| Resumen : | Los materiales dentales en la actualidad nos permiten ofrecer una alta gama de tratamientos en donde la elección que realice el profesional debe estar enmarcado siempre a una restauración que persista durante el paso del tiempo sin perder sus características y que presente una resistencia elevada a la compresión, por esta razón el uso del disilicato de litio ha consistido una opción ideal para un sin número de casos en donde se busca un tratamiento que involucre una elevada resistencia sin perder sus aspectos estéticos... |
| Descripción : | Dental materials currently allow us to offer a high range of treatments where the choice made by the professional should always be framed to a restoration that persists over time without losing its characteristics and that present a high resistance to compression, For this reason the use of lithium disilicate has been an ideal option for a number of cases where a treatment involving a high resistance is sought without losing its aesthetic aspects. In this way the investigation is based on determining if the veneer with a certain preparation in the incisal sector increases the resistance of the same, through the in vitro samples with the three terminations used (vis a vis, incisal reduction of 1mm, reduction Incisal with a palatal termination as a chamfer) will allow to obtain a virtual study model, which was managed with the data that are obtained with the previous samples, and with the help of finite element were analyzed allowing to know the behavior against Each of the loads subjected to the virtual samples, in this way it is obtained that the termination that offers greater resistance to the fracture was the one that presents / displays an incisal reduction of 1mm (3018 N), nevertheless it is prudent to understand that the distribution of the Efforts that could be analyzed thanks to the finite element demonstrates that before the application of a vertical force the termination Which has a 1 mm incisal reduction (7428 MPa), followed by the palatal incision termination that has an incisal reduction and a chamfer finish on the palatal face (5212.89 MPa), and the termination at Vis vis vis (4872.43 MPa). In turn, for the distribution of the virtual samples to the horizontal forces corresponds to the same order: incisal reduction of 1 mm (7956.06 MPa), followed by the termination that has an incisal reduction and a chamfer finish on the palatal face (6416.09 MPa), and the termination visa- vis (4680.85 MPa). With the obtaining of this data we can define that the finish that is recommended to choose before the preparation of veneers is the one that presents an incisal reduction of 1mm. |
