The insufficient volume of dental ridges is one of the most severe problems regarding an oral cavity. An inadequate amount can cause problems during various types of dental treatment. Its complexity originates from the etiopathogenesis of this problem. In this study, the representatives of auto-, allo-, and xenografts are compared. The physic-chemical differences between each of them were evaluated using XRD (X-ray Powder Diffraction), a SEM (Scanning Electron Microscopy), FT-IR (Fourier transformed infrared spectroscopy), and TGA (thermogravimetric analysis). Based on the SEM images, it was observed that the origin of the material has an influence on collagen fiber compact level and porosity. Following a comparison of FT-IR spectra and XRD, the crystal and chemical structures were described. Based on TGA, different water concentrations of the investigated materials, their high thermal stability, and concentration of inorganic phase, hydroxyapatite was determined. The presented study is important because it delivers information about chemical structure and its impact on bone regeneration. This knowledge should be taken into consideration by dental clinicians, because different types of bone grafts can accommodate the achievement of various goals.
牙嵴体积不足是口腔领域最为严重的问题之一。体积不足会在各类牙科治疗过程中引发问题。其复杂性源于该问题的病因发病机制。在本研究中，对自体移植物、同种异体移植物和异种移植物的代表进行了比较。使用X射线粉末衍射（XRD）、扫描电子显微镜（SEM）、傅里叶变换红外光谱（FT-IR）和热重分析（TGA）对它们各自之间的物理化学差异进行了评估。基于扫描电子显微镜图像，观察到材料的来源对胶原纤维紧密程度和孔隙率有影响。在对傅里叶变换红外光谱和X射线粉末衍射进行比较之后，描述了晶体结构和化学结构。基于热重分析，确定了所研究材料的不同水浓度、它们的高热稳定性以及无机相羟基磷灰石的浓度。本研究具有重要意义，因为它提供了有关化学结构及其对骨再生影响的信息。牙科临床医生应考虑到这些知识，因为不同类型的骨移植能够实现不同的目标。
