A comparative study on the stress distribution in the dentine and cement layer of an endodontically treated maxillary incisor using a Finite Element Analysis (FEA) was presented. The role of post and cement rigidity on reliability of endodontic restorations was also discussed. A chewing static force of 10 N was applied at 125° angle with the tooth longitudinal axis at the palatal surface of the crown. Equivalent stress values ranging from 7.5 MPa (steel) to 5.4 MPa (carbon posts) and 3.6 MPa (cement) and to 2.2 MPa (glass posts) were observed under a static masticatory load of 10N.

Abstract
A comparative study on the stress distribution in the dentine and cement layer of an endodontically treated maxillary incisor using a Finite Element Analysis (FEA) was presented. The role of post and cement rigidity on reliability of endodontic restorations was also discussed. A chewing static force of 10 N was applied at 125° angle with the tooth longitudinal axis at the palatal surface of the crown. Equivalent stress values ranging from 7.5 MPa (steel) to 5.4 MPa (carbon posts) and 3.6 MPa (cement) and to 2.2 MPa (glass posts) were observed under a static masticatory load of 10N.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
