Abstract
X-ray microtomography is a miniaturized form of traditional axial computerized tomography that allows three dimensional investigations on small radiopaque objects, with an high resolution (about 5–μm), in a non-invasive and non-destructive way.
Compared with the conventional electronical and microscopical techniques that produce only bidimensional images, microCT is used to obtain a three dimensional analysis of a sample with no need to cut and no need of particular chemical treatments at all.
Therefore, X-ray 3D microtomography may satisfy the ideal requirements of 3D microscopy:
-
Investigation of a sample without preparation or alterations;
-
Production of non-invasive, non-destructive 3D images with a sufficient magnification;
-
Effectiveness of measurements of internal structure’s numerical features (morphology, structure and ultra-structure)
This justifies the application of this innovative technique not only in medicine and odontostomatology, but also in biomedical engineering, material science, biology, electronic, geology, archeology, petroleum and semiconductors industries.
In this section of the book will be showed different possibilities of microtomographic applications in biomedical field:
-
Biomaterials and Bone first, will show microtomographic appliance in structural characterization during the several phases of scaffolds’ designing and manufacturing, also after their application in implantology’s bone regeneration and maxilla-facial surgery;
-
Fixture-Abutment connection characterization, in the second place, will show the results of the 3D micro-characterization analysis of fixture-abutment interface to observe no correct compliances.
