“…Implant‐supported prosthesis has demonstrated a high predictability in the long‐term rehabilitation of both function and aesthetics of partially and fully edentulous patients (Berglundh, Persson, & Klinge, ; Quirynen, De Soete, & van Steenberghe, ).This high predictability is partially due to the establishment of a direct contact between the implant titanium surface and the functional bone (osseointegration) (Cordeiro & Barao, ; Long & Rack, ; Quirynen et al, ). With the aim of improving the dynamics of osseointegration, different modifications in the implant surface micro‐topography increased its predictability and reduced the time to achieve implant stability and clinical success (Albrektsson & Wennerberg, ; Gutwein & Webster, ; Meirelles, Arvidsson, Albrektsson, & Wennerberg, ; Schwartz‐Filho et al, ; Wennerberg et al, ).…”

Objectives:To compare biofilm formation on whole dental titanium implants with different surface micro-topography. Methods:A multispecies in vitro biofilm model consisting of initial (Streptococcus oralis and Actinomyces naeslundii), early (Veillonella parvula), secondary (Fusobacterium nucleatum) and late colonizers (Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans) was grown for 96 hr on sterile titanium dental implants with either minimal (S a : 0.5-1.0 mm) or moderate-roughness titanium surfaces (S a : 1.1-2.0 mm).The resulting biofilms were studied with Confocal Laser Scanning Microscopy (CLSM) and Scanning Electron Microscope. Concentrations (colony-forming units per mL [CFU/ml]) of each bacterium were measured by quantitative Polymerase Chain Reaction (qPCR) and compared by Student t tests.Results: A biofilm, located mainly at the peak and lateral areas of the implant threads, was observed on both implant surfaces, with a greater biomass and a greater live/dead ratio in moderate-compared to minimal-roughness surface implants. Statistically significant higher values of total bacteria (mean difference = 2.61 × 10 7 CFU/ml; 95% confidence interval -CI [1.91 × 10 6 ; 5.02 × 10 7 ]; p = 0.036), F. Nucleatum (mean difference = 4.43 × 10 6 CFU/ml; 95% CI [1.06 × 10 6 ; 7.80 × 10 6 ]; p = 0.013) andA. actinomycetemcomitans (mean difference = 2.55 × 10 7 CFU/ml; 95% CI [1.07 × 10 7 ; 4.04 × 10 7 ]; p = 0.002), were found in the moderate-compared to minimal-roughness surface dental implants.Conclusions: Implants with moderate-roughness surfaces accumulated more bacterial biomass and significant higher number of pathogenic bacteria (F. nucleatum and A. actinomycetemcomitans), when compared to implants with minimal-roughness surfaces, within a similar biofilm structure.

“…New Ti alloys for biomedical applications have been developed with enhanced corrosion and wear resistance, biological properties, and biocompatibility (Revathi et al, 2016). Furthermore, grinding Ti with other metals is a strategy to overcome the mechanical property limitation of Ti material (Cordeiro and Barão, 2017). The main alloying elements are β-Ti alloys using β-stabilizers such as Mo, Zr, Nb, and Ta, which are non-cytotoxic metals (Geetha et al, 2009;Revathi et al, 2016).…”

Oral rehabilitation devices are susceptible to bio-tribocorrosion phenomena in the oral environment due to the synergism of wear, chemical, biochemical, and microbiological processes. This review summarizes the clinical problems and advances obtained based on current scientific evidence as well as the influence of tribological fundamentals, testing methodologies, and protocols in tribocorrosion analyses. The main clinical question related to oral rehabilitation with dental implants is the treatment failure, which is influenced by material degradation. Titanium-based implants are exposed to wear and corrosion challenges in the oral environment since the implantation and along the lifetime service. The titanium (Ti) properties such as structural material, connection design, surface treatments, alloying elements are influencing factors for material behavior. In addition, wear-corrosion factors such as cyclic loads, micromovements, oral biofilm, decontamination methods are also associated with dental implants degradation. These environmental conditions to which dental implants are submitted leads to the release of Ti particles and ions with cytotoxic and harmful effects on peri-implant surrounding tissues. In this context, the current state of the art of bio-tribocorrosion over the last decade has been steadily increasing to understand material degradation. The basic test system used to translate the tribocorrosion phenomena in the oral environment to the bench consists of electrochemical and tribological synergic analysis. The mechanical (applied load, frequency, stroke distance, and number of cycles) and electrochemical (solution composition, concentration of anions, and pH) test conditions are determinants for materials tribocorrosion performance. To overcome the tribocorrosion phenomena some strategies have been used such as alloying elements for Ti-alloys manufacture, surface treatments, and biomolecules immobilization. Further studies need to have the tribocorrosion analyses as the basis for new smart materials development considering the importance of such aspects for the biomaterial clinical behavior. Finally, tribological tests are relevant strategies for understanding the mechanisms of degradation in the oral environment and for providing a way to improve the clinical outcomes of dental implants.

“…Beta Ti has two different crystal forms with respect to temperature change. [25]The α phase has a hexagonal closed-packed (HCP) structure and retain up to 882 °C from room temperature. The β phase has a body centre cubic (BCC) structure when it is above 882 °C [26,27].…”
