“…That can be compared to the effect of commercial lubricant agents [12]. However, there are few studies on the biotribocorrosion in simulated oral environments containing glycoproteins, such as mucin and albumin both present in saliva [3,12,13,15,43,44].…”

“…Therefore, corrosive substances can accumulate in the internal connection of dental implant systems and also in the biofilms formed on external and inner surfaces of the prosthetic gaps [25,26]. The pH lowering associated to corrosive substances and under mechanical solicitations can decrease the long-term performance of dental implant systems [6,13,16]. In addition, polished surfaces can become rough in the oral cavity due to the effect of food debris or due to the friction between contacting surfaces increasing biofilm accumulation [9,12,13].…”

“…Along time, several areas in the oral cavity can be covered by a complex microbial community embedded in an extracellular matrix composed of polysaccharides, proteins, nucleic acids, and water, known as oral biofilm [58][59][60]. As a result, the pH in the oral cavity is frequently altered reaching low values after the intake of acidic substances and/or acids release from oral microbial metabolism [13,39,50]. Moreover, the biofilm composition is influenced by the local pH values, considering the release and tolerance of bacteria to acids [39,41,50,61].…”

“…Nowadays, the tribocorrosion behavior of materials has been studied in biological environments originating the new designation of bio-tribocorrosion [3,[12][13][14][15]. Even though it is not possible to simulate the complex oral environment for biotribocorrosion tests, in vitro studies can, at least, determine the influence of each component on bio-tribocorrosion behavior of biomaterials.…”

The oral cavity is a complex environment where corrosive substances from dietary, human saliva, and oral biofilms may accumulate in retentive areas of dental implant systems and prostheses promoting corrosion at their surfaces. Additionally, during mastication, micromovements may occur between prosthetic joints causing a relative motion between contacting surfaces, leading to wear. Both processes (wear and corrosion) result in a biotribocorrosion system once that occurs in contact with biological tissues and fluids. This review paper is focused on the aspects related to the corrosion and wear behavior of titanium-based structures in the oral environment. Furthermore, the clinical relevance of the oral environment is focused on the harmful effect that acidic substances and biofilms, formed in human saliva, may have on titanium surfaces. In fact, a progressive degradation of titanium by wear and corrosion (tribocorrosion) mechanisms can take place affecting the performance of titanium-based implant and prostheses. Also, the formation of wear debris and metallic ions due to the tribocorrosion phenomena can become toxic for human tissues. This review gathers knowledge from areas like materials sciences, microbiology, and dentistry contributing to a better understanding of bio-tribocorrosion processes in the oral environment.

Society is aging fast. The percentage of people aged above 65 years is forecast to rise from 12.4% (in 2000) to 23% by 2100. [1] The figures for 2030 for Europe and the United States are %20% and 30% respectively. [2] At present, almost 23% of US citizens over 65 are completely edentulous, creating great demand for dental replacements. [3] According to the compound annual growth rate (CAGR) forecast, the global dental market is expected to exceed $8 billion by the end of 2024, up from $4.46 billion in 2016. [1] Moreover, with rising life expectancy, modern implants have to serve much longer without requiring revision surgery. This is challenging, especially in the case of elderly people, who tend to suffer diseases that increase the risk of implant rejection. [2] Thus, advanced healthcare requires constant development in the design and fabrication of dental materials. Currently, commercially pure titanium (CP-Ti) is a leading metallic material in the global dental replacements market. [4] This is mainly due to its biocompatibility and high resistance to corrosion in body fluids. Those properties are governed by the presence of a passive layer on Ti surface, created by its strong tendency to oxidize. [5] Nanostructuring by large plastic deformation techniques is a promising approach to altering Ti properties that are essential for dental applications. [1,[6][7][8][9][10] While clinical trials have confirmed the successful application of dental implants fabricated from nanocrystalline Ti, [4,9] works are still ongoing to develop strategies aimed at enhancing biological response and antibacterial properties without impacting mechanical properties. [11][12][13][14] In this Review, we describe recent approaches taken to modify the properties of nanocrystalline Ti for biomedical applications. Our study focuses on the following aspects: (i) improving biomedical nano Ti properties through bulk and surface modifications, and (ii) the effect of microstructural changes induced by processing of nano Ti on the results of modifications. This analysis is prefaced by a brief description of the effect of nanostructure on Ti mechanical and functional properties.
