6.7.1.2 Anatomical parameters<br />

The point of interest, i.e. the point where to perform the tomography, is<br />

based on the statistical model of the dental arch. It is selected using the<br />

standard European mode to number teeth, using two digits. The first<br />

digit defines the quadrant (from 1 to 4) while the second digit identifies<br />

the tooth itself, from 1 to 8. It means that selection of the point of<br />

interest must be done by entering into the unit a two-digit number as<br />

above described.<br />

In case of use of the American standard, which is based on a different<br />

method, see next Figure 21 where both European and American standard<br />

numberings are provided, to find out the number (based on European<br />

standard) to input into the unit.<br />

The linear tomography implemented on STRATO X is based on a<br />

statistical model of dental arch, as defined in international literature.<br />

However, it must be considered that the natural deviation from the model<br />

due to the individual variability can lead to the possibility that the point<br />

of interest may be not perfectly centred on the middle of the tomographic<br />

images.<br />

To overpass that, STRATO X uses the possibility to introduce correcting<br />

factors that allows a better centring of the patient; these factors are<br />

called longitudinal offset and transversal offset.<br />
