The present study aimed to validate an enhanced artificial intelligence (AI)‐driven model dedicated to automated segmentation of MIC on cone beam computed tomography (CBCT) scans and to compare its accuracy and time efficiency with simultaneous segmentation of both mandibular canal (MC) and MIC by either human experts or a previously trained AI model.Materials and MethodsAn enhanced AI model was developed based on 100 CBCT scans using expert‐optimized MIC segmentation within the Virtual Patient Creator platform. The performance of the enhanced AI model was tested against human experts and a previously trained AI model using another 40 CBCT scans. Performance metrics included intersection over union (IoU), dice similarity coefficient (DSC), recall, precision, accuracy, and root mean square error (RSME). Time efficiency was also evaluated.ResultsThe enhanced AI model had IoU of 93%, DSC of 93%, recall of 94%, precision of 93%, accuracy of 99%, and RMSE of 0.23 mm. These values were significantly higher than those of the previously trained AI model for all metrics, and for manual segmentation for IoU, DSC, recall, and accuracy (p < 0.0001). The enhanced AI model demonstrated significant time efficiency, completing segmentation in 17.6 s (125 times faster than manual segmentation) (p < 0.0001).ConclusionThe enhanced AI model proved to allow a unique and accurate automated MIC segmentation with high accuracy and time efficiency. Besides, its performance was superior to human expert segmentation and a previously trained AI model segmentation.","PeriodicalId":10455,"journal":{"name":"Clinical Oral Implants Research","volume":"70 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144236839","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}

Six months after ridge preservation, trephine cores were harvested for histologic and histomorphometric analysis.

The defects were treated according to the GBR principle using the tested material, synthetic bi-layered biphasic calcium-phosphate bone substitute (Group T), deproteinized bovine bone mineral (DBBM, positive control = PC), a mixture of the test substance and DBBM in a ratio of 1:1 (Group M) and a sham-operated empty control (negative control = NC). The defects were covered with a resorbable collagen barrier membrane. Bone formation was evaluated radiologically, microtomographically, and histomorphometrically after 11 weeks of healing.Results: All biomaterials resulted in increased volume of the augmented bone compared to the negative control. The augmented ridge volume developed to a greater extent in the tested area and in the combination of the tested bone substitute and the DBBM compared to the positive control alone (DBBM). A significant increment in a mineralized tissue and bone-biomaterial contact was observed between the test groups and the positive control.Conclusions: The synthetic BBCP appeared to result in greater bone formation volumes than the positive control (DBBM) and resulted in less contact with soft tissue.

The 3D-PITM was removed 6-9 months post-bone regeneration surgery. Cone-beam computed tomography (CBCT) data allowed for digital comparison between the actual titanium mesh and the preoperative design, analyzing the overall deviation and deformation angle of the titanium mesh. Additionally, morphology modification of the augmented areas was analyzed, and the volume was calculated.Results: The deviation of the titanium mesh immediately post-bone regeneration surgery from the preoperative design was 0.93 ± 0.22 mm. The maximum deformation angle of the titanium mesh immediately post-bone regeneration surgery was 21.49°, averaging 10.85° ± 6.70°. Correlation analysis indicated that a larger deformation angle post-bone regeneration surgery resulted in a greater deviation from the preoperative titanium mesh design. With one failure case excluded, the average actual bone augmentation achieved was 92.83% ± 26.12% of the design. Due to the small sample size, no significant correlation was found between the actual percentage of bone fill and the Root Mean Square (RMS) deviation and deformation angle of the titanium mesh.Conclusion: Although 3D-PITM-protected bone regeneration provided effective bone augmentation, a noticeable deviation remained between the titanium mesh's actual position and preoperative design.

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}

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.
