Does the Use of Surface Electromyography Could Improve Quality of Life among Patients Rehabilitated by Mandibular Overdentures on Different Attachments?

Objective: To analyze and compare changes of quality of life parameter among dental patients rehabilitated by the implant-supported overdentures with different attachment systems. Material and Methods: Forty-eight patients were recruited as a study cohort. The implant placement procedure was based on the results obtained by CBCT scanning and individualized surgical templates manufactured for correct implant placement. Each individual received two k3Pro Implants (Sure Type with 4.0 or 4.5 mm in diameter) at the intraforaminal area due to standard protocol of implantation provided by the manufacturer under local anesthesia. All patients were distributed between two groups based on the fact of using either Locator- or ball-attachments. Rank correlation was measured using Spearman correlation coefficient, while linear correlation was evaluated by Pearson correlation coefficient. Results: No statistically meaningful differences were noted regarding patients’ distribution among groups considering age (p>0.05) and gender (p>0.05). Provided patient-level analysis demonstrated that increase of conventional full denture service time was positively correlated with escalation of OHIP-EDENT scores. The most prominent inter-correspondences were noted specifically between longevity of denture service and elevation of scores within “Functional limitation” (r=0.61; p<0.05), “Physical pain” (r=0.51; p<0.05) and “Physical disability” (r=0.57; p<0.05) subdomains. No statistically argumented regressions were noted between increase tendency of OHIP-EDENT scores and gender (p>0.05) or age (p>0.05) parameters. Conclusion: Significant improvements of quality of life measured with OHIP-EDENT were noted for both types of attachments compared to the pre-treatment situation independently of additionally provided surface electromyography-based alignment

Transfer factor as technologies socio-economic development of Western Ukraine

We consider some aspects of technology transfer between Ukraine and Poland, which is a factor in enhancing regional development. Deemed appropriate to the formation of the Polish-Ukrainian space technology cluster, as an effective mechanism for technology transfer interstate

European integration of Ukrainian research institutions: prospects of using of EU funds

The goal of this article is to present perspective of using European funds in Ukrainian research institutions. Effective cooperation of Ukraine with the European Union in the direction of research will foster the intensification of political and economic relations, the use of new mechanisms to stimulate research and development of public awareness of the importance of science for the development of society. Coordination of joint research interest is added by the integration of Ukraine (by creating a single space science and technology) with the European Union. Of particular importance is the fact that the mutual benefits of the research programs

Non-Standard Errors

In statistics, samples are drawn from a population in a data-generating process (DGP). Standard errors measure the uncertainty in estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence-generating process (EGP). We claim that EGP variation across researchers adds uncertainty: Non-standard errors (NSEs). We study NSEs by letting 164 teams test the same hypotheses on the same data. NSEs turn out to be sizable, but smaller for better reproducible or higher rated research. Adding peer-review stages reduces NSEs. We further find that this type of uncertainty is underestimated by participants
