“…In-vitro testing of restorations under statical load without artificial aging can provide information on indication and clinical limitations of a treatment modality. However, artificial aging has been considered as a reliable tool to predict clinical durability of restorations before recommending for clinical use (14,20). In the present study, all specimens were subjected to cyclic loading and thermal cycling to the mechanical behavior of different restorations under clinically approximated conditions.…”

PurposeThe purpose of this study was to investigate the fracture resistance and failure modes of different non-aged and aged abutment/crown systems. Materials and MethodsOne hundred dental implants (diameter 4.3 mm and length 11.5 mm) were restored with five abutment/crown systems: G1: a lithium disilicate hybrid abutment crown, G2: a lithium disilicate crown cemented on a lithium disilicate hybrid abutment, G3: a lithium disilicate crown cemented on a zirconia hybrid abutment, G4: a direct veneer porcelain layering on a zirconia hybrid abutment, and G5: a lithium disilicate crown cemented on a prefabricated all-zirconia abutment. Each group was divided into two groups (n=10) as control (non-aged) and thermomechanically aged. The fracture resistance test was performed. Failures during the aging process and after the fracture resistance test were examined. ResultsBoth of the factors (restoration type and aging) affected the fracture resistance values and there was not an interaction between the factors (p>0.05). When fracture resistance values were compared regardless of aging, the highest values were observed in G3 and G4, respectively (p<0.05). When comparing the fracture resistance values, regardless of the restoration type, the aged group showed a significant lower fracture resistance value than control group (p<0.05). ConclusionA titanium base enhanced the fracture resistance of zirconia abutments. Thermomechanical aging decreased the fracture resistance of the tested ceramic abutment/crown systems. The major failure mode was the abutment fracture.

Introduction: Temporary restorations produced with a 3D printer have become very popular recently. There are limited studies in the literature comparing 3D printing and traditionally produced temporary materials. Objectives:The aim of this study is to examine the color and roughness changes of different temporary mate rials produced by a 3D printer and the traditional method after being kept in coffee, and also to evaluate the effect of the polishing process applied to the surfaces. Material and methods: Two types of 3D printing resin and a conventional autopolymerized PMMA material were selected. Half of the samples in each group were polished with polishing paste (n = 15). The first color values and surface roughness were measured, then samples were kept in coffee. 48 hours later, the second color measure ments of the samples were made with spectrophotometer and ∆E00 values were calculated. Surface roughness values were measured with a profilometer device. Data were analyzed with the twoway analysis of variance and Tukey test. The relationship between roughness and color change in the coloring process was evaluated by Spear man correlation analysis (p < 0.05). Results: According to twoway ANOVA analysis the color change between the materials and the color change in the polishing state of the surface were found to be statistically significant. The ΔE values listed from the highest to the lowest were as follows: unpolished PMMA > polished PMMA > polished temporary 3D resin > unpolished temporary 3D resin > unpolished standard 3D resin group > polished standard 3D resin. Conclusions: The conventionally produced PMMA group was the material that underwent the most color change. From the materials produced by 3D printing, the temporary resin is more colored than the standard resin. A significant relationship was found between color change and roughness change. Less color change was found on polished surfaces.

“…Obtaining a model of good quality that true to its original is extremely important for the success of the treatment; different types of materials and impression techniques have been used over the years to achieve this desired accuracy [1]. Since the introduction of dental CAD/CAM systems, the adaptation of restorations may be improved by combining intraoral scanning and digital milling [2,3].…”

Our aim in this follow-up in vitro study was to compare differences in marginal fit of inlays fabricated by CAD/CAM technique, using 2 different types of materials (one type of ceramic and one type of hybrid ceramic) and 2 different types of scanning: intraoral scanning (we use quotation marks because of the lack of a true intraoral environment) and model scanning, both performed on a Frasaco Typodont model. Marginal fit measurement was carried out with an electronic microscope at 1000x magnification. Our results proved to be better in the case of the ceramic we used, while model scanning proved to be more accurate than intraoral scanning. The best combination we obtained in terms of marginal fit was found when using ceramic and model scanning.
