“…Indeed, it presents finescale surface porosity which results in micro-structural improvement and better corrosion performance compared to CrN alone [36]. From a dentistry point of view, to the author's knowledge, no data is currently available on its usage for dental application and the only available data on medical implants are from orthopedic implants application [28][29][30]. Following the manufacturer's description, the physical properties of the coating applied on the abutment are: coating thickness 2-6 µm; coating hardness: 2500 ± 200 HV; Roughness Ra: 0.08-0.10 µm; friction coefficient: 0.3-0.4.…”

“…Recently a novel chromium nitride/ niobium nitride (CrN/NbN) coating, defined as ''super-latex'' coating [23], which is obtained during the manufacturing process through the deposit of 1200 alternated layers of CrN and NbN (Figure 1), was made available for dentistry application (CE N°1935/2004). Currently, the only available data from the literature is from orthopedic implant applications [28][29][30]. To the authors knowledge, no data is currently available on its application for dental implant purposes.…”

Background: The aim of the present multi-center split-mouth randomized control trial was to investigate the effect on peri-implant tissue of abutment with chromium nitride/ niobium nitride (CrN/NbN) coatings (super-latex) compared to traditional machined surface. Methods: Two adjacent posterior implants were inserted in 20 patients. A machined abutment was randomly screwed on either the mesial or distal implant, while a super-latex abutment was screwed on the other one. Implant survival rate, peri-implant probing depth (PPD), plaque index (PI), and bleeding index (BI) were collected 6 months after surgery, while marginal bone loss (MBL) was evaluated at T0 and T6.; Results: Implant survival rate was 97.7%. A total MBL of 0.77 ± 0.50 mm was recorded for super-latex abutments, while a mean MBL of 0.79 ± 0.40 mm was recorded for the abutment with machined surface. A mean PPD of 1.3 ± 0.23 mm was recorded for the super-latex Group, and a mean PPD of 1.31 ± 0.3 was recorded for the machined surface Group. PI was of 0.55 ± 0.51 for super-latex Group and 0.57 ± 0.50 for machined Group, while BI was of 0.47 ± 0.49 for super-latex Group and of 0.46 ± 0.40 for the machined one. No statistically significant difference was highlighted between the two Groups (p > 0.05). Conclusions: After a 6-month observational period, no statistically significant differences were highlighted between super-latex abutment and traditional machined abutment. Further in vitro studies as well as clinical research with longer follow-ups are required to better investigate the surface properties of the novel abutments’ super-latex coating and its effect on the oral tissues.

“…For example, the addition of carbon fibers to PEEK can alter the mechanical properties of PEEK to approximate the elastic modulus of human bone [ 31 , 32 ]. Wear particles generated on the articular surface can cause macrophages to engulf debris particles, trigger the release of inflammatory cytokines, and stimulate osteoclast bone resorption, which can lead to prosthesis loosening [ 33 , 34 ]. Therefore, changing the mechanical properties of PEEK and reducing wear particles are the main focus.…”

“…Recently, in addition to TiAlN, ternary metal nitride coatings such as TiNbN and TiZrN have been synthesized and possess good mechanical properties than the binary ones [ 7 , 8 ]. By adding Nb into TiAlN, TiAlNbN coatings also have good mechanical and tribological properties and can be used as implant components due to their biocompatibilities [ 9 , 10 , 11 ]. M. Mikula et al [ 10 ] showed that adding Nb into the TiAlN coatings promoted texture evolution toward the (200) phase, and alloying TiAlN with NbN decreased elastic stiffness while the hardness maintained similar.…”

In tribological applications, the degradation of alloy nitride coatings is an issue of increasing concern. The drawbacks of monolayer hard coatings can be overcome using a multilayer coating system. In this study, single-layer TiAlNbN and multilayer TiAlNbN/AlCrN coatings with AlCrN layer addition into TiAlNbN were prepared by cathodic arc evaporation (CAE). The multilayer TiAlNbN/AlCrN showed B1 NaCl structure, and the columnar structure continued from the bottom interlayer of CrN to the top multilayers without interruption. After AlCrN addition, the TiAlNbN/AlCrN coating consisted of TiAlNbN and AlCrN multilayers with a periodic thickness of 13.2 nm. The layer thicknesses of the TiAlNbN and AlCrN were 7 nm and 6.2 nm, respectively. The template growth of the TiAlNbN and AlCrN sublayers stabilized the cubic phases. The introduction of bottom CrN and the TiAlNbN/CrN transition layers possessed com-position-gradient that improved the adhesion strength of the coatings. The hardness of the deposited TiAlNbN was 30.2 ± 1.3 GPa. The TiAlNbN/AlCrN had higher hardness of 31.7 ± 3.5 GPa and improved tribological performance (wear rate = 8.2 ± 0.6 × 10−7 mm3/Nm) than those of TiAlNbN, which were because the multilayer architecture with AlCrN addition effectively resisted abrasion wear.
