Summary
Dental implant surfaces attract microbes, leading to biofilm formation and peri-implantitis, a major cause of implant failure. Surface modifications are explored to combat microbial accumulation and prevent infections.
Area of Science:
- Biomaterials Science
- Microbiology
- Periodontology
Background:
- Titanium (Ti) dental implants are a successful treatment for edentulism but are prone to microbial adhesion.
- Biofilm formation on implant surfaces causes peri-implant mucositis and peri-implantitis, leading to implant failure.
Purpose of the Study:
- To review current evidence on dental implant biofilm accumulation and pathogenesis of implant-related infections.
- To discuss surface modifications for anti-biofilm properties to control peri-implantitis.
Main Methods:
- Critical review of existing literature on dental implant biofilms.
- Analysis of factors contributing to microbial accumulation and pathogenicity.
- Evaluation of surface modification strategies for anti-biofilm properties.
Main Results:
- Biofilm formation is driven by factors like matrix production, carbohydrate availability, and cross-kingdom interactions.
- Implant topography and biofilm characteristics (organization, resistance) hinder microbial control.
- No consensus exists on optimal protocols for microbial control and peri-implant disease treatment.
Conclusions:
- Understanding biofilm pathogenesis is crucial for developing effective peri-implantitis treatments.
- Surface modifications offer promising strategies to reduce microbial load and prevent implant-related infections.

35.6K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...
