摘要
目的:本技术报告旨在描述和详细使用微计算机断层扫描来可靠地评估填充体复合材料/牙齿界面。材料和方法:采用微计算机断层扫描技术对块状填充复合材料修复体进行扫描,以获得定性和定量有价值的信息。使用特定的算法处理二维信息,最终生成三维(3D)标本重建。3D渲染允许可视化大块填充复合材料内部的空隙,并提供定量测量。使用3D分析软件VG Studio MAX进行图像分析并评估牙齿修复界面内的间隙形成情况。特别地,为了评估内部适应性,我们使用了VG Studio Max的缺陷分析附加模块。结果:通过处理软件获得的数据突出显示了不同颜色间隙的存在和形状,代表了色度范围内的孔隙率,其中每种颜色定量地代表了一个定义良好的体积。结论:微计算机断层扫描可以获得几个定量参数,为缺陷形状和复杂性提供基本信息。然而,这种技术的局限性是不能区分没有放射不透明和低或无填充物含量的材料,例如牙科粘合剂,因此,它们很难通过软件重建可视化。
Micro-computed tomography for assessing the internal and external voids of bulk-fill composite restorations: A technical report.
Purpose: This technical report aims to describe and detail the use of micro-computed tomography for a reliable evaluation of the bulk-fill composite/tooth interface.
Materials and methods: Bulk-fill composite restorations in tooth cavities were scanned using micro-computed tomography to obtain qualitatively and quantitatively valuable information. Two-dimensional information was processed using specific algorithms, and ultimately a 3-dimensional (3D) specimen reconstruction was generated. The 3D rendering allowed the visualization of voids inside bulk-fill composite materials and provided quantitative measurements. The 3D analysis software VG Studio MAX was used to perform image analysis and assess gap formation within the tooth-restoration interface. In particular, to evaluate internal adaptation, the Defect Analysis add-on module of VG Studio Max was used.
Results: The data, obtained with the processing software, highlighted the presence and the shape of gaps in different colours, representing the volume of porosity within a chromatic scale in which each colour quantitatively represents a well-defined volume.
Conclusion: Micro-computed tomography makes it possible to obtain several quantitative parameters, providing fundamental information on defect shape and complexity. However, this technique has the limit of not discriminating materials without radiopacity and with low or no filler content, such as dental adhesives, and hence, they are difficult to visualise through software reconstruction.
