Additionally, it sought to characterize clinical, radiological, microbiological, and immunological features of PI in smokers and non-smokers.MATERIALS AND METHODSA cross-sectional study included 40 patients (20 smokers, ≥ 10 cigarettes/day, and 20 non-smokers) requiring surgical treatment for PI. Samples of peri-implant crevicular fluid (PICF) and granulation tissue were collected during surgery for immunofluorescence and cytokine analyses. Smoking exposure was assessed through cotinine levels. Macrophage polarization (M1/M2) was determined using immunofluorescence. Clinical, radiological, and microbiological parameters were also evaluated.RESULTSSmokers showed a significantly higher proportion of M1 macrophages (70.23%) compared to non-smokers (25.09%, p < 0.005). This pro-inflammatory shift correlated positively with cotinine levels (ρ = 0.694; p < 0.005) and pack-years (ρ = 0.81; p < 0.005). No significant differences in M2 macrophage counts, cytokine concentrations, or microbiota diversity were observed between the groups. However, smokers exhibited more severe PI lesions (p = 0.04).CONCLUSIONSSmoking is associated with a pro-inflammatory shift at the cellular level due to an increase in M1 macrophage polarization in PI lesions, suggesting a pro-inflammatory response that may exacerbate tissue destruction and hinder treatment outcomes. These findings highlight the need for incorporating smoking cessation into comprehensive peri-implant care strategies to improve disease management and implant prognosis.","PeriodicalId":10455,"journal":{"name":"Clinical Oral Implants Research","volume":"45 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143992056","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}

EPG, IOS, IOSA, and IPG were used to scan the master model with respective scan bodies as test scans. Ten scanning data were gained for each technique.

Statistical models were used to evaluate implant survival, complication‐free survival rates, cumulative treatment costs, peri‐implant conditions, and patient‐reported outcomes (PROMs).ResultsThis study included 247 patients, with 283 partially edentulous posterior regions.

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.

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.

Clinical studies in English on implant therapy in patients with ADs were potentially eligible. Recorded variables included study information, patient demographics, ADs, immunosuppressants, antiresorptives, dental implant survival rate, biologic complications, and oral health-related quality of life. Descriptive statistics were performed.Results: A total of 6319 records were retrieved through database search and hand search, of which 87 studies could be included with an overweight of case reports and retrospective studies. The available evidence was characterized by a high number of studies placed low on the hierarchy of evidence. Several outcome parameters were heterogeneously reported. Glucocorticoids were the most frequently administrated immunosuppressant. The implant survival rate was overall 85.3%-100%; hereof, 46.7%-100% of implant losses occurred early, indicating a certain risk of implant failure. Despite high implant survival in oral lichen planus (OLP) patients, one study lost 42 of 55 implants in patients with untreated flare-up of OLP.Conclusions: Dental implant treatment is generally predictable with a high implant survival rate, after mid-term follow-up, in patients with ADs, of whom many receive immunosuppressants. Implant losses occurred predominantly before prosthetic loading. Particularly, patients with mucosal manifestations of their ADs seem to benefit from implant-supported restorations provided mucosal lesions are well treated.

The surgical guide files were collected in three conditions: design, post-printing, and post-plasma sterilization. The integrated precision, regional precision, and implant precision of the surgical guides were evaluated by measuring (1) T-vertex marker distance and angle, (2) surgical guide deformation after superimposition, and (3) implant 3D displacement.Results: SLA printers exhibited the lowest reproduction accuracy and implant precision during the manufacturing phase (p < 0.001) and demonstrated the lowest implant precision during the application phase. In contrast, SLM printers displayed the highest reproduction accuracy and implant precision across both phases (p < 0.001). LCD printers showed slightly lower reproduction accuracy and implant precision than SLM during both the manufacturing and application phases.Conclusion: SLM printers provide superior precision for implant surgery. Their use is recommended for printing surgical guides due to their high reproduction accuracy and implant precision during the manufacturing and application phases.
