|Investigations of the biomechanical behaviour of hard tissues are of great significance in investigation, design and improvement of biomaterials for teeth annexes. Success of prosthetic treatment is primarily determined by biomechanical compatibility of the designs with the tissues. The reason is that the tissues are not merely a material, but a composite biological system whose reaction to denture masticatory stress is not sufficiently described in the classical theory of elasticity.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
