“…Regarding the increased MBF values of 2 and 3 mm thick hard occlusal splints, the results of this study were in line with those of previous studies evaluating 0.6, 1, 2, and 3 mm thick splints [19,21,36]. The present study also found a signi cant increase in MBF on both sides (right/left) during hard occlusal splint therapy, and this increase may be associated with the positive effect of hard occlusal splints on neurobiological regulation of jaw-muscle activity (Figure -2) [37]. While there is only one study in the literature showing that the use of hard splints (1 mm) reduces MBF in patients with bruxism, there are also studies showing that the use of hard splints does not affect MBF (1.5 mm, 2 mm, 3 mm and 6 mm thick splints) [12,21,24,38].…”

“…The choice of biomaterial for occlusal splints has a signi cant effect on the neurobiological regulation of jaw muscle activity during sleep, and splint thickness has been reported to play a role in the incidence of SB [14,37]. In this study, the soft splint groups (S2 and S3) showed the lowest PSQI scores among all groups, indicating an improvement in sleep quality with soft splint use (Figure -3).…”

Objective: To evaluate the short-term effects of hard and soft splints of different thicknesses on maximum bite force (MBF) and sleep quality (SQ) in participants with sleep bruxism (SB).Methods: One-hundred-fteen patients were randomly allocated to ve groups: Groups H2(Hard splint-2 mm), H3(Hard splint-3 mm), S2(Soft splint-2 mm), S3(Soft splint-3 mm), and C (control). Outcomes were MBF (assessed with a digital gnathodynamometer) and SQ (assessed with the Pittsburgh Sleep Quality Index). Measurements were performed at T0 (before the splints), T1 (1-month follow-up), and T2 (2months follow-up). Data were analyzed using one-way ANOVA, Tukey's HSD, and chi-square tests.Results: At T1, the highest MBF values were in group H3 (658.01 ± 22.6 N), while the lowest was in group S2 (585.45 ± 8.68 N). For T2, the highest values belonged to the H3 group (676.85 ± 21.9 N), and the lowest values were observed at group S2 (565.65 ± 10.9 N) (p< 0.05).For SQ, groups S2 and S3 revealed the lowest PSQI values at T1 (9.1; 9.6) and T2 (9; 9.5) (p<0.001).Conclusions: The use of both 2 and 3-mm thick soft splints resulted in a decrease in MBF. The improvement in SQ formed by the soft splint groups occurred in the 1st month and was maintained in the 2nd month.Clinical Relevance: This study provides clinical tips in terms of material type and thickness of the occlusal splint, which should be applied according to the needs of SB patients (such as improving SQ and regulating MBF).

“…Hard stabilization splints significantly reduced the number of sEMG high-activity events per hour of sleep. In contrast, soft occlusal splints do not inhibit jaw muscle activity compared to baseline values [ 39 ]. Despite the advantage of a hard splint, soft splints are used to ease implementation and reduce financial costs to the patient [ 7 ].…”

This study investigates the influence of soft stabilization splints on electromyographic patterns in masticatory and neck muscles in healthy women. A total of 70 healthy women were qualified for the research. The resting and clenching electromyographic patterns of the temporalis (TA), masseter (MM), digastric (DA), and sternocleidomastoid (SCM) muscles were measured using the BioEMG III™ apparatus. The interaction between splint application and resting muscle activity affected the results in all examined muscles except the temporalis muscle. A large effect size was observed in masseter (2.19 µV vs. 5.18 µV; p = 0.00; ES = 1.00) and digastric (1.89 µV vs. 3.17 µV; p = 0.00; ES = 1.00) both-sided RMS activity. Significant differences between the two conditions were observed in all Functional Clenching Indices (FCI) for MM, SDM, and DA muscles. All FCI values for the MM and DA muscles were significantly lower with than without the splint. We observed an increase in all activity indices due to splint application, which suggests a masseter muscle advantage during measurement. The soft stabilization splint influenced resting and functional activity in the MM, SDM, and DA muscles. During tooth clenching, a soft stabilization splint changed the involvement proportions of the temporalis and masseter muscles, transferring the main activity to the masseter muscles. Using a soft stabilization splint did not affect the symmetry of the electromyographic activity of the masticatory and neck muscles.

BACKGROUND AND OBJECTIVES:Temporomandibular disorder is a collective term encompassing a wide range of clinical orofacial joint and muscle problems. The stomatognatic system is part of the postural system, so changes in one system may interfere with the other. This study aimed at observing whether there is change in jaw and head position before and after temporomandibular disorder treatment. METHODS: Participated in the study 16 volunteers, aged above 18 years, of both genders, who looked for assistance in the dentistry course clinic of a Public University, with diagnosis of temporomandibular disorder according to Diagnostic Criteria for Temporomandibular Disorder Research. Volunteers were submitted to X-rays (teleradiography with analysis of cephalometric points); posture in physiologic centric relation was evaluated by computerized photogrammetry and pain intensity was evaluated by the visual analog scale from zero to 10. Patients were evaluated before and after 8 weeks of treatment. RESULTS: Pain has decreased from 6.43±2.84 to 2.17±2.39, before and after treatment, respectively (p<0.05). Vertical head alignment, in initial angle, has changed from 21.84⁰±17.49⁰ to 11.38⁰±14.61⁰ (p<0.05). Jaw position has changed from A-NB (angle indicating mandible-jaw relationship in the anterior posterior direction): 4.95±2.52mm to A-NB: 4.64±2.52mm (p<0.05). CONCLUSION: Muscle temporomandibular disorder changes vertical head alignment and interferes with jaw position.
