Background: Immediate functional loading of one-piece dental implants has become an accepted treatment modality for fixed restorations in fully edentulous mandibles and maxillae. Nevertheless, studies regarding immediate loading procedures in extraction sites in both the jaws, as well as in segment reconstructions and single-tooth replacements, are limited. Purpose: The purpose of this study was to evaluate the presently used protocol for immediate functional loading (within maximum 3 days) of one-piece implants which are placed according to the following methods as published by the IF. Materials and Methods: This prospective cohort study included totally 87 consecutively treated patients who receive 1169 immediately loaded one-piece Strategic Implant ® , supporting fixed complete-arch maxillary or mandibular metal-ceramic bridges or segment reconstructions in both the jaws. All implants were placed by one treatment provider, who delivered also the prosthetics and controlled all cases himself over the years. Data were extracted by an experienced dentist from the patient records and from panoramic X-rays. A number of patients were interviewed at the end of the observation period. Although a total of 5100 implants were placed and observed for 12 – 57 months totally (with 105 implants out of these, having failed), this article reports the detailed results only for 1169 implants which have been followed for at least 48 months. Results: Immediate functional loading of using multiple, cortically anchored basal screw implants as a support for fixed full-arch and segment prosthesis in the upper and lower jaw demonstrated a high cumulative implant survival rate after an observation period of up to 57 months. Neither hypertension nor diabetes and neither smoking nor bending of the implant's neck had an influence on the success of the implants observed in this study. Within the limits of this study (5100 Strategic Implants were observed over a period of up to 57 months), “peri-implantitis” was not observed at all. Conclusion: The treatment concept developed for the technology of the Strategic Implant® is safe and effective and it avoids bone augmentations and “peri-implantitis”.

Introduction: The number of newly diagnosed skin cancers per year is greater than the sum of the four most common cancers: breast, prostate, lung, and colon. The implementation of primary and secondary prevention measures, over the last 2 to 3 decades, has made a major contribution to successful treatment. Aim: Evaluate the accuracy and reliability of teledermoscopic versus clinical diagnosis for skin cancers when diagnostic algorithms are used, and when GPs and surgical specialties are involved in the clinical procedure. Methods: Digital dermoscope (TS-DD, by Teleskin company) was used for the acquisition of teledermoscopic photographs and specialized teledermoscopic software was used for clinical examination and teledermoscopic consultation. The teledermoscopic procedure itself was performed in two steps. The first step was a clinical examination using the ABCDE rule with digital dermoscopic photography of the suspected lesion. The second step was a 2-step dermoscopic evaluation using the second step ABCD algorithm for the second step. Accuracy and diagnostic reliability were calculated for: teledermoscopic diagnosis versus histopathological diagnosis; clinical diagnosis versus histopathological diagnosis and teledermoscopic diagnosis versus clinical diagnosis. Results: The study included 120 patients with 121 Pigmented Skin Lesions, of which 75 (62%) were benign and 46 (38%) were malignant lesions (6 melanomas and 40 NonMelanoma Skin Cancers). Diagnostic accuracy between teledermoscopic and histopathologic diagnosis was 90.91% and reliability k=0.81; between clinical and histopathological diagnosis the diagnostic accuracy was 82.64% and the reliability k=0.64 and between the clinical and teledermoscopic diagnosis the diagnostic accuracy was 81.82% and the reliability k=0.62. Conclusion: The achieved diagnostic accuracy between clinical and teledermoscopic diagnosis, when using diagnostic algorithms, establishes a feasible screening path for skin cancers and indicates that general practitioners and specialized surgeons may equally be involved in prevention.

