Summary

Finite element analysis revealed that concentrated loads on molars generate significantly higher stresses than distributed loads. This highlights the biomechanical impact of load application on mandibular stress distribution.

Area of Science:

  • Biomechanical Engineering
  • Dental Mechanics
  • Finite Element Analysis

Background:

  • Understanding stress distribution in the mandible is crucial for dental implantology and prosthodontics.
  • Previous studies have utilized finite element analysis (FEA) to model mandibular biomechanics.

Purpose of the Study:

  • To investigate the stresses and displacements in a mandibular quadrant under different loading conditions using FEA.
  • To compare the biomechanical response to distributed versus concentrated loads on molars and premolars.

Main Methods:

  • A two-dimensional finite element model of a mandibular quadrant was developed.
  • A 100 N load was applied in three configurations: distributed on the second molar, concentrated at 30 degrees on the second molar, and distributed on the second premolar and second molar.

  • Material properties (modulus, Poisson's ratio) were based on accepted values for teeth, periodontal ligaments, and bone.

    • Main Results:

    • Uniformly distributed loads on the second molar resulted in primarily compressive (sigma min) and tensile (sigma max) stresses.
    • Concentrated loads at 30 degrees to the vertical generated stresses 3-5 times greater and less uniform than distributed loads.
    • Concentrated loads induced higher bending stresses and greater maximum tensile stresses (sigma max).

    Conclusions:

    • The manner of load application significantly influences stress patterns and magnitudes within the mandibular quadrant.
    • Concentrated, angled forces on posterior teeth result in considerably higher biomechanical stress than distributed forces.
    • These findings have implications for designing dental restorations and understanding occlusal forces.
