Improvement of masticatory function after orthodontic treatment. Two case reports
Summary
Severe malocclusion in growing patients mimics temporomandibular joint dysfunction (TMD) symptoms. Orthodontic treatment normalized masticatory function, improving jaw movements and muscle activity.
Area of Science:
- Dentistry
- Orthodontics
- Biomechanical Engineering
Background:
- Temporomandibular joint dysfunction (TMD) is characterized by altered masticatory function.
- Key alterations include infrequent achievement of intercuspal position (ICP), increased vertical displacement, and suppressed isometric muscle contraction during closure.
Observation:
- Two growing patients with severe malocclusion presented with functional alterations similar to TMD.
- These patients exhibited reduced ICP achievement, abnormal vertical displacement, and altered muscle contraction patterns.
Findings:
- Orthodontic treatment was initiated for the severe malocclusion in both patients.
- Following orthodontic intervention, significant normalization of masticatory function was observed.
Implications:
- Severe malocclusion can manifest with functional deficits mimicking TMD.
- Orthodontic treatment may effectively restore masticatory function in such cases.
- This highlights the importance of addressing malocclusion for overall oral health and function.
