Mann-Whitney U test was done to compare ATS threshold and activity of sensory cortex in fMRI before and after implant installation in completely edentulous participants. Statistical result showed significant increase (P < 0.001) in activation of sensory cortex, motor cortex, prefrontal cortex, temporal lobe in participants after wearing implant retained overdenture compared with complete denture. For 200, 100, and 80 μm articulating papers non-significant change found between two test groups. The 40 and 12 μm articulating papers showed statistically significant change in ATS threshold (P < 0.05) between two test groups in 12-14 weeks. ATS threshold decreased more in participants with Implant retained overdenture prosthesis as compared with conventional complete denture prosthesis. Most of the activation was seen in prefrontal cortex and bilateral somato-sensory cortex with implant retained prosthesis compared with conventional complete denture prosthesis.","PeriodicalId":16125,"journal":{"name":"Journal of long-term effects of medical implants","volume":"35 2","pages":"83-91"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143975599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But after surgery, the Young modulus promotes stress shielding and stress simulation at the bone-implant contact, thus decreasing the density of the bone and, due to bone resorption, the dental implant fails. In this article, a material property is determined using simulation in Ansys software and using Design of Experiments (DoE) Informed Deep Learning model, which is generated for minimum stress shielding. Ashby plot is used to determine the best possible dental implant material in which five materials are obtained. Titanium and ceramics are functional in medical fields, while steels are not functional due to biocompatibility issues. However, carbon fiber-reinforced polymer (CFRP) is biocompatible and excellent for dental implants, but needs manufacturing attention. Nickel alloys can also be used for dental implants, however, their biocompatibility and technical difficulties need to be studied.","PeriodicalId":16125,"journal":{"name":"Journal of long-term effects of medical implants","volume":"35 4","pages":"1-14"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145488943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The intrusion of a natural tooth adjacent to a non-splinted dental implant is one such challenge recently observed in implant prostheses. In this comprehensive review, we delve into several potential theories that could elucidate the reasons behind tooth intrusion adjacent to a lone-standing dental implant.Materials and method: The following search terms were used for the data search: (dental implant) AND (intrusion of natural tooth). Articles written only in the English language in PubMed, Scopus, and Embase databases ranging from 1987-2023 were scrutinized and only 6 articles were included in the review.Results: Freestanding implants surrounding the intruded teeth are an uncommon occurrence that can be caused by extremely tight proximal contacts that are below the height of the contour of adjacent implants. Given the absence of a periodontal ligament in implants, their response to pressure is limited, resulting in minimal movement. However, the tooth in between them could still undergo apical intrusion. The achievement of proper proximal contact of prostheses is crucial when a natural tooth is located between implant-supported prostheses. To restore the tooth's proper contours and proximal contacts, it's suggested that the proximal contacts first be relieved. This will allow the tooth to erupt again. Clinicians need to be aware of this phenomenon and should be ready to treat it if it occurs.","PeriodicalId":16125,"journal":{"name":"Journal of long-term effects of medical implants","volume":"35 2","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144005806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the most common mechanical problems is screw loosening of the abutment. This study aims to assess the impact of abutment type (original vs. non-original) and angle of abutment (angled vs. straight) on torque reduction and screw loosening under cyclic loading conditions. Thirty titanium implants were divided into three groups (n = 10): original straight abutments, non-original straight abutments, and original 15° angled abutments. Each implant, and its respective abutments, were embedded in prepared acrylic blocks and torqued to 25 N.cm. twice, with a 10-minute interval between each torque application. Reverse torque values (RTV) were evaluated before and after 500,000 cycles of cycling loading at 75 Hz with a 100 N load, using an electrical torque meter. Data analysis was conducted using SPSS software (version 21), employing descriptive statistics, ANOVA, and independent t-tests. After cyclic loading, the mean RTV was 18.41 ± 1.86 N.cm in the group of original straight abutments, 13.18 ± 1.75 N.cm in the group of non-original straight abutments, and 14.76 ± 1.04 N.cm in original 15° angled abutments. Statistically significant differences were observed in mean RTV between the two groups of original and non-original abutments as well as between angled and straight abutments (< 0.001). Original straight abutments demonstrated lower torque loss after cyclic loading compared with both non-original and 15° angled abutments. The findings suggest that using original straight abutments may have better outcomes in preventing screw loosening and ensuring proper performance in clinical settings. However, it is essential to thoughtfully evaluate alternative abutment types and angles when necessary.","PeriodicalId":16125,"journal":{"name":"Journal of long-term effects of medical implants","volume":"35 3","pages":"53-62"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144760319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, exploring the inflammatory mediators around different surface treated dental implants is essential for long term survival of implants. The goal of this study was to compare the levels of Tumor necrosis factor-α (TNF-α) and Interleukin-10 (IL-10) in patients with sandblasted acid-etched (SLA, SLActive) and anodized (TiUnite) dental implants.Materials and methods: In this prospective clinical study, 78 patients who had undergone implant placement for missing single posterior tooth in mandible using sandblasted acid-etched and anodized surface dental implants from September 2020 to January 2021 were enrolled according to strict inclusion and exclusion criteria and were categorized into Group 1: SLA (n = 27), Group 2: SLActive (n = 26), Group 3: TiUnite (n = 25) based on the surface modification of the implants. Utilizing an ELISA kit, the levels of TNF-α and IL-10 were measured in the peri-implant crevicular fluid (PICF) at 3 months and 1-year intervals and then subjected to statistical analysis.Results: Compared to groups 1 and 2, TNF-α was high and IL-10 level was less in implants from group 3 (p < 0.05). At baseline (p < 0.05) and the 1-year follow-up (p < 0.05), there was a statistically significant difference in TNF-α and IL-10 levels between the groups on pairwise comparison. Also, an intragroup comparison revealed that in all three groups, there was a statistically significant difference from the baseline (p < 0.05).Conclusion: Higher TNF-α and lower IL-10 levels in the peri-implant crevicular fluid was observed among patients with anodized dental implants as compared to sandblasted acid-etched dental implants.","PeriodicalId":16125,"journal":{"name":"Journal of long-term effects of medical implants","volume":"35 2","pages":"69-75"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143996280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
