    Summary

    Balancing-side interferences in dental restorations significantly reduce short-term masticatory performance, impacting food particle size. This highlights a common technical failure

    Area of Science:

    • Dental occlusion
    • Masticatory system biomechanics
    • Biomaterials science

    Background:

    • Occlusal interferences, particularly balancing-side interferences, are common issues in dental restorations.
    • While their effects on jaw kinematics and electromyographic activity (EMG) are known, their impact on masticatory performance remains less understood.

    Purpose of the Study:

    • To investigate the hypothesis that balancing-side interferences significantly reduce masticatory system performance.
    • To quantify the effect of simulated balancing interferences on food particle size reduction.

    Main Methods:

    • Twenty-one healthy subjects chewed standardized silicone cubes under three conditions: natural dentition, structured occlusal splints, and splints with balancing interferences.
    • Masticatory performance was assessed by analyzing particle size distribution (X(50)-values) using a validated scanning procedure.

  • Electromyographic activity (EMG) of masticatory muscles and incisal movement path (IMP) were recorded simultaneously.

    • Main Results:

    • Balancing-side interferences significantly increased X(50)-values (indicating poorer performance) compared to natural dentition and structured splints (P < 0.01).
    • No significant differences in X(50)-values were found between natural dentition and structured splints (P > 0.05).
    • Total muscle work (TMW) and incisal movement path (IMP) showed no significant differences across the three conditions (P > 0.05).

    Conclusions:

    • The study confirms that balancing-side interferences significantly reduce short-term masticatory performance.
    • This finding underscores the clinical relevance of occlusal balancing-side interferences as a technical failure in dental restorations.
    • Further research is needed to determine the long-term effects and impact on patients with reduced adaptive capacity.
