Resumen
La presente investigación tuvo como objetivo comparar in vitro la adaptación interna de coronas de disilicato de litio de distintos espesores en 0.5 mm y 1 mm, elaboradas mediante tres técnicas diferentes. La muestra estuvo compuesta por 54 coronas de las cuales 27 coronas fueron para un espesor de 0.5 mm empleando el método convencional, fresado e impreso 3D y 27 coronas para un espesor de 1 mm con sus diferentes métodos. El estudio evaluó la adaptación interna in vitro de coronas de disilicato de litio con espesores de 0,5 mm y 1 mm, elaboradas mediante técnicas convencional, impresa y fresada. En general, se hallaron diferencias significativas entre los grupos (p=0,013). Al analizar solo las coronas de 0,5 mm, también se observaron diferencias significativas según la técnica (p=0,005). En cambio, para las coronas de 1 mm no hubo diferencias significativas (p=0,167). Finalmente, al comparar ambos espesores (0,5 y 1 mm) dentro de cada técnica, tampoco se encontraron diferencias significativas. Un mejor ajuste interno reduce el riesgo de filtraciones, caries secundarias y fracaso restaurador.
The present study aimed to compare the in vitro internal adaptation of lithium disilicate crowns with different thicknesses: 0.5 mm and 1 mm, manufactured using three different techniques. The sample consisted of 54 crowns, of which 27 were 0.5 mm thick using conventional, milled, and 3D-printed methods, and 27 were 1 mm thick using different methods. The study evaluated the in vitro internal adaptation of lithium disilicate crowns with thicknesses of 0.5 mm and 1 mm, manufactured using conventional, milled, and milled techniques. Overall, significant differences were found between groups (p=0.013). When analyzing only the 0.5 mm crowns, significant differences were also observed depending on the technique (p=0.005). However, no significant differences were observed for the 1 mm crowns (p=0.167). Finally, when comparing both thicknesses (0.5 and 1 mm) within each technique, no significant differences were found. A better internal fit reduces the risk of leakage, secondary caries, and restorative failure, benefiting both the clinician and the patient. Furthermore, the results contribute to the development of more robust criteria for choosing the optimal method and thickness when restoring teeth with lithium disilicate crowns.
