Osseointegrated dental implants play an important role in restorative dentistry. However, plaque accumulation may cause inflammatory reactions around the implants, sometimes leading to implant failure. In this in vivo study the influence of two physical hard coatings on bacterial adhesion was examined in comparison with a pure titanium surface. Thin glass sheets coated with titanium nitride (TiN), zirconium nitride (ZrN) or pure titanium were mounted on removable intraoral splints in two adults…

Modified implant surfaces show different biofilm compositions under in vivo conditions.
TLDR
A coating of glass surfaces with zirconium nitride significantly reduced the species richness in early bacterial colonization but the diversity was not significantly changed and a ZrN coating appears to rather modify the quantity of early bacterial adherence than the quality of the microbial community structure.
Influence of the Periodontal Status on the Initial-Biofilm Formation on Titanium Surfaces.
TLDR
The results obtained in this study shows that the composition and the proportion of the species that initially colonize Ti surfaces are highly influenced by the periodontal status more than the surface characteristics of the Ti implant.
Microbial community composition on modified dental implant surfaces: an in vivo study.
TLDR
This preliminary study showed that a ZrN-Ti disk surface harbors a significantly different microbial composition from a polished Ti surface, which might help to influence the adhesion of bacteria that are less pathogenic, thereby reducing the risk of peri-implantitis.
The Relationship between Biofilm and Physical-Chemical Properties of Implant Abutment Materials for Successful Dental Implants
TLDR
In the case of partially edentulous patients affected by periodontal disease, the ideal type of implant abutments utilized should be one that adheres the least or negligible amounts of periodontopathogenic bacteria.

Oral bacterial adhesion on amorphous carbon and titanium films: effect of surface roughness and culture media.
TLDR
A-C and Ti films were deposited on rough and smooth surfaces and cultured with different microorganisms belonging to the oral microbiota with mycoplasma medium (MM) or human saliva, showing an increased number of CFU's on rough surfaces, especially on the a-C surfaces.
Surface Characterization and Assessment of Biofilm Formation on Two Titanium-Based Implant Coating Materials
Implant-related oral diseases such as peri-implantitis and peri-mucositis are largely initiated by bacterial colonization on artificial implant surfaces. Therefore, implant and abutment material…
Biocompatibility and antibacterial properties of zirconium nitride coating on titanium abutments: An in vitro study
TLDR
An in vitro study to compare the biocompatibility and antibacterial activity of four different surfaces: uncoated Ti6Al4V, anodized, and coated with titanium nitride or zirconium nitride, finding a substantial similarity between the surfaces and their compatibility with clinical applications.
In vivo and in vitro biofilm formation on two different titanium implant surfaces.
TLDR
Initial bacterial adhesion to differently textured titanium surfaces is primarily influenced by R(a), whereas the influence of SFE seems to be of only minor importance, and the micro-structured parts of an implant that are exposed to the oral cavity should be highly polished to prevent plaque accumulation.

TLDR
Physical modification of titanium implant surfaces such as coating with TiN or ZrN may reduce bacterial adherence and hence improve clinical results.

TLDR
ATP-bioluminescence technology was demonstrated to be a suitable system to evaluate bacterial colonization in the oral cavity and its role in the development of perimplantar infections.
An in vivo Study of the Influence of the Surface Roughness of Implants on the Microbiology of Supra- and Subgingival Plaque
TLDR
In nine patients with fixed prostheses supported by endosseous titanium implants, 2 titanium abutments (trans-mucosal part of the implant) were replaced by either an unused standard abutment or a roughened titanium abUTment, justifying the search for optimal surface smoothness for all intra-oral and intra-sulcular hard surfaces for reduction of bacterial colonization and of periodontal pathogens.
In vivo early human dental plaque formation on different supporting substances. A scanning electron microscopic and bacteriological study.
TLDR
The amount of early deposits on different substances seems to be related to the degree of their surface roughness, while plaque formation was qualitatively similar.
The influence of abutment surface roughness on plaque accumulation and peri-implant mucositis.
TLDR
The present results confirm the findings of a previous short-term study, indicating that a further reduction of the surface roughness, below a certain "threshold R(a)" (0.2 microns), has no major impact on the supra- and subgingival microbial composition.
Bacterial adhesion on titanium nitride-coated and uncoated implants: an in vivo human study.
TLDR
TiN surfaces showed a significant reduction of the presence of bacteria, and this fact could probably be important in the decrease of the inflammation of the peri-implant soft tissues.
Oral bacterial attachment to titanium surfaces: a scanning electron microscopy study.
TLDR
Ti implant surface characteristics appeared to influence oral bacterial attachment in vitro and the in vitro attachment system has proven its usefulness for future bacterial attachment studies with model implant surfaces.
The influence of titanium abutment surface roughness on plaque accumulation and gingivitis: short-term observations.
TLDR
Clinical evaluation seems to indicate that a certain surface roughness is necessary for increased resistance to clinical probing, and the results indicate the existence of a threshold roughness below which no further impact on the bacterial adhesion and/or colonization should be expected.

TLDR
Early plaque formation on solid surfaces is influenced predominantly by the oral environment rather than by material-dependent parameters, and may be ascribed to the presence of the pellicle layer, which apparently masks any difference among materials, with regard to surface properties and biocompatibility.
The occurrence of periodontitis-related microorganisms in relation to titanium implants.
TLDR
The peri-implant space was examined for the presence of periodontitis-related microorganisms and the bacteriological composition of submucosal plaque samples was investigated using non-selective media and selective media for Actinobacillus actimomycetemcomitans, Porphyromonas gingivalis, and Prevotella intermedia.
