摘要

假体的功能由临床程序、应用的制造技术、使用的材料及其强度参数决定。本文的目的是评估丙烯酸建筑材料的静强度和疲劳强度后直接聚合过程和老化材料。实验证实,被试材料的变形速度对其力学特性有明显的影响。随着变形速度的增加,静态压缩试验中观察到材料弹性的持续增加,并伴随着变形最后阶段工程应力的降低。Vertex的疲劳强度最高。它比抗疲劳性能最低的材料Villacryl的强度高33%。丙烯酸聚合物对频率为1hz的循环载荷的抵抗力可能成为临床过程中为患者提供全齿假牙的材料选择的指示。

Strength tests of the polymers used in dental prosthetics
The functionality of a prosthesis is determined by clinical procedures, the manufacturing technology applied, thematerial used and its strength parameters. The aim of the paper is to evaluate the static strength and fatigue strength of acrylic construction materials directly after the process of polymerisation and for aged materials. It has been confirmed that the deformation speed of the tested materials has an evident impact on their mechanical characteristics. With greater deformation speed, a consistent increase in the material elasticity was observed in static compression tests, which was accompanied by a reduction in engineering stresses at the final stage of deformation. The greatest fatigue strength was observed for Vertex. It was by about 33% greater than the strength of Villacryl – the material that has the lowest fatigue properties. The resistance of acrylic polymers to cyclic loading applied with the frequency of 1 Hz may become an indication for the selection of the material to be used in the clinical procedures in which a patient is provided with full dentures.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
