Two FDPs were re-bonded, four abutment teeth required endodontic treatment, and two presented periodontal issues. Additionally, 2 FDPs exhibited a loss of surface luster, 4 exhibited color mismatches, and 4 exhibited surface staining (all scored 4). Kaplan-Meier analysis revealed a 40.7 % survival rate for mechanical failures and a 36.2 % survival rate when biological complications were included.</div></div><div><h3>Conclusions</h3><div>The results of a three-year follow-up study indicated that 3D-printed resin composite FDPs present failures mainly in the connector region, suggesting the need for further design improvements.</div></div><div><h3>Clinical Significance</h3><div>Three-dimensionally printed resin composite FDPs offer certain advantages but current restorations could be considered as long-term provisional due to the incidence of mainly mechanical failures up to 3 years.</div></div><div><h3>Clinical Trial Registration</h3><div>Clinical Trials.Gov, NCT04600297.</div></div>","PeriodicalId":15585,"journal":{"name":"Journal of dentistry","volume":"160 ","pages":"Article 105887"},"PeriodicalIF":4.8,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144258183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
