羟基磷灰石增强复合树脂机械性能的研究进展

摘要

With the improvement of their properties,dental resin composites have been widely used in the dental fields. As a major component of the dental resin composites, inorganic filler plays an important role in their performance. In recent years, extensive re-search has been attempted to develop materials with preferable mechanical properties. Different types of hydroxyapatite,such as parti-cles,whiskers,nanofibers and so on have been used to enhance light-cured resin composites, dramatically improving the mechanical properties of the materials. This paper mainly reviewed the advances of hydroxyapatite in enhancing the mechanical properties of the dental resin composites.%随着性能的不断改善，复合树脂在口腔医学领域中的应用越来越广泛。作为复合树脂中的重要组成部分，无机填料对复合树脂的很多性能有着重要的影响。近些年，对羟基磷灰石的研究成为一大热点，不同类型的羟基磷灰石，例如微粒、晶须和纳米纤维等，被用于制备光固化复合树脂，提高了材料的机械性能。本文就这方面的研究进展情况作一综述。
