Antibacterial coatings on titanium surfaces: a comparison study between in vitro single-species and multispecies biofilm
(ACS applied materials and interfaces, 2015)Dental plaque is a biofilm that causes dental caries, gingivitis, and periodontitis. Most of the studies in antibacterial coatings have been conducted by in vitro single-species biofilm formation, but ... -
Antibacterial properties of hLf1-11 peptide onto titanium surfaces: a comparison study between silanization and surface initiated polymerization
(Biomacromolecules, 2015)Dental implant failure can be associated with infections that develop into peri-implantitis. In order to reduce biofilm formation, several strategies focusing on the use of antimicrobial peptides (AMPs) ... -
Antibacterial properties of triethoxysilylpropyl succinic anhydride silane (TESPSA) on titanium dental implants
(Polymers, 2020)Infections related to dental implants are a common complication that can ultimately lead to implant failure, and thereby carries significant health and economic costs. In order to ward off these infections, ... -
Antifouling coatings for dental implants: PEG-like coatings on titanium by plasma polymerization
(Biointerphases: an open access journal for the biomaterials interface community, 2015-06)Titanium dental implants are commonly used for the replacement of lost teeth, but they present a considerable number of failures due to the infection on surrounding tissues. The aim of this paper is the ... -
Bacteriostatic poly rthylene glycol plasma coatings for orthodontic titanium mini-implants
(Materials, 2022)Titanium mini-implants are used as anchorage for orthodontic tooth movements. However, these implants present problems due to the infection of surrounding tissues. The aim of this work was to obtain a ... -
Biofunctionalization strategies on tantalum-based materials for osseointegrative applications
(Journal of Materials Science: Materials in Medicine, 2015)The use of tantalum as biomaterial for orthopedic applications is gaining considerable attention in the clinical practice because it presents an excellent chemical stability, body fluid resistance, ... -
Chemoselective coatings of GL13K antimicrobial peptides for dental implants
(Pharmaceutics, 2023)Dental implant−associated infection is a clinical challenge which poses a significant healthcare and socio−economic burden. To overcome this issue, developing antimicrobial surfaces, including antimicrobial ... -
Chitosan-recombinamer layer-by-layer coatings for multifunctional implants
(International Journal of Molecular Sciences, 2017)The main clinical problems for dental implants are (1) formation of biofilm around the implant—a condition known as peri-implantitis and (2) inadequate bone formation around the implant—lack of ... -
Citric acid passivation of titanium dental implants for minimizing bacterial colonization impact
(Coatings, 2021)Surface topography and physical-chemical properties usually play a key-role in both osseointegration improvement and bacterial colonization reduction over the surface of dental implants. The aim of this ... -
Comparison of the superelasticity of different nickel–titanium orthodontic archwires and the loss of their properties by heat treatment
