In this work we present the features and the properties of natural and synthetic apatites, which we use in an experimental study of various commercial products composed by calcium phosphate. After having considered the general concepts of biomaterials and biocompatibility, we describe non biological tests used for the characterization of these products. Biomaterials used in this study are: reabsorbable Dac Blu, non reabsorbable Dac Blu, non reabsorbable atomized Dac Blu, non reabsorbable thin Dac Blu, reabsorbable Biocoral 450, Calcitite 2040-12, Orthogel, Apagen, BTF 65, Calcitite 4060-2 Osprogel, Bio-oss, Biostite, Osprovit, Merck Hydroxiapatite. Tests used are: X-ray fluorescence (XRF), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric and thermodifferential analysis (TG, DTG, DTA), scanner-ing electron microscopy (SEM) morphological analysis. Last but not least, we underline the particular features of these tests whose interpretation allows a more precise definition of the bioactivity of a biocompatible material.
在这项工作中，我们展示了天然和合成磷灰石的特性，这些磷灰石被我们用于对各种由磷酸钙组成的商业产品进行实验研究。在考虑了生物材料和生物相容性的一般概念之后，我们描述了用于表征这些产品的非生物学测试。本研究中使用的生物材料有：可吸收的Dac Blu、不可吸收的Dac Blu、不可吸收的雾化Dac Blu、不可吸收的薄型Dac Blu、可吸收的Biocoral 450、Calcitite 2040 - 12、Orthogel、Apagen、BTF 65、Calcitite 4060 - 2 Osprogel、Bio - oss、Biostite、Osprovit、默克羟基磷灰石。使用的测试方法有：X射线荧光光谱法（XRF）、X射线衍射法（XRD）、傅里叶变换红外光谱法（FT - IR）、热重和热差分析（TG、DTG、DTA）、扫描电子显微镜（SEM）形态分析。最后但同样重要的是，我们强调了这些测试的特殊特征，对其进行解释有助于更精确地定义生物相容性材料的生物活性。
