dc.description | El objetivo de este estudio fue evaluar y comparar la resistencia a la fractura de una prótesis fija unitaria, utilizando un material CAD/CAM PMMA y dos materiales impresos (3DPPa y 3DPPb). Se utilizó un tipodonto con una preparación específica para una corona completa; se tomó una impresión digital con un escáner de última generación (PrimeScanTM, DentsplySironaTM, Nueva York, NY, EE.UU.), y se diseñó una restauración de cobertura completa utilizando una propuesta de diseño biogenérico mediante un software específico (InLAB 22.1, Dentsply-Sirona, NY, EE.UU.). Se prepararon 60 coronas, divididas en tres grupos según el material: 3DPPa (n = 20), 3DPPb (n = 20), ambas impresas en 3D a partir del archivo .STL con una resolución de 50 μm, y PMMA (n = 20) fresado-derivado, que fueron sometidas a un proceso de termociclado. Para determinar la resistencia a la fractura se utilizó una máquina universal de ensayos (Universal/Tensile Testing Machine, Autograph AGS-X Series) con software integrado (TRAPEZIUM LITE X) equipada con una célula de carga de 20 kN. Se encontraron diferencias significativas mediante la prueba de Kruskal-Wallis y comparaciones múltiples (p < 0,05) en la resistencia a la fractura entre los materiales. La resistencia a la fractura para el material PMMA fue mayor, y la desviación estándar fue menor (x = 1427,9; sd = 36,9 N) en comparación con las impresiones 3DPPa (x = 1231; sd = 380,1 N) y 3DPPb (x = 1029,9; sd = 166,46 N). Las restauraciones del grupo derivado del fresado mostraron una resistencia media a la fractura superior a la de las restauraciones provisionales obtenidas de los grupos impresos. No obstante, los resultados demostraron que los tres materiales analizados en restauraciones unitarias son capaces de soportar las fuerzas masticatorias medias. | en_US |
dc.description.abstract | The aim of this study was to evaluate and compare the fracture resistance of a single- unit fixed prosthesis, using a CAD/CAM PMMA material and two printed materials (3DPPa and 3DPPb). A typodont with a specific preparation for a full crown was used; a digital impression was made with a state-of-the-art scanner (PrimeScanTM, Dentsply-SironaTM, New York, NY, USA), and a full coverage restoration was designed using a biogeneric design proposal by means of specific software (InLAB 22.1, Dentsply-Sirona, NY, USA). Sixty crowns were prepared, divided into three groups according to the material: 3DPPa (n = 20), 3DPPb (n = 20), both 3D-printed from the .STL file with a resolution of 50 μm, and PMMA (n = 20) milledderived, which were subjected to a thermocycling process. A universal testing machine (Universal/Tensile Testing Machine, Autograph AGS-X Series) with integrated software (TRAPEZIUM LITE X) equipped with a 20 kN load cell was used to determine the fracture resistance. Significant differences were found by Kruskal–Wallis test and multiple comparisons (p < 0.05) in fracture resistance between materials. The fracture resistance for the PMMA material was higher, and the standard deviation was lower (x = 1427.9; sd = 36.9 N) compared to the 3DPPa (x = 1231; sd = 380.1 N) and 3DPPb (x = 1029.9; sd = 166.46 N) prints. The restorations from the milled-derived group showed higher average fracture resistance than the provisional restorations obtained from the printed groups. However, the results demonstrated that all three materials analyzed in single-unit restorations are capable of withstanding the average masticatory forces. | en_US |
