /api/authorship/127675588 1 0.25 true false true Author 10064485 /api/author/10064485 Iványi Dóra true 10064485 true Iványi Dóra true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 127675589 /api/authorship/127675589 2 0.25 false false false Author 10029071 /api/author/10029071 Kivovics Márton true 10029071 true Kivovics Márton true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 127675590 /api/authorship/127675590 3 0.25 false false false Balázs Richárd true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 127675591 /api/authorship/127675591 4 0.25 false true false Author 10018900 /api/author/10018900 Németh Orsolya true 10018900 true Németh Orsolya true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PublicationIdentifier 29771407 /api/publicationidentifier/29771407 PlainSource 6 /api/publicationsource/6 PublicationSourceType 10001 /api/publicationsourcetype/10001 true true true DOI DOI https://doi.org/@@@ true true 6 true NONE IDENTICAL 10.1016/j.identj.2025.103880 https://doi.org/10.1016/j.identj.2025.103880 false true PublicationIdentifier 29913363 /api/publicationidentifier/29913363 PlainSource 1 /api/publicationsource/1 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true IDENTICAL 001566494400001 https://www.webofscience.com/wos/woscc/full-record/001566494400001 true true PublicationIdentifier 29809930 /api/publicationidentifier/29809930 PlainSource 3 /api/publicationsource/3 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true IDENTICAL 105014498040 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-105014498040 true true PublicationIdentifier 29913364 /api/publicationidentifier/29913364 PlainSource 17 /api/publicationsource/17 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true PubMed PubMed http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=@@@&dopt=Abstract true true 17 true IDENTICAL 40886504 http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=40886504&dopt=Abstract true true Classification 12276 /api/classification/12276 true true Keyword 1005369 /api/keyword/1005369 true 1005369 true Keyword 1008950 /api/keyword/1008950 true 1008950 true Keyword 1011015 /api/keyword/1011015 true 1011015 true Keyword 1021350 /api/keyword/1021350 true 1021350 true Keyword 1626072 /api/keyword/1626072 true true Keyword 2853904 /api/keyword/2853904 true true SjrRating 11572339 /api/sjrrating/11572339 15 0.1 journal RatingType 10002 /api/ratingtype/10002 sjr true true ClassificationExternal 3501 /api/classificationexternal/3501 true 3501 true D1 DIRECT true true /api/publication/36309635 <div class="JournalArticle Publication long-list"> <div class="authors"> <img title="Forrásközlemény" style="float: left" src="/frontend/resources/grid/publication-core-icon.png"> <img title="Idézőközlemény" style="float: left" src="/frontend/resources/grid/publication-citation-icon.png"> <div class="autype autype0"> <span class="author-name" mtid="10064485"><a href="/gui2/?type=authors&mode=browse&sel=10064485" target="_blank">Iványi Dóra ✉ (<span class="authorship-author-name">Iványi Dóra</span> <span class="authorAux-mtmt"> Szájsebészet</span>) </a> </span> <span class="author-affil"><span title="Semmelweis Egyetem">SE</span>/<span title="Fogorvostudományi Kar">FOK</span>/Fogászati és Szájsebészeti Oktató Intézet</span> ;&nbsp;&nbsp;&nbsp;
