Pantographic records on TMJ dysfunction subjects treated with occlusal splints: a progress report
The Journal of Prosthetic Dentistry
|April 1, 1975
Summary
Occlusal bite splints improved TMJ dysfunction symptoms and muscle activity in subjects. However, reproducible mandibular border movements did not significantly improve, suggesting further investigation into treatment duration and type is needed.
Area of Science:
- Dentistry
- Neuromuscular Dentistry
Background:
- Temporomandibular Joint (TMJ) dysfunction often presents with impaired mandibular border movements.
- Electromyography (EMG) and pantography are key diagnostic tools for assessing TMJ function.
Purpose of the Study:
- To evaluate the effectiveness of occlusal bite splints in treating TMJ dysfunction.
- To assess changes in muscle activity and mandibular border movements following treatment.
Main Methods:
- Five subjects with TMJ dysfunction were treated with occlusal bite splints.
- Mandibular border movements were recorded using a pantograph.
- Muscle activity was analyzed using electromyography (EMG).
Main Results:
- Subjects reported relief of clinical symptoms after one month of treatment.
- EMG showed improved muscular activity in most subjects.
- Pantographic recordings indicated limited improvement in reproducible mandibular border movements.
Conclusions:
- Occlusal bite splints may alleviate TMJ symptoms and improve muscle activity.
- The duration and specific type of occlusal splint therapy require further investigation for optimizing mandibular movement restoration.
- Further research is warranted to explore long-term effects and treatment variations.
