Abstract

Teeth that have undergone endodontic treatment often lose significant structure, requiring strong and durable restorations to prevent clinical failure and support long-term function. This study aimed to evaluate the effect of post-curing time on the hardness, diametral tensile strength (DTS), and water sorption of 3D-printed resin composites. An experimental study was conducted using 80 disc-shaped resin composite specimens divided into four groups based on post-curing time duration (5 minutes, 10 minutes, no curing, and control). Hardness was measured using the Vickers Hardness test, DTS with a Universal Testing Machine, and water sorption through immersion in artificial saliva. Hypothesis testing was performed using ANOVA and Post Hoc Tamhane tests. The results showed that increasing the post-curing time significantly improved hardness but did not affect DTS and water sorption. The group with 10 minutes of post-curing time achieved the best results in hardness improvement. The findings indicate that post-curing time positively influences the mechanical and physical properties of resin composites, particularly the hardness of 3D-printed materials. This process enables better polymer densification, resulting in stronger materials resistant to degradation in the oral environment. The duration of post-curing time significantly contributes to optimizing the mechanical and physical properties of 3D-printed resin composites, making it an essential step in manufacturing restorations for the long-term success of dental restorations.

Abstract

Marginal and internal fit accuracy are critical factors for the success of indirect restorations. With advancements in Liquid Crystal Display (LCD)-based 3D printing technology, this study evaluates the effects of build angle and preparation margin design on the accuracy of 3D-printed resin composite overlays. This study aims to analyze differences in the marginal and internal fit accuracy of 3D-printed resin composite overlays based on build angle (150° and 180°) and preparation margin designs (shoulder and functional cusp bevel). This experimental study used 40 overlay samples divided into four groups based on combinations of build angle and preparation margin design. Marginal and internal fit accuracy was assessed using the silicone weight technique, and using the silicone replica technique with a digital optical microscope. Data were statistically analyzed using Two-way ANOVA and Post Hoc Tukey tests. Build angle statistically influenced both marginal and internal fit accuracy (p<0.05). The 180° angulation group showed better results compared to 150°. Preparation margin design did not significantly affect internal fit accuracy, although the functional cusp bevel design exhibited larger marginal gaps than the shoulder design in specific measurements. Conclusion: The build angle affects the marginal and internal fit accuracy for 3D-printed resin composite overlays using the LCD method and 180° yields better marginal and internal fit accuracy. Preparation margin design did not significantly affect internal fit accuracy.
