guide to the report data reading
The elaborated data are divided into PRE and POST sections, for the
comparison of two tests of the same acquisition session, or of tests made
in different temporal session. This is helpful in evaluating the treatment
efficacy and for the patient follow up.
The graphic shows a dental arch, which works as a 2D morphological map,
on which are superimposed icons “target” style (they will be so called in
the rest of the document), positioned in order to summarize the occlusal
condition, according to the calculated indices, whose values are given in
the table below.
• POC: percentage overlapping coefficient
It is an index of the standardized contraction symmetry within the
same muscular couple. It expresses, in percentage terms, the difference
in electrical signal generated by a muscle couple during a maximum
voluntary contraction (MVC) compared to its homologous standardized
value.
If the two homologous muscles of each pair are contracted in perfect
symmetry, thanks to a functionally balanced dental occlusion, the POC
result is expected close to 100%.
While if muscle couples show standardized values in percentage terms
different from each other, the POC turns out to be considerably less than
100%.
When the POC exceeds 83%, there is a normal muscular symmetry,
induced by the contact of the teeth, otherwise, the dental contact is
influencing the neuromuscular equilibrium of the patient.
With the 4-channel protocol, are calculated the POC of the anterior
temporal and masseter muscles, which are respectively indicated by POC
TA and POC MM, indicators of the influence of tooth contact on the
