Statement Of Problem: Research on the color and translucency properties of 3-dimensionally (3D) printed definitive resins and the effect of coffee thermocycling on these properties is lacking.
Purpose: The purpose of this in vitro study was to investigate the effect of coffee thermocycling on the color and translucency parameters of the milled and 3D printed materials used for definitive restorations.
Material And Methods: Plate-shaped specimens (12×12×1 mm) of 3 milled (IPS e.
Statement Of Problem: Studies on the energy absorption characteristics by means of elastic and plastic material deformation of interim materials are lacking.
Purpose: The purpose of this in vitro study was to compare the effect of different thermocycling periods on the flexural strength (σ), resilience (U), and toughness (U) of conventionally polymerized, computer-aided design and computer-aided manufacturing (CAD-CAM) milled, and 3-dimensionally (3D) printed interim materials.
Material And Methods: Rectangular specimens (n=30 for each material) were fabricated from autopolymerized polymethyl methacrylate (PMMA), bis-acryl resin (Bis-acryl), CAD-CAM polymethyl methacrylate-based polymer (CAD-CAM/Milled), and 3D-printed composite resin (3D-Printed).
Statement Of Problem: Studies on the surface roughness and color stainability of interim prostheses produced with 3-dimensional-printing technology are lacking.
Purpose: The purpose of this in vitro study was to investigate the effect of different surface treatments on the surface roughness and stainability of 3-dimensionally printed, computer-aided design and computer-aided manufacturing (CAD-CAM) milled and conventional interim materials.
Material And Methods: A total of 320 specimens were fabricated from autopolymerizing polymethyl methacrylate, bis-acryl composite resin, CAD-CAM polymethyl methacrylate resin (milled), and 3-dimensionally printed composite resin (printed) (n=80).
The purpose of this study was to investigate the shear bond strength (SBS) of ceramic discs luted to differently etched enamel and dentin surfaces. Occlusal surfaces of 64 carious-free human molars and vestibule surfaces of 64 first maxillary incisors were ground to get flat superficial dentin and flattened enamel respectively. After generating 4 groups according to the surface etching method (37% orthophosphoric acid, Er:YAG laser-contact handpiece/scanning handpiece (1 or 2 times of scanning)), ceramic discs were luted to the surfaces with adhesive resin cement (Variolink N, Vivadent Ets.

Materials And Methods: Specimens of ceramic LV (CLV-IPS E.max Press), hand-layered composite LV (hand-layered laminate veneer [HLV]-Tetric N-Ceram), and prefabricated composite LV (prefabricated laminate veneer [PLV]-Componeer Coltene) were prepared as discs (n = 10).
Statement Of Problem: Fixed complete dentures (FCDs) have been used in the treatment of completely edentulous patients for over 40 years. However, few reports have investigated misfit values and strain distribution in the context of FCDs fabricated with new technologies.
Purpose: The purpose of this in vitro study was to evaluate misfit values and strain distribution in FCDs and their relation to the fabrication technique of the cobalt-chromium (Co-Cr) metal framework.
