“…This finding may be influenced by the hardness, microstructure, and supply method of the ceramic materials. This assumption was partially supported by previous studies [ 1 , 21 , 49 ]. In general, the wear of tooth enamel is influenced not only by the roughness and hardness of the material but also by the material surface microstructure and friction environment.…”

“…Moreover, in clinical studies, enamel wear by zirconia-based materials is larger than or comparable to tooth–tooth contact [ 9 , 19 , 20 ]. Thus, these conflicting results were due to the obtained values of either or both vertical loss and volumetric loss of enamel wear by zirconia-based materials using different methods among the studies [ 20 , 21 ]. Furthermore, although the wear behavior of opposite zirconia-based materials has been reported in some cases [ 22 , 23 ], most of them are unclear because enamel wear has been the focus of previous studies [ 20 ].…”

Wear Behavior between Aesthetic Restorative Materials and Bovine Tooth Enamel

et al. 2022

Tooth enamel wear occurs because of daily mastication and occlusion. This study investigated the wear behavior of bovine teeth against aesthetic restorative materials in vitro. Abrader specimens were fabricated using four tooth-colored restorative materials (zirconia, lithium disilicate glass ceramic, dental porcelain, and resin composite), with bovine tooth enamel as a control. Flattened bovine tooth enamel was used as the substrate specimen. These materials were characterized by Vickers hardness tests and surface roughness measurements. Two-body wear tests between the abrader and substrate specimens were performed, and the worn topographies were evaluated using a contour-measuring instrument and 3D laser microscope. The restorative materials and bovine tooth enamel had similar surface roughness but different hardness and wear behaviors. Bovine teeth showed the largest wear in tooth–tooth contact as the abrader and substrate specimens. Compared to bovine teeth, zirconia, lithium disilicate glass ceramic, and dental porcelain showed greater hardness and less wear on their surfaces, and less substrate wear of the opposite tooth enamel. The lowest hardness resin composite showed intermediate wear on its surface, resulting in the lowest substrate wear. Accordingly, dentists should pay attention to the selection of restorative materials to reconstruct their morphologies owing to different wear behaviors.

“…However, when performing a comparison of means in a meta-analysis, a decrease was found in the wear produced at the points or contact surfaces that were initially related to the antagonist, as stated by [ 21 ]. The comparison of glazed or polished contact surfaces was a variable analyzed in several studies, especially those that used zirconia, obtaining results of less wear when it is polished [ 13 , 14 , 15 , 17 , 21 , 40 ], unlike the higher values when it is glazed [ 16 , 19 , 20 ], and what was mentioned before has been verified in the reviews carried out by [ 34 ].…”

Background: This systematic review and meta-analysis aimed to evaluate the wear of the antagonist tooth in ceramic restorations. Material and methods: This study was carried out based on Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) recommendations; it was also registered in PROSPERO (register number: CRD42022316252). Three databases were consulted in the literature search, Embase, Scopus, and Web of Science. The citation searching was conducted by two researchers independently. The clinical studies that evaluated wear in antagonist teeth concerning ceramic restoration were included. Twelve articles were selected after eliminating duplicates ones and applying the inclusion criteria, and two were chosen through citation. Fourteen articles were considered for the qualitative and quantitative analysis (meta-regression and meta-analysis). Results: The mean linear wear of the antagonist tooth in relation to feldspathic was 8.914 μm, for lithium disilicate it was 0.018 μm, and for zirconia it was 0.257 μm. The mean volumetric wear of the antagonist tooth in relation to feldspathic was 0.273 mm3, for hybrid ceramic it was 0.030 mm3, for lithium disilicate it was 0.018 mm3, and for zirconia it was 0.014 mm3. The mean natural tooth wear was 0.7974 μm per month. Tooth wear caused by zirconia at six months was 31.755 μm, at 12 months it was 24.648 μm, and at 24 months it was 20.662 μm. Conclusions: Feldspathic produces greater wear of the antagonist tooth from ceramic restorations linearly and volumetrically. In addition, zirconia generates the least wear that will decrease over time, and it will be equal to or less than the natural wear in the tooth.

“…[144][145][146] A recent systematic review has indicated that polishing can reduce the wear of zirconia restorations on natural teeth more than glazed or porcelain veneered restorations. 147 Furthermore, the glaze layer can deteriorate with time in function, resulting in zirconia exposure to the harsh oral environment. 148 Another study has compared the antagonist wear for both zirconia and LDS systems, with zirconia samples experiencing less wear and LDS equivalent wear relative to natural enamel.…”

“…Wear is a complex process affected by many factors, such as material properties, surface characteristics, oral environment, and function 144–146 .

Objective: The background and clinical understanding of the properties of currently available indirect restorative systems and fabrication methods is, along with manufacturer and evidence-based literature, an important starting point to guide the clinical selection of materials for tooth and/or implant supported reconstructions. Therefore, this review explores most indirect restorative systems available in the market, especially all-ceramic, along with aspects of manufacturing process, clinical survival rates, and esthetic outcomes. Overview: Progressive incorporation of new technologies in the dental field and advancements in materials science have enabled the development/improvement of indirect restorative systems and treatment concepts in oral rehabilitation, resulting in reliable and predictable workflows and successful esthetic and functional outcomes. Indirect restorative systems have evolved from metal ceramics and polymers to glass ceramics, polycrystalline ceramics, and resin-matrix ceramics, aiming to improve not only biological and mechanical properties, but especially the optical properties and esthetic quality of the reconstructions, in attempt to mimic natural teeth. Conclusions: Based on several clinical research, materials, and patient-related parameters, a decision tree for the selection of indirect restorative materials was suggested to guide clinicians in the rehabilitation process. Clinical Significance: The pace of materials development is faster than that of clinical research aimed to support their use. Since no single material provides an ideal solution to every case, professionals must continuously seek information from well designed, long-term clinical trials in order to incorporate or not new materials and technological advancements.
