Maximal Mouth Opening

This retrospective study investigated the effects of combining manual therapy and acupuncture on the pain and maximal mouth opening (MMO), which were associated with temporomandibular joint dysfunction (TMD). The 49 TMD patients (15 men, 34 women; mean age = 30.47 years, SD = 13.52 years) were treated with a combination of acupuncture and manual therapy two or three times a week at the hospital. The pain and maximal mouth opening were assessed before and after 1 and 4 weeks of treatment. The combination therapy produced significant changes in pain levels ( p < 0.001) and mouth opening ( p < 0.001). All pairwise non-parametric comparison showed a significant improvement in pain ( p < 0.05 for all pairs) and MMO ( p < 0.05 for all pairs). These findings suggest that combining manual therapy and acupuncture decreases the pain level and increases the MMO of TMD patients. However, future studies should further investigate the efficacy of combined treatment on TMD with more rigorous randomized clinical trials.

Invasive Intervention

Abstract: Introduction: Derangement of the temporomandibular joint complicates everyday life, due to the masticatory malfunction and the continuous pain sensation of the head and facial region. The therapy is multidisciplinary and varying. In case of the inefficiency of conservative therapy, minimally invasive intervention is needed with intraarticular injection. Aim: The aim of our study was to examine whether hyaluronic acid injection is more beneficial compared to corticosteroid in 37 joints. We also examined whether the efficacy of the therapy is influenced by hyaluronic acid molecular weight and the used protocol. Method: Wilkes stage, maximal mouth opening and the Visual Analogue Scale were determined pre-operatively and 6 months later. Corticosteroid application was performed once, hyaluronic acid was injected on a weekly bases 3 times in a row, by use of low (6–10 × 105 dalton) or high molecular weight (24–36 × 105 dalton) preparations. Results: The medical state of the patients treated with corticosteroid temporarily improved, but the symptoms returned. Due to hyaluronic acid treatment, significant improvement was revealed in all parameters (pwilkes<0.0001; pmouth-opening = 0.0002; pVAS<0.0001). There was no significant relapse (T = 2.05). The third administration of hyaluronic acid resulted in a significant improvement of the Visual Analogue Scale compared to the first and second injection (T3.–1. = 20.37; T3.–2. = 9.57). Conclusions: Comparing the two agents we can state that hyaluronic acid was significantly more effective and its application for three times seems to be the most effective treatment decreasing the symptoms. The high molecular weight solution was more effective in increasing mouth opening. In contrast to hyaluronic acid, corticosteroid had no prolonged effect in higher Wilkes stages.

Common signs and symptoms of TMD include masticatory muscle pain, TMJ sounds, limited mouth opening, and deviations in mandibular movements. Treatment generally involves some combination of occlusal splints, physiotherapy, relaxation therapy, pharmacological intervention, arthroscopic surgery, education, and behavioural counselling. One randomized controlled trial indicated that an occlusal deprogramming splint is more effective than other methods in treating TMD, although another study produced contradictory results. Measurements of the radiographic joint space a radiolucent area between the mandibular condyle and the temporal bone were introduced by Ricketts to describe condylar position. The clinical significance of condyle-fossa relationships in the TMJ is controversial, but several studies have suggested an association between eccentric condylar position and TMD. This chapter describes key changes in the condyle-fossa relationship after the use of an occlusal deprogramming splint in patients with TMD.

Method Of Constant Stimuli

The purpose of this study was to determine whether different extents of mouth opening affect normal subjects' ( N = 24; 12 women, 12 men) ability to discriminate differences in their interincisor bite force. Three mouth openings were selected including 50, 70, and 90 percent of maximum opening for each subject. Bite force was measured using a specially designed strain gauge scale which permitted subjects to monitor visually when their biting force equalled a preset resistance. Resistance forces of 500 and 1000 gm. were selected as standards. The procedure involved the use of a modified method of constant stimuli in which each subject was presented with a series of paired resistance settings, one at a time—the first resistance setting being the standard and the second resistance was the comparator. This paired-comparisons procedure was continued until the subjects' difference limen (DL) value (the threshold of discrimination between two forces) could be established. An analysis of variance yielded no significant differences in subjects' ability to discriminate bite force as a function of mouth opening.
