Summary
Introducing balancing-side interferences temporarily altered mandibular movements in healthy subjects. However, the neuromuscular system adapted over one week, suggesting resilience to these occlusal changes.
Area of Science:
- Dental occlusion
- Masticatory system biomechanics
- Neuromuscular adaptation
Background:
- Occlusal interferences can affect masticatory function.
- Understanding the neuromuscular response to occlusal changes is crucial for dental health.
- Previous research has explored short-term effects, but long-term adaptation requires further investigation.
Purpose of the Study:
- To examine how nonworking-side occlusal interferences impact mandibular movements.
- To assess the signs and symptoms of masticatory system dysfunction.
- To determine the adaptive capacity of the neuromuscular system to experimental interferences.
Main Methods:
- An experimental balancing-side interference was introduced in 12 healthy participants.
- Mandibular masticatory movements were recorded and analyzed.
- Signs and symptoms of masticatory dysfunction were monitored over a one-week period.
Main Results:
- Individual responses to the interference varied significantly among subjects.
- Immediate insertion of the interference caused significant changes in some mandibular movement variables.
- Evidence of neuromuscular system adaptation to the interference was observed by the end of the week.
Conclusions:
- The masticatory system exhibits adaptive capabilities in response to occlusal interferences.
- Short-term occlusal changes can transiently affect mandibular kinematics.
- Neuromuscular adaptation plays a key role in mitigating the effects of balancing-side interferences over time.
