Modifica di Occlusion and Posture (sezione)

====Contents to refute the correlation====
As far as the authors contesting the correlation between occlusion and posture are concerned, we can report the results of Giuseppe Perinetti et al.<ref name=":8" /> of 122 subjects, including 86 males and 36 females (age range 10.8 to 16.3 years) who tested negative for temporomandibular disorders or other conditions affecting the stomatognathic systems, with the exception of malocclusion. An assessment of dental occlusion included dentition stage, molar class, overjet, overbite, anterior and posterior crossbite, scissor bite, mandibular crowding, and dental midline deviation. Furthermore, body posture was recorded through static posturography using a vertical force platform. Recordings were performed under two conditions: 

#mandibular rest position (RP)
#dental intercuspid position (ICP).

The conclusion was that all posturographic parameters showed great variability and were very similar between recording conditions. Furthermore, a limited number of weakly significant correlations, mainly for the overbite phase, were observed when using multivariate models.

The author's current findings were that regarding the use of posturography as a diagnostic aid for subjects affected by dental malocclusion, they do not support the existence of clinically relevant correlations between malocclusion typology and body posture.

Another interesting article in the group contesting the correlation comes from Benjamin Scharnweber et al.<ref name=":9" /> examined 87 male subjects with a mean age of 25.23 ± 3.5 years (18 to 35 years). The dental models of the subjects were analyzed. Postural control and plantar pressure distribution were recorded from a weight bearing platform. Possible orthodontic and orthopedic influencing factors were determined from a medical history or questionnaire. All tests performed were randomized and repeated three times each for intercuspid position (ICP) and locked occlusion (BO). 

In this study, the ICP occlusal position was found to increase body sway in the frontal (p ≤ 0.01) and sagittal (p ≤ 0.03) planes compared to the BO position, whereas all other 29 correlations were independent of position of the occlusion.

For both ICP or BO cases, angle therapy, midline shift, crossbite, or orthodontic therapy was found to have no influence on postural control or plantar pressure distribution (p > 0.05).

In conclusion, the author confirms that persistent dental parameters have no effect on postural sway. Furthermore, postural control and plantar pressure distribution were found to be independent postural criteria.
