  The recent proposal of a new alignment solution for X-ray tomography, Virtual
alignment method (VAM) allowed a more accurate method to remove the possible
errors that limit the resolution and clarity of the reconstructed image. In the
field of dentistry, the movement of patients during the scanning poses as one
of the major factors hindering the final reconstructed image quality. Here, the
patient's movement was artificially given to the projection image set and the
newly proposed algorithm using the sinogram and the fixed point was applied to
the tooth sample to compare the reconstruction image to the actual projection
image set. The new alignment method showed promising results by reducing the
margin of errors down to a few micrometer, which will allow the production of
high-quality dental prostheses with accuracy and precision. We hope that the
newly proposed alignment method can be further investigated to be applied more
readily in the filed of dentistry ot provide better quality images of patients
to make a more accurate diagnosis and prostheses.
