【摘要】：目的:探索口腔常用修复材料在CBCT影像中的灰度值的差异规律。方法:采用CBCT扫描36种口腔常用修复材料立方体,Mimics软件读取断层影像灰度值的方法。结果:探索到了36种口腔常用修复材料在CBCT影像中灰度值间的差异规律,即灰度值不仅在不同类材料间有大的差异,在同类不同品型材料间亦有较大的差别。结论:口腔常用修复材料在CBCT影像中的灰度值差异规律,提供了建立三维数字模型时选取材料和材料组合的客观依据。
[Abstract]:Objective: to explore the rule of grayscale difference of common prosthetic materials in CBCT image.Methods: the gray values of tomographic images were obtained by CBCT scanning of 36 kinds of commonly used restorative materials.Results: the differences of gray values of 36 kinds of commonly used restorative materials in CBCT images were explored, that is to say, there were great differences in gray values not only among different kinds of materials, but also among the same kinds of materials.Conclusion: the rule of grayscale difference of common prosthetic materials in CBCT image provides an objective basis for selecting materials and combination of materials in the establishment of 3D digital model.
