Summary
Children with a lateral forced bite exhibit mandibular displacement towards the affected side. This neuromuscular adaptation occurs even when occlusal interferences are removed, indicating a consistent response to the bite condition.
Area of Science:
- Dentistry
- Neuromuscular Dentistry
- Biomechanics
Background:
- Occlusal interferences can affect mandibular neuromuscular function.
- Understanding these adaptations is crucial for diagnosing and treating bite-related issues.
Purpose of the Study:
- To investigate the adaptive changes in the mandibular neuromuscular system in children with a lateral forced bite.
- To analyze mandibular displacement patterns in the presence of occlusal interferences.
Main Methods:
- Opto-electronic registration technique used to record mandibular movements in the frontal plane.
- 12 children with lateral forced bite performed open-close-clench cycles.
- Mandibular movements were analyzed against intercuspal position, occlusal splints in raised/retruded positions, and splints with retruded stops.
Main Results:
- Mandibular displacement towards the forced bite side was observed consistently.
- Displacement occurred during cycles to intercuspal position and when occlusal contacts were eliminated with flat splints.
- Lateral displacements were measured at maximal contact and at various mouth-opening distances (7, 14, 21 mm).
Conclusions:
- The mandibular neuromuscular system demonstrates a consistent displacement pattern towards the forced bite side in children.
- This adaptation persists even when occlusal interferences are removed, suggesting a stable neuromuscular response.
