“…In our study, Katana Avencia, a composite block was analyzed. This study analyzed marginal fit, nevertheless, it has to be reminded that mechanical properties shall be always considered, being CCBs affected by monomer compositions, especially if specific types of monomers are contained (e.g., TEGDMA) [ 56 , 57 , 58 , 59 ].…”

(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 test samples were commercially produced from Ti, Zr, and Ta sections with about 99% purity in sheet form. These test samples were previously tested in chewing tests in a different study [20]. Within the scope of this study, Bruxism chewing tests were performed in an area outside the wear area.…”

Bruxism can be defined as the process of direct contact with teeth and dental materials with an involuntary jaw-tightening movement. In this process, teeth and dental materials can be exposed to various damage mechanisms. This study aims to analyze the wear behavior of cp-Ti, Ti-5Zr, and Ti-5Ta alloys, which are frequently preferred as dental materials in the human body, under different Bruxism wear processes by experimental in vitro chewing cycle and finite element analysis simulation method. Cp-Ti and titanium alloy test specimens with cylindrical geometry were exposed to a direct every-contact wear mechanism for 30 seconds under 100N bruxism chewing bite force. The bruxism chewing cycle continued for 300 minutes at a frequency of 1.8 Hz. Microanalysis of the wear surfaces of the samples after the experimental study was carried out with Scanning Electron Microscopy(SEM). The Bruxism wear volume loss that occurred in the wear area of the test specimens was measured with a 3D non-contact profilometer. The results obtained within the scope of this study showed that the Bruxism wear resistance increased by adding zirconium and tantalum to pure titanium material. In axial Bruxism bite forces, the least wear volume loss occurred at 90° bite forces chewing process. However, in the Finite Element Analysis simulation, it was observed that the maximum stress area was evident in the implant structure at 75° bite force chewing process. This will make it difficult for the implant to osseointegration within the body and will cause various damage mechanisms to the integrity of the implant.

“…In three body wear, there is presence of an external agent between two body participating in the abrasion. In resin chemistry, structure of ingredient bisphenol A-glycidyl methacrylate (Bis-GMA) and triethylene glycol dimethacrylate (TEGDMA) plays significant role in the mechanical and wear performance of dental composite [62][63][64]. Since complete polymerization (100%) i.e.…”

In the present study, comparative analysis of glass ionomer and nanofillers in the performance of dental composite has been reviewed. In dental composite, a number of particulate fillers specifically nanoparticle are being tested and used. A new approach has been tried and investigated to replace expensive nanofillers with the other filler such as glass ionomer. There is a strong need to understand the scientific method, to conduct the clinical trial, and to perform the laboratory test to evaluate role of each parameter, constituent in the performance of dental composite. The present research reviewed the recent finding, possible opportunity and challenges for use of glass ionomer as replacement of nanofiller in dental composite. The existing literature on the favorable and non‐favorable side of glass ionomer is critically evaluated. The major aspect considered in the present review was to evaluate the surface roughness, mechanical properties and wear properties. The present article attempted to provide a state‐ of‐ the‐art analysis of fabrication method, surface treatment method and comparative analysis on role of particulate filler versus glass ionomer on the performance based on mechanical and wear testing mechanism.
