“…Traditional Ti-based materials such as pure Ti and Ti–6Al–4V alloy have been widely applied as dental materials. − However, their poor resistance to physical abrasion and fatigue fracture require enhancement. − Metal carbide or nitride coatings (such as TiC, TiN, TiON, and TiAlN) are used to strengthen the surface hardness and wear resistance; however, the bonding strength of the interface poses a new challenge. − Ti n+1 AX n phases, which are MAX phases, exhibit good tribological properties, damage tolerance, and oxidation and corrosion resistance because of their unique structure, in which alternate near-close-packed layers of covalent M 6 X octahedrons are interleafed with metal-like A atom layers. − Their flexural strength and fracture toughness (Ti 3 AlC 2 , 340–450 MPa, 4.6–9.1 MPa·m 1/2 ; Ti 3 SiC 2 , 720 MPa, 4.5–16 MPa·m 1/2 ; Ti 2 AlN, 350–371 MPa, 8.2 MPa·m 1/2 ) are much greater than those of common bioceramics (such as hydroxyapatite, 65–85 MPa, 0.65–0.70 MPa·m 1/2 ). Thus, these machinable ceramics have been used as concrete dry drills, gas burner nozzles, and heat exchangers. , …”

Herein, the cytocompatibility of selected MAX phases, Ti3AlC2, Ti3SiC2, and Ti2AlN, were systematically evaluated using in vitro tests for the first time. These phases were anoxic to preosteoblasts and fibroblasts. Compared with the strong viable fibroblasts, the different cellular responses of these materials were clearly distinguishable for the preosteoblasts. Under an osteoblastic environment, Ti2AlN exhibited better cell proliferation and differentiation performance than Ti3AlC2 and Ti3SiC2. Moreover, the performance was superior to that of a commercial Ti–6Al–4V alloy and comparable to that of pure Ti. A possible mechanism was suggested based on the different surface oxidation products, which were determined from the binding energy of adsorbed Ca2+ ions using first-principles calculations. Compared with the partially oxidized TiC x O y layer on Ti3AlC2 and Ti3SiC2, the partially oxidized TiN x O y layer on the Ti2AlN had a stronger affinity to the Ca2+ ions, which indicated the good cytocompatibility of Ti2AlN.

“…However, less attention has been given to how the manufacturing methods of abutment screws and the complexities of internal threading modi cations affect the stability of dental implants. While previous studies [30][31][32][33][34] have explored surface coatings and their mechanical effects on screw loosening, this research seeks to understand the direct impact of manufacturing methodsmachining, thread rolling, and die methods-on the likelihood of screw loosening.…”

This study investigated the effect of three abutment screw manufacturing methods and modifications in the internal threading process of dental implants on screw loosening. A total of 30 screws were produced, with 10 screws for each manufacturing method. Additionally, 30 dental implants were fabricated and categorized based on their internal threading technique: 15 implants used a cutting tap, referred to as cutting implants (C), and 15 implants used a forming tap, referred to as formed implants (F). Each group of the screws was divided into 2 subsets: one subset was paired with C implants, and the other was paired with F implants. Subsequently, torque loss for each screw was measured before and after a vibration test using a digital torque meter, and a one-way ANOVA and an independent samples t-test (α = 0.05) were used to investigate the significance level of the difference in screw loosening between manufacturing methods. The study found that machined, thread-rolled, and die screws exhibited an average total torque loss of 3.51%, 5.13%, and 7.52% when paired with C implants, and 2.42%, 4.33%, and 6.27% when paired with F implants, respectively. Statistically, the one-way ANOVA and the independent samples t-test revealed a significant effect of the abutment screw type on the total torque loss (P < .05). Moreover, the implant type had a significant effect on the torque loss values before and after the vibration test (P < .05). These findings suggest that screw manufacturing method and internal threading modifications are critical factors in enhancing the mechanical stability of implant components.

Abrasion often happened in abutment screw during the operation of dental implant, and it often resulted in reduction of tightness between the abutment and the implant, which always caused the connection failure at last. The purpose of this in vitro study was to research the wear resistance of implant abutment screw under different surface treatment methods, and to find appropriate method to increase the wear resistance of implant abutment screw. Titanium abutments which were treated by low-temperature surface nitriding and low-temperature magnetron sputtering with TiN coating respectively were the experimental groups, and the untreated titanium implants and related abutments were used as the control groups. Wear resistance was obviously increased after low-temperature surface nitriding and low-temperature magnetron sputtering.
