| description | Context: Dental researchers are contradictory in their opinion
on the role of occlusion in TMD. Occlusal evaluation of both
conventional and digital methods in TMD patients will provide
the accurate information about the factors accountable for
occlusal instability. Identifying the factors responsible will
facilitate precise diagnosis and treatment for TMD.
Aim: The Aim of the study was to determine the dynamic
occlusal parameters strongly associated with the etiology of
Temporomandibular disorders.
Material and Methods: Study group consisted of 100 patients;
it included 50 patients with normal TMJ(Group I) and remaining
50 patients had a minimum of one positive sign or symptom of
Temporomandibular disorder (GroupII). The patient’s dynamic
occlusal contacts were evaluated by both conventional
and digital methods. The Articulating paper was utilized for
conventional occlusion analysis. During conventional analysis
centric, lateral and protrusive interferences were evaluated
along with loss of vertical dimension. Digital occlusal analysis
was performed with T-Scan III. Clusion time, disclusion times
were recorded for both groups.
Chi-square and Student ‘t’ statistical analyses were performed to
ascertain the association and statistically significant difference
between the groups using SPSS19.
Results: Group II patients predominantly (66%)had Groupfunction occlusion compared to Group I subject. Centric slide
more than 2 mm found to have strong influence (p-value 0.008)
on the etiology of TMD. Among the occlusal interferences
evaluated balanced side interferences had a strong correlation
with TMD with P-value of 0.003. Working side interferences,
protrusive interferences had a p-value of 0.157, 0.826
respectively, indicating weak association. T-Scan analysis
showed Group I had 0.689, 0.9136, 0.7952, 0.9794 seconds
of clusion, left, right, protrusive disclusion time respectively
compared to corresponding 1.862, 1.7995, 1.6978, 1.9296
seconds for Group II. Statistically significant difference (p≤0.05)
was found between the mean values of both groups.
Conclusion: Among the dynamic occlusal parameters
evaluated centric slide and balancing side interferences were
found to be highly influential in TMD etiology. TMD patients had
prolonged clusion and disclusion times compared to healthy
TMJ patients. |
