Bone Quality When viewing a two-dimensional radiograph, information on bone width is evidently scarce. The superimposition of structures renders interpretation of a radiograph even more complex. Conventional intra-oral radiography does not reveal significant changes of the cancellous bone.作者: 6Applepolish 時間: 2025-3-28 22:09
