“…In two-body wear, the wear rate is typically lower, and the wear patterns are predictable. The wear mechanism can be influenced by factors such as load, surface roughness, and material properties [ 87 , 88 ].…”

(1) Background: The objective of this in vitro study is to evaluate the marginal accuracy of crowns created by CAD/CAM. (2) Methods: A customized chrome-cobalt (Cr-Co) implant abutment simulating a maxillary right first molar was fixed in a hemi-maxillary stone model and scanned. In total, 27 crowns were fabricated, including 9 lithium disilicate crowns, 9 composite crowns, and 9 zirconia crowns. The measurements were determined by scanning electron microscopy. Descriptive analysis was performed using the mean and standard deviation, while the Kruskal–Wallis test was performed to determine whether the marginal discrepancies were significantly different between each group (p < 0.05). (3) Results: The lowest marginal gap value was reported for zirconia (21.45 ± 12.58 µm), followed by composite (44.7 ± 24.96 µm) and lithium disilicate (62.28 ± 51.8 µm). The Kruskal–Wallis tests revealed a statistically significant difference (p-value < 0.05) in the mean marginal gaps between different materials. (4) Conclusions: The proposed digital workflow can be a viable alternative for fixed prosthetic rehabilitations. The best performance in terms of marginal gap was achieved by zirconia crowns, but all three materials demonstrate marginal closure below the clinically accepted threshold value (120 µm). Clinical significance: although significant differences were reported, the investigated CAD/CAM materials showed clinically acceptable marginal gaps.

“…The advancements in our understanding of chewing simulation testing and wear processes, as well as how they lead to material failures in the real oral environment, were emphasized in recent research. Additionally, the properties of chewing simulators capable of simulating the intraoral tribological mechanism in a laboratory context have been examined [122][123][124]. The impact of temper-ature on the visco-elastic characteristics of composite resins was investigated.…”

Nowadays, there is a large variety of dental restorative composite materials on the market, making it difficult to select the proper one. The mechanical properties of various dental materials determine how long they endure when used in the mouth. On the other hand, the therapeutic efficiency of these restorative materials cannot be predicted solely based on their mechanical properties. These features, on the other hand, help with the examination of the impact of changes in their composition. As a consequence, these tests can help the clinician choose the right material. The various mechanical properties can be investigated using a variety of laboratory experiments. The common laboratory tests used to evaluate the mechanical characteristics, composition, and classification of dental composite materials, as well as the factors that influence mechanical qualities, are discussed in this study.

“…Yilmaz used a three-dimensional profilometer to evaluate the mean volume loss and depth of the surface of the specimen after tooth wear to investigate the two-body wear mechanism between teeth and dental materials [ 55 ]. The accurate quantification of the mean total volume of the wear surface is a prerequisite for informing the professional about the wear performance [ 56 ].…”

Dental or tooth wear is a physiological process in the life cycle of teeth. Loss of the occlusal surface may cause excessive tooth wear. Several factors may contribute to tooth wear with different intensities and duration in the oral cavity. The oral cavity is generally compared to a tribological system to determine the various types of wear between teeth and restorative materials and assess the amount of dental wear. However, it is challenging to investigate in vitro and in vivo wear owing to the complexity of tooth wear; thus, a clear correlation between in vitro and in vivo data could not be established. This review is aimed at providing an insight into the etiology of tooth wear and tribological investigations in dentistry.
