Summary

The aim of this randomized controlled trial was to assess the efficacy of stabilization splint treatment on TMD-related facial pain and oral health-related quality of life during a one-year follow-up. Eighty TMD patients were randomly assigned to two groups: splint group (n=39) and control group (n=41). The patients in the splint group were treated with a stabilization splint and received counseling and instructions for masticatory muscle exercises. The controls received only counseling and instructions for masticatory muscles exercises.

The outcome variables were the intensity of facial pain (as measured with visual analogue scale, VAS), patients' subjective estimate of symptoms and treatment outcome, as well as Oral Heath Impact Profile (OHIP)-14. The differences in variables between the groups at each follow-up points (1 month, 3 months, 6 months and 1 year after baseline) were analyzed using regression models. Group status and presence of psychosocial symptoms were included as the explanatory factor and baseline VAS, gender, age, length of treatment and general health status as confounders.

Interventions

DEVICE

Stabilization splint treatment

The stabilization splints were made of heat-cured acrylic by the same dental technician. The occlusion of the splint was defined in the centric relation occlusion using wax (Astynax, Associated Dental Products Ltd, UK). The patients were instructed to use the splint every night during the course of the study. The patients were instructed to perform a standardized program for masticatory muscle exercises. At the beginning of the training program, active mouth openings, laterotrusive movements and protrusive movements were performed. The mandible was held in the maximal positions for a few seconds on each movement. Thereafter, these movements were made towards resistance (using the patient's own fingers). After jaw exercises, the patients were suggested to open the jaw wide, stretching it with fingers a few times for 10 to 20 seconds. These movements were repeated 7 to 10 times per training session, and the sessions were performed 2-3 times per day.
