Summary of Research Paper on “Influence of Occlusal Splint on Mandibular Movements in Patients with Bruxism: a Comparative Pilot Study”

 

The research paper titled "Influence of Occlusal Splint on Mandibular Movements in Patients with Bruxism: a Comparative Pilot Study" examines the impact of occlusal splint treatment on mandibular movements and condyle position in patients with bruxism.

 

The main research question is to determine whether the use of occlusal splints affects mandibular border movements and condyle position in patients with bruxism.

 

The study follows a pilot study design, with a sample size of 9 subjects diagnosed with bruxism and 9 subjects in the control group. All subjects were adults without prosthetic restorations, previous orthodontic treatments, a systemic disease, or previous surgical interventions in the temporomandibular joint.

 

Data collection was done using an Arcus Digamma II ultrasound device, which recorded mandibular movements. Measurements of incisal opening, condyle opening, and laterotrusion were taken at various intervals during an 8-week period. The position of the condyle during protrusion, laterotrusion, and in the centric relation position was also analyzed.

 

The key findings of the study show that wearing occlusal splints for 8 weeks resulted in increased mandibular movements in subjects with bruxism. The condyle position during various movements also showed significant changes after occlusal splint treatment.

 

Statistical analyses were performed to determine the significance of the changes observed in mandibular movements and condyle position. The t-test and χ2 test were used, with a significance level of p < 0.05.

 

In the discussion section, the results are analyzed and interpreted in relation to the research question and objectives. The implications and significance of the findings are discussed, highlighting the impact of occlusal splint treatment on mandibular movements and condyle position in patients with bruxism.

 

The study acknowledges certain limitations, such as the small sample size and the use of a pilot study design. Further research is needed to validate the findings and assess the long-term effects of occlusal splint treatment on mandibular movements in patients with bruxism.

 

In conclusion, this comparative pilot study provides evidence of the influence of occlusal splint treatment on mandibular movements and condyle position in patients with bruxism. The findings contribute to the understanding of the effects of occlusal splints in managing bruxism and highlight the potential benefits of this treatment approach in improving mandibular movements in patients with bruxism.
