QUANTIFICATION OF DENTAL MOVEMENTS IN ORTHODONTIC FOLLOW-UP:
A NOVEL APPROACH BASED ON REGISTRATION OF 3D MODELS OF DENTAL CASTS
On the other side, RMS value provides a reliable
indication concerning the differences between
the two casts, which seems to be adherent to
the importance of modifications suffered by
the patients. In addition, patients who were not
treated from an orthodontic point of view, show
lower RMS parameters, and this suggests that the
metrical parameter is strictly linked to the general
modification of the 3D position of dental crowns.
Some
limits
should
be
acknowledged:
first,
modifications
highlighted
by
the
registration
procedures
consider
also
dental
eruption,
and
therefore
are
partly explained by orthodontic therapy.
A possible improvement may consider the
elaboration of each dental element, in order to
separately consider already erupted elements.
Another important limit concerns the possible
correlation of RMS with clinical parameters linked
to the gain in dental function and aesthetics due to
orthodontic therapy. This point is crucial, as it may
verify if RMS value in registration of 3D models
of dental cases do represent a potentially useful
clinical parameter for assessing the success of
therapy.
5. Conclusions
In conclusion, a novel protocol for the assessment
of dental displacement in orthodontic therapy is
proposed: further studies on a large sample of
patients may provide additional information about
the clinical advantages which may derive from its
application.
