Survival and technical complications were assessed at 6 weeks after crown placement (baseline) up to 36 months. The cumulative survival of the SICs was analysed as a non-inferiority design, assuming that the difference between the titanium group and the zirconia group is not more than 10%. Technical complications were assessed based on modified USPHS criteria and Pink Aesthetic Score (PES).RESULTSIn the zirconia group, three early implant failures occurred; all of them were successfully revised. After baseline, three implants in the zirconia group were lost due to insufficient osseointegration, and therefore the SICs have to be categorised as failures even though none of the SICs failed. The non-inferiority of the zirconia group could not be confirmed, as the cumulative survival was 10.7% lower compared to the titanium group (100%). The technical complication rate was low, with no statistically significant difference between the groups. The PESs improved significantly compared to baseline, with no significant difference between the groups at 12 months.CONCLUSIONHybrid abutment SICs with PEKK base abutments on two-piece zirconia implants could be an alternative to hybrid abutments SICs with titanium base on titanium implants. However, the lower osseointegration rate of the zirconia implants has to be considered.TRIAL REGISTRATIONThis study was registered in the German Clinical Trial Register (Deutsches Register Klinischer Studien) (number: DRKS00014866).","PeriodicalId":10455,"journal":{"name":"Clinical Oral Implants Research","volume":"52 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143889312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the field of digital technology, various methods have emerged to capture EP. This review aims to critically assess current digital methodologies for capturing peri‐implant EP.Material and MethodsProspective interventional or observational clinical studies focusing on digitally mapping the emergence profile (EP) around single implant‐supported restorations were included. Systematic reviews, in vitro and animal studies, and those not emphasizing EP capture were excluded. A systematic search across four databases (MEDLINE, CENTRAL, Embase, Web of Science) was conducted on 7th August 2024 based on a previously registered protocol (PROSPERO registration number: CRD42023459484). Risk of bias was assessed with RoB 2, ROBINS‐I, and JBI critical appraisal tools. Qualitative and quantitative analyses were carried out.ResultsTwenty‐four eligible studies were identified, comprising 5 dental techniques, 12 case reports, 1 randomized controlled study, 2 cross‐sectional studies, and 4 cross‐over studies. The studies reported semi‐digital pathways, direct scanning, indirect scanning, coded‐healing abutments, and individualized use of scan bodies. Notably, the direct scanning technique showed considerable soft tissue collapse. Similar results can be achieved with indirect scanning and the conventional method.ConclusionsIndirect EP scanning appears as the most promising method for capturing peri‐implant EP. However, a confirmation of this finding requires a quantitative analysis through randomized clinical trials.","PeriodicalId":10455,"journal":{"name":"Clinical Oral Implants Research","volume":"5 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143822627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
