Finite element biomechanical comparison of bone-driven and occlusion-driven fibular flap positioning in lateral segmental mandibular reconstruction

Key Points

• More favorable stress-strain conditions occur with a higher position of the bone component in fibular flaps, enhancing osseointegration.
• Optimal load distribution in the higher alveolar-crest position may lead to better long-term function.
• The study highlights the importance of flap positioning in promoting effective biomechanical properties for successful reconstruction.
• Biomechanical analysis shows key differences in stress environments that can influence surgical outcomes and patient's recovery.
