After clinical examination and PICF collection at baseline, mechanical debridement was done for peri-implantitis patients, and after 3 months, clinical examination and PICF collection was done (Group IIb). The results were statistically analyzed. The PICF calprotectin level was higher in Group IIa (43.76 ± 3.64 ng/mL) as compared with Group I (11.36 ±2.53 ng/mL). Between Groups IIa and IIb, there was a significant reduction in PPD, CAL, and calprotectin from baseline to 3 months (P < 0.05). Pearson correlation in Groups IIa and IIb revealed that the correlation between calprotectin and clinical parameters was strongly positive and statistically significant. The present study suggests that there was a significant reduction in PICF calprotectin levels among peri-implantitis patients after mechanical debridement. Also, there exists a positive correlation between PICF calprotectin and peri-implant health parameters.","PeriodicalId":16125,"journal":{"name":"Journal of long-term effects of medical implants","volume":"35 4","pages":"15-20"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145489101","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 orbit and the maxillary sinus are the most prominent parts of the face and form the most common site of fracture. Reconstruction of these frequently observed fractures is necessary. The uses of polypropylene (prolene) mesh are numerous in general surgery, so its use and effects in the maxillofacial region can be explored. The aim was to evaluate the efficacy of prolene mesh in treating defects in the midface due to trauma, especially the orbital floor and anterior wall of the maxillary sinus. This was an observational study of 15 patients with midface fractures who had undergone reconstruction with prolene mesh for orbital floor and anterior maxillary sinus wall defects. Data collected included gender, age, type of fracture, clinical parameters (e.g., postoperative tenderness at the surgical site, infraorbital paresthesia, diplopia, pus discharge, and extrusion of graft), and radiological assessment for sinus and/or orbital floor continuity and bone formation. Regular follow-ups were done at 1 week and 1, 3, and 6 months. Among the 15 patients studied, all were males with a mean age of 30 years. The clinical assessment revealed positive functional outcomes. Radiographic assessment with postoperative CT scans at 6 months showed sinus wall and/or orbital floor continuity and bone formation. The study concluded that, with proper case selection, prolene mesh is a safe and reliable option in the reconstruction of the anterior maxillary sinus wall and orbital floor.","PeriodicalId":16125,"journal":{"name":"Journal of long-term effects of medical implants","volume":"35 3","pages":"23-28"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144760321","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 time-consuming aspect of the procedure is intraoperatively measuring the helical blade length. This investigation sought to determine if preoperative imaging can be reliably used to predict helical blade length and therefore reduce operative time accurately. This was a single-center, single-surgeon retrospective chart review. All subjects were operated on by the senior author at a single urban level-1 trauma center. Each patient underwent cephalomedullary nailing using a helical blade. The medical records were reviewed for demographic, imaging, and operative data. Two raters preoperatively recorded head element length, subsequently estimated helical blade implant sizes, and actual implant length used intraoperatively. In total, 134 patients were analyzed. The results demonstrated that radiographs (R2 = 0.337, p < 0.001) and computed tomography (CT) imaging (R2 ≥ 0.435, p < 0.001) could not reliably predict helical blade length, and that radiographs were more accurate than CT scans in predicting actual implant size (p < 0.001). Preoperative imaging modalities predicted the exact size only 23.8% of the time using radiographs and 17.2% of the time using CT. Preoperative helical blade implant size was estimated accurately 24% of the time. However, raters were successful in estimating the length of the helical blade within three sizes. We demonstrate that preoperative imaging modalities are unable to accurately predict helical blade length.","PeriodicalId":16125,"journal":{"name":"Journal of long-term effects of medical implants","volume":"35 3","pages":"45-52"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144760311","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}

Although the Fixion nail (Disc-O-Tech Medical Technologies Ltd., Herzliya, Israel) is an alternative technique to this method which constitutes an expandable nail, which is used to gain surgical time due to the absence of locking screws. In our department, 28 patients with tibial, femoral and humeral shaft fractures were treated by the expandable nail system for 18 months. Operative time, radiation exposure and healing time were recorded. Follow-up was obtained for a minimum of 1 year with an average of 14 months. Furthermore, in this study, we demonstrated a systematic review of the existing literature regarding the outcomes of studies on the use of the Fixion nail. In our case series, we observed one pseudarthrosis of a femoral fracture treated with a retrograde nail and two infections in tibia's fractures. In two cases, during the nail insertion, we had a failure of the implant (deformation of the tip (apex) of the nail) and two cases with delayed unions. The average operating time was 30 min (range, 26-34 min) for the tibia, 45 (range, 35-50 min) for the femur, and 20 min (range, 15-25 min) for the humerus. The radiation exposure was 0.20-0.50 s. During the systematic review, 25 studies and 790 patients with fractures of the femur, tibia and humerus were included, that met the inclusion and exclusion criteria. The mean age was 37.8 years, the time for union was 26 weeks, and 33 nonunions were observed.

The goal of our study was to develop a membrane infused with carrageenan and fucoidan silica nanoparticles for guided bone regeneration around implant sites. Carrageenan (2%) was boiled for 2 min and 5% of fucoidan were added and boiled at 60°C and further 4000 μL of PEG was added, then film casting of membrane was done. 10 ml of silica nanoparticles were mixed in 0.1 g of SiO2 nanoparticles and were added to prepared carrageenan and fucoidan solution. Then film casting was done and air dried for 24 h. Antimicrobial assay, antioxidant activity, swelling and degradation analysis, FTIR test, tensile strength testing and SEM analysis were performed. The antimicrobial effect of carrageenan membrane showed better inhibitory effect against Streptococcus mutans. Antioxidant activity of the membrane infused with carrageenan and fucoidan silica nanoparticles shows 52.93 ± 0.35 SC effect percentage. The maximum force of tensile stress at break for carrageenan fucoidan incorporated with silica nanoparticles was about 5.76 MPa and for control sample membrane was 4.34 Mpa.

Three different implant, inverted body shift (INB) (4.5*3.8*13), reverse neck collar (4.5*4.2*13) and CT implant (4.5*13). Each design was meshed into the different bone blocks creating total of six meshed models. An oblique load of 178 N from palatal side in the buccopalatal direction was applied. INB implant showed the best performance in terms of minimum stress concentration on the surrounding buccal bone specially in the reduced buccal cortical plate situation. The CT implant showed highest percentage increase in stress concentration on reducing buccal plate thickness. The new implant designs specially designed for maxillary anterior region where sufficient buccal bone is often lacking proved to be advantageous in such conditions due to the possibility of additional bone formation around the implant.
