Abstract:
Objective To find the characteristics of stress distribution on condyle during different vertical distances of edentulous jaw.Methods Three dimensional finite element models of the mandible and temporomandibular joint were established with the complete dentures in different heights by helix-CT scanned transverse sections.The stress distribution of the condyle was analyzed under load.Results The compressive stress and tensile stress coexisted on the whole condyle with the different vertical distances.The trend of distribution was consistent practically,but the stress presented a large difference on different locum.With the decrease of the vertical distance(from H-2 to H-6),the stress presented a decreasing trend but an increasing trend at H-8.Conclusion Changes in the vertical distance produce different effects of stress on edentulous jaw under the same load.
