Assessment of the fracture resistance in an endodontically treated maxillary central incisor restored prefabricated glass fiber post and custom made cast post using finite element analysis
Sonakshi, Sahil Mogla

Background: The present study was conducted to assess the fracture resistance in an endodontically treated maxillary central incisor restored prefabricated glass fiber post and custom made cast post using finite element analysis. Materials & Methods: The present study was conducted on 50 recently extracted maxillary central incisor. Teeth were divided into 2 groups of 25 each. In group I, endodontically treated central incisor restored with custom-made cast post with a metal ceramic superstructure which was simulated. In group II, endodontically treated central incisor restored with prefabricated glass fiber post with a metal ceramic superstructure which was simulated. Results: In group I, stress value (MPa) of vertical load in dentin was 4.68, in post was 9.72 and in crown was 9.71, horizontal load in dentin was 5.92, in post was 22.5 and in crown was 29.4. In group II, stress value (MPa) of vertical load in dentin was 4.69, in post was 8.61 and in crown was 7.93, horizontal load in dentin was 18.5, in post was 5.2 and in crown was 30.8. Conclusion: Authors found that both groups exhibited similar stress during vertical load. Cast metal post dissipates less stress to the dentin and gives better fracture resistance to the tooth when compared to glass fiber post. Key words: Cast metal post, Fracture resistance, Glass fiber post
