Stress Distribution of Periodontal Ligament in Mandibular Second Molar with Different Distal Alveolar Bone Losses

To explore the effect of occlusal adjustment in mandibular second molar with different distal alveolar bone losses on stress distribution periodontal ligament, a left was modelled using finite element analysis based X-ray CBCT scanned images and effects. The equivalent ligament analyzed to study biomechanical properties molars areas losses. Results demonstrate that tissue plays an important role supporting teeth, residual is suggested be retained as much possible clinical treatment.
