Aims: To compare the short-term efficacy of treatment with a stabilization
appliance compared with that of a non-occlusal, control
appliance in patients with temporomandibular disorders (TMD)
mainly myogenous origin. Methods: A randomized, controlled
trial was performed with 60 patients suffering from myofascial
pain. Patients were randomly assigned to a treatment or a control
group. The treatment group was treated by means of a stabilization
appliance and the control group by means of a non-occlusal
appliance. Symptoms and signs were registered before and after 10
weeks of treatment. Results: Improvement of overall subjective
symptoms was reported in both groups, but significantly more
often in the treatment group than in the control group (P = .000).
The prevalence of daily or constant pain showed a significant
reduction in the treatment group (P = .028) compared with the
control group. There was a significant decrease in the number
tender masticatory muscles in the treatment group (P = .018) compared
with the control group. Conclusion: The results of this
short-term evaluation suggest that the stabilization appliance
more effective in alleviating symptoms and signs in patients with
TMD of mainly myogenous origin than a control, non-occlusal
appliance. The stabilization appliance can therefore be recommended
for the therapy of these patients.
