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。Objective： To explore the differences of CBCT image gray value of commonly used dental materials. Methods： CBCT was used to scan 36 kinds of commonly dental material blocks, the tomographic image gray value was measured by Mimics software. Re- suits ： CBCT image gray values of the materials were obtained. There were differences of the gray values of the materials not only among the different types, but also among the different varieties of the same materials. Conclusion： The discipline of CBCT image gray value differences of commonly used dental materials provided an objective basis for the establishment of 3D digital model including dental ma-terials.