Background:Bicortical screw implants may be used in both healed bone and fresh extraction sockets and loaded immediately. To date, there have not been too many studies reporting clinical results of such screws used in periodontally involved sites. This study aimed to assess many aspects of bicortical screw implants used to retain full-arch and segmental cemented prostheses in the rehabilitation of the mandible and maxilla in patients with or without a history of periodontal disease.Materials and Methods:This retrospective review involved 87 patients, of whom 77 had a history of periodontitis diagnosed before implant placement and 10 did not. They were treated following the same surgical procedure and received a total of 1019 implants which were immediately loaded with fixed prosthetic works.Results:A total of 1019 polished surface, one-piece, bicortical screw implants were used in 87 patients who underwent the same surgical treatment, i.e., tooth extraction and immediate implant placement were investigated, of which 526 were placed in the healed bone and 493 in fresh extraction sockets with the mean follow-up time of 22.2 ± 7.3 months. Results were analyzed using log-rank test, the Kaplan–Meier method, Chi-square test, and t-test. Cumulative survival at 12, 24, and 35 months after placement was 99.3%, 98.6%, and 97.0%, respectively.Conclusion:Bicortical smooth surface implant concept with immediate loading protocol provided predictable outcomes and survival rate of 99% in patients with and without a history of periodontitis. More studies are needed to further support the clinical advantages of bicortical anchoraged smooth surface implants.

Introduction: Rehabilitation with dental implants of total or partial edentulousness in the maxilla encounters a number of difficulties due to the anatomical distinctions and the topography of this region. The maxilla is rigidly attached to the other skull bones, and therefore, its structure is functionally adapted to transmit loads through three main buttresses. Outside these supporting zones, the bone structure is poorly mineralized, or its volume is limited to the thin bone layer. In strategic implantology, a number of defined clinically-proven surgical methods have been proposed to utilize these maxillary load transmitting buttresses. This study was aimed to evaluate its safety with respect to maxillary sinus complications as a result of anchoring Strategic Implants ® in the cortical boundaries of the sinus and/or passing through it, to reach the pterygoid plate of the sphenoidal bone. Materials and Methods: This prospective cohort study was carried on 217 cortico-basal implants penetrating through the cortical walls of the maxillary sinus (Simpladent GmbH, Gommiswald, Switzerland), placed between September 2013 and December 2014 in a total of 70 patients (131 maxillary sinuses). Two hundred and four implants were anchored in the cortical bone of the sinus protruding into the sinus up to 3 mm, and 13 were placed trans-sinuously. Results: None of the implants failed during the observation period, with only one instance of adverse reaction in the maxillary sinus to the polished corticobasal implants. Discussion: Anchoring polished corticobasal implants in the wall of the maxillary sinus as well as in the pterygoid plate of the sphenoid bone is a safe and effective procedure that per se (if executed properly) does not cause any adverse reaction of the maxillary sinus.

Introduction/Objective Frostbite is a cold-induced injury of the tissue caused by the freezing of intraand extracellular water, and characterized by thrombosis and ischemic necrosis. Although individual, socioeconomic, and environmental factors are all considered fundamental determinants of human health in general, their role in the occurrence of frostbite remains largely unknown. The aim of this study was to examine the associations among these factors and frostbite for patients in Belgrade, Serbia. Methods We investigated a total of 24 patients that were hospitalized and treated for frostbites at the Clinic for Burns, Plastic, and Reconstructive surgery, Clinical Center of Serbia, 2008-2017. Results The majority (88%) of the patients were male, 58% were long-term alcohol consumers, 46% were long-term smokers, and one patient was drug addict. Of the patients, 14 (58%) had no income and depended on government support, 10 (42%) were employed in physical labor or work on the field, and three (13%) of the patients were homeless. Of the 24 frostbite patients identified, deep frostbite accounted for 18 (75%), of whom 17 (70.8%) had an operative outcome. A majority of patients (42%) sustained frostbite when the temperature was in the range of-5-0°C on the date of occurrence. Conclusion The results of our study showed that individual, social, and environmental factors were important determinants of frostbite. Our results will contribute to existing evidence for risk factors related to frostbite and will allow for comparisons across countries where these factors have been examined.
