Maximum compressive stress analysis in upper central incisors rehabilitated with fiberglass posts and three types of crowns. A study with the finite element method.Análisis de máxima tensión compresiva en incisivos centrales superiores rehabilitados con postes de fibra de vidrio y tres tipos de coronas. Un estudio con método de elementos finitos.Chávez Vela, Mayra J. López Flores, Ana I. cerámicascoronasanálisis de elementos finitosmáxima tensión compresivaceramicscrownsfinite element analysismaximum compressive stressObjective: To evaluate the maximum compressive stress in maxillary central incisors restored with fiberglass posts and three types of crowns by the FEM finite element method. Materials and methods: The study was a virtual, descriptive, and laboratory trial. Three virtual models were made using the SolidWorks 2017 software from upper central incisors rehabilitated with fiberglass posts and a metal-ceramic crown, a monolithic lithium disilicate crown, and a zirconium-ceramic crown. They were then subjected to an oblique occlusal load of 150N with an angulation of 45°, distributed towards the palatal aspect. The stress analysis proceeded by comparing the maximum, minimum, and equivalent von Mises stresses. Results: The maximum compressive stress was found at the cervical level in the vestibular area of each of the crowns. Zirconium-ceramic crown (Design 3) was the one with the highest compressive stress with 73.89 MPa, followed by Lithium Disilicate crown (Design 2) with 63.42 MPa and the metal-ceramic crown (Design 1) with 48.4 MPa. Conclusion: The zirconium-ceramic crown better distributes the stress along the tooth since, due to its rigidity, it absorbs the stresses that are concentrated especially in the cervical area, which could indicate that it is the most appropriate option to rehabilitate endodontically treated teeth.Objetivo: Evaluar la máxima tensión compresiva en incisivos centrales superiores restaurados con postes de fibra de vidrio y tres tipos de coronas por método de elementos finitos MEF. Materiales y métodos: El estudio fue un ensayo de laboratorio virtual y descriptivo. Se confeccionaron 3 modelos virtuales mediante el programa SolidWorks 2017, a partir de incisivos centrales superiores rehabilitados con postes de fibra de vidrio y corona metal-cerámica, corona de disilicato de litio monolítica y corona de zirconio-cerámica; luego, estos fueron sometidos a una carga oclusal oblicua de 150 N con una angulación de 45°, distribuida hacia la cara palatina. El análisis de las tensiones se realizó mediante la comparación de las tensiones máximas, mínimas y equivalentes de Von Mises. Resultados: La máxima tensión compresiva se encontró a nivel cervical en la zona vestibular de cada una de las coronas, siendo el diseño 3 (corona de zirconio-cerámica) el que presentó mayor tensión compresiva, con 73,89 MPa, seguido por el diseño 2 (corona de disilicato de litio), con 63,42 MPa, y el diseño 1 (corona metal-cerámica), con 48,4 MPa. Conclusión: La corona zirconio-cerámica distribuye mejor la tensión a lo largo del diente, ya que, por su rigidez, absorbe las tensiones que se concentran especialmente en cervical, lo que podría indicar que es la opción más apropiada para rehabilitar dientes tratados endodónticamente.Carrera de Estomatología de la Universidad Científica del Sur2022-09-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.cientifica.edu.pe/index.php/odontologica/article/view/130110.21142/2523-2754-1003-2022-125Revista Científica Odontológica; Vol. 10 Núm. 3 (2022); e125Revista Científica Odontológica; Vol. 10 No. 3 (2022); e1252523-27542310-2594reponame:Revistas - Universidad Científica del Surinstname:Universidad Científica del Surinstacron:CIENTÍFICAspahttps://revistas.cientifica.edu.pe/index.php/odontologica/article/view/1301/1053info:eu-repo/semantics/openAccessoai:revistas.cientifica.edu.pe:article/13012022-10-10T18:18:07Z |
