[Choice of sectional planes and advantages of the scanner in implantology].

Abstract

The future site of the implant, close anatomical obstacles and the insertion axis of single various implants, can be determined by the use of the scanner. Giving precise instructions is very important in determining the selection of sectional planes to be used the radiologist such as: axial sections, direct or reconstructed frontal sections, sagittal or reconstructed sagittal oblique sections. Precise measures can be directly realized on the scanner. When it is impossible to obtain the orthogonality of all the sectional planes, correction of the measures can be realized by using the cosinus of the angle obtained by the effective sectional plane and the ideal plane.
