The logistic regression analyses revealed that, after correcting for the background variables, stabilisation appliance treatment was a strong explanatory factor for a positive treatment outcome, with a significance of P = 0.0013 compared to patients belonging to the control group. Background variables of significant importance for the treatment outcome were male sex (positive) (P = 0.0268), and severe or very severe TMJ pain (negative) (P = 0.0034). These findings indicate that not only the treatment with a stabilisation appliance but also sex and the intensity of the TMJ pain before treatment might influence the treatment outcome in patients with TMD of arthrogeneous origin.
Fifty-eight patients with temporomandibular disorders of arthrogenous origin were assigned to two equally sized groups: a treatment group given a stabilization appliance; and a control group, given a control appliance. The study covered 10 weeks. The treatment outcome regarding changes in severity of temporomandibular joint pain on a verbal scale was compared to changes in the condyle-fossa relationship in horizontally corrected oblique lateral transcranial radiographs taken with and without the appliance. Condyle-fossa relationship and structural bone changes were observed before treatment in corrected lateral tomograms. The purposes of this study were to compare changes in the condyle-fossa relationship in patients with temporomandibular disorders of arthrogenous origin treated with either a stabilization or a control appliance in a double-blind controlled study, and to compare the changes in the condyle-fossa relationship with the short-term treatment effect in the two treatment groups. The radiographic appearance of the temporomandibular joint was also studied.
To compare the long-term effect of treatment with a stabilization appliance (group T) and treatment with a control appliance (group C) in temporomandibular disorder (TMD) patients with myofascial pain. In this controlled trial, 60 patients (mean age 29 years) with myofascial pain were evaluated after 10 weeks of treatment with either a stabilization appliance or a control appliance. All 60 patients were then assigned to 1 of 3 groups according to demand for treatment. Seventeen patients from group C requested another appliance and were given a stabilization appliance, thus creating a mixed group (group M). A significant difference in improvement of overall subjective symptoms in an intent-to-treat analysis between groups T and C was found at the follow-ups. In a survival analysis of treatment compliance, a significant difference was found between groups T and C. At the 6- and 12-month follow-ups, a significant reduction in myofascial pain, as measured on a visual analog scale, was found in all three groups. A significant decrease in frequency and intensity of myofascial pain was found in group T at the follow-ups. A significant decrease in number of tender sites on the masticatory muscles was found in group T at the follow-ups.
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) of mainly myogenous origin. 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. 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 of tender masticatory muscles in the treatment group (P = .018) compared with the control group.
