ObjectiveAdequate bone support is an essential factor to avoid undue stress to the tooth. This is especially important, when the tooth is endodontically treated and requires a post. The purpose of the present finite element analysis study was to evaluate the stress distribution in endodontically treated teeth with post with different alveolar bone height.Method and materialsA 3D model was fabricated using software to represent an endodontically treated mandibular second premolar restored with titanium post and a full ceramic crown restoration and was analyzed using finite element analysis. A load of 300 N at an angle of 60° to the vertical was applied to the triangular ridge of the buccal cusp in a buccolingual plane. The relationship of alveolar bone height at 2 mm and 4 mm was calculated using von Mises stresses.ResultsThe finite element analysis showed the maximum stresses of 137.43 Mpa in dentin with alveolar bone height of 4 mm as compared to 105.91 Mpa in the model with alveolar bone height of 2 mm from the CEJ.ConclusionStress was observed more in alveolar bone height level of 4 mm from CEJ than 2 mm alveolar bone height level from CEJ.
