Subjects with temporomandibular joint disc displacement and body posture assessment via rasterstereography: a pilot

Objective:
The possible relationship between temporomandibular disorders (TMDs) and body posture is still controversial. Rasterstereography has been introduced as a radiation-free, reliable and non-invasive method to analyze three-dimensional spinal posture. The aim of this case-control study is to evaluate, through rasterstereography, body posture parameters in a group of patients with reducible unilateral dislocation of the articular disc, compared to healthy volunteers.
Patients And Methods:
Rasterstereographic recordings obtained were compared between the two groups with a paired t-student test. Furthermore, the relationship between Rasterstereographic recordings and clinical data in the TMD group were analyzed by means of multiple regression analysis.
Results:
Only lateral deviation was statistically significant different between the two groups (rms VPDM Control group 40% > TMD group, p=0.02; 43% control group VPDM max > TMD group, p<0.02). In the TMD group, a significant relationship (p<0.05) was found out between lateral and rotational deviations of the column and muscular pain, therefore suggesting a possible overactivity of the masticatory muscles, especially of lateral pterygoids' bilaterally and the left masseter.
Conclusions:
Patients with reducible unilateral disc displacement showed limited postural alterations compared to healthy volunteers, only lateral deviations (VPDM rms and VPDM-max) were statistically significant (Π<0.05) between the two groups.
