“…In another work, Bottino et al encapsulated doxycycline in a nanotube-modified dentin adhesive [ 133 ], in order to propose a procedure for the synthesis of therapeutic adhesives. Similar studies were performed with other materials commonly used in dentistry, such as resins, composites and alloys [ 134 , 135 , 136 , 137 ]. Thus, both graphene and carbon nanotubes are able to increase the mechanical strength of alloys, resins, polymers and cements in dentistry.…”

Nanomaterials are commonly considered as those materials in which the shape and molecular composition at a nanometer scale can be controlled. Subsequently, they present extraordinary properties that are being useful for the development of new and improved applications in many fields, including medicine. In dentistry, several research efforts are being conducted, especially during the last decade, for the improvement of the properties of materials used in dentistry. The objective of the present article is to offer the audience a complete and comprehensive review of the main applications that have been developed in dentistry, by the use of these materials, during the last two decades. It was shown how these materials are improving the treatments in mainly all the important areas of dentistry, such as endodontics, periodontics, implants, tissue engineering and restorative dentistry. The scope of the present review is, subsequently, to revise the main applications regarding nano-shaped materials in dentistry, including nanorods, nanofibers, nanotubes, nanospheres/nanoparticles, and zeolites and other orders porous materials. The results of the bibliographic analysis show that the most explored nanomaterials in dentistry are graphene and carbon nanotubes, and their derivatives. A detailed analysis and a comparative study of their applications show that, although they are quite similar, graphene-based materials seem to be more promising for most of the applications of interest in dentistry. The bibliographic study also demonstrated the potential of zeolite-based materials, although the low number of studies on their applications shows that they have not been totally explored, as well as other porous nanomaterials that have found important applications in medicine, such as metal organic frameworks, have not been explored. Subsequently, it is expected that the research effort will concentrate on graphene and zeolite-based materials in the coming years. Thus, the present review paper presents a detailed bibliographic study, with more than 200 references, in order to briefly describe the main achievements that have been described in dentistry using nanomaterials, compare and analyze them in a critical way, with the aim of predicting the future challenges.

“…The goal of this manuscript is to illustrate the merits of Ti50Zr in oral cavities as functions of surface treatment. Based on the existing expertise, we chose to present the unmodified and modified surface properties of Ti50Zr [36][37][38] with better biocompatible antibacterial coatings. Drug loading and release from such coatings [39][40][41][42] are discussed as a part of the coated Ti50Zr performance, and future trends in dental materials applications are presented.…”

“…Then, TiO 2 -ZrO 2 nanotubes with different diameters (20-70 nm) were produced in two-step anodization procedures, applying different potentials in a range from 15 to 45V on Ti50Zr [78]. Two-step anodization procedures form nanotube coatings containing crystalline phases, both before and after annealing [38]. All nanotubular samples provided better cell viability than the base metal.…”

Despite many discussions about Ti versus Zr, Ti remains the golden standard for dental implants. With the extended use of implants, their rejection in peri-implantitis due to material properties is going to be an important part of oral health problems. Extended use of implants leading to a statistical increase in implant rejection associated with peri-implantitis raises concerns in selecting better implant materials. In this context, starting in the last decade, investigation and use of TiZr alloys as alternatives for Ti in oral dentistry became increasingly more viable. Based on existing new results for Ti16Zr (Roxolid) implants and Ti50Zr alloy behaviour in oral environments, this paper presents the trends of research concerning the electrochemical stability, mechanical, and biological properties of this alloy with treated and untreated surfaces. The surface treatments were mostly performed by anodizing the alloy in various conditions as a non-sophisticated and cheap procedure, leading to nanostructures such as nanopores and nanotubes. The drug loading and release from nanostructured Ti50Zr as an important perspective in oral implant applications is discussed and promoted as well.

“…After annealing, a change in the crystal system occurs, passing from hexagonal to orthorhombic, causing changes in the mechanical properties as well. The conversion of the crystalline phase leads to a decrease in hardness due to the increased volume and d spacing parameters of the new structure, which could be possibly translated into a decrease in material density [19]. Reference [22] showed that the annealing temperature and the conversion of crystalline phases of the As indicated by the topography images through the scratch imprint widths, the un-coated TiZr sample revealed the highest mean hardness (H) parameter value of 6.20 ± 1.12 GPa.…”

“…With such properties, TiZr alloys are the most promising biomaterials to be used in 3D printing of medical devices by using modern additive manufacturing technologies, and more knowledge will benefit applications. According to previous studies [ 18 , 19 ], it was revealed that the nanomechanical properties as well as the biocompatibility of the Ti50%Zr binary alloy can be affected by the condition of annealing treatments (in air, reduced in Ar/H2) that are followed after the anodizing procedure.…”

In this work we present the results of a functional properties assessment via Atomic Force Microscopy (AFM)-based surface morphology, surface roughness, nano-scratch tests and adhesion force maps of TiZr-based nanotubular structures. The nanostructures have been electrochemically prepared in a glycerin + 15 vol.% H2O + 0.2 M NH4F electrolyte. The AFM topography images confirmed the successful preparation of the nanotubular coatings. The Root Mean Square (RMS) and average (Ra) roughness parameters increased after anodizing, while the mean adhesion force value decreased. The prepared nanocoatings exhibited a smaller mean scratch hardness value compared to the un-coated TiZr. However, the mean hardness (H) values of the coatings highlight their potential in having reliable mechanical resistances, which along with the significant increase of the surface roughness parameters, which could help in improving the osseointegration, and also with the important decrease of the mean adhesion force, which could lead to a reduction in bacterial adhesion, are providing the nanostructures with a great potential to be used as a better alternative for Ti implants in dentistry.
