Finite element analysis of mandibular biomechanical stress under vertical loading in models with angular defects

Key Points

• Mechanical stress significantly increases in mandibular models with angular defects under vertical loading, influencing design considerations.
• The maximum stress observed was around 180 MPa, indicating critical thresholds in mechanical integrity.
• Assessment using finite element analysis provides detail on how angular defects influence stress distribution in mandibles.
• Findings highlight the need for improved surgical planning and reconstruction strategies in dentistry.
