Dental implants are nowadays a standard treatment to replace missing teeth and restore function aesthetics. However, biological complications associated with implants, e.g., peri-implant infections, common jeopardize the success of treatment. The main aim this thesis was explore strontium (Sr) as possible prevention strategy against since Sr has been shown have antibacterial action also promote titanium (Ti) implant osseointegration.

Abstract Peri-implantitis is a bacterial infection that causes soft tissue inflammatory lesions and alveolar bone resorption, ultimately resulting in implant failure. Dental implants for clinical use barely have antibacterial properties, colonization biofilm formation on the dental are major of peri-implantitis. Treatment strategies such as mechanical debridement antibiotic therapy been used to remove plaque. However, it particularly important prevent occurrence peri-implantitis rather than treatment. Therefore, current research spot has focused improving properties implants, construction specific micro-nano surface texture, introduction diverse functional coatings, or application materials with intrinsic properties. The aforementioned surfaces can be incorporated bioactive molecules, metallic nanoparticles, other components further enhance osteogenic accelerate healing process. In this review, we summarize recent developments biomaterial science modification applied inhibit facilitate bone-implant integration. Furthermore, summarized obstacles existing process laboratory reach clinic products, propose corresponding directions future perspectives, so provide insights into rational design aim balance efficacy, biological safety, property.

Eradicating biofouling from implant surfaces is essential in treating peri-implant infections, as it directly addresses the microbial source for infection and inflammation around dental implants. This controlled laboratory study examines effectiveness of four commercially available debridement solutions '(EDTA (Prefgel®), NaOCl (Perisolv®), H2O2 (Sigma-Aldrich) Chlorhexidine (GUM® Paroex®))' removing acquired pellicle, preventing pellicle re-formation a multi-species oral biofilm growing on titanium surface, compare results with effect novel formulation peroxide-activated 'Poloxamer gel (Nubone® Clean)'. Evaluation removal was conducted using scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy photoelectron to assess surface morphology, elemental composition chemical composition. Hydrophilicity assessed through contact angle measurements. The model included Streptococcus oralis, Fusobacterium nucleatum Aggregatibacter actinomycetemcomitans, reflecting natural microbiome's complexity. Biofilm biomass quantified safranin staining, viability evaluated confocal laser microscopy, SEM used morphological analyses biofilm. Results indicated that while no single agent completely eradicated biofilm, gel' activated 'H2O2' exhibited promising results. It minimized re-contamination by significantly lowering angle, indicating enhanced hydrophilicity. combination also showed notable reduction carbon contaminants, suggesting effective organic residues addition effectively reducing viable bacterial counts.

Soft tissue adhesion and sealing around dental maxillofacial implants, related prosthetic components, crowns are a clinical imperative to prevent adverse outcomes of periodontitis periimplantitis. Zirconia is often used fabricate implant components crowns. Here, we hypothesized that UV treatment zirconia would induce unique behaviors in fibroblasts favor the establishment soft seal. Human oral were cultured on specimens confluency before placing second specimen (either untreated or treated with one minute 172 nm vacuum (VUV) light) next first separated by gap 150 µm. After seven days culture, only transmigrated onto VUV-treated zirconia, forming 2.36 mm volume zone 5.30 leading edge. Cells migrating enlarged, robust formation multidirectional cytoplastic projections, even day seven. Fibroblasts also horizontally placed 45° 60° tilted specimens, latter configurations compromising initial attachment proliferation. However, VUV mitigated negative impact tilting, higher tilt angles increasing difference cellular behavior between control specimens. Fibroblast size, perimeter, diameter greater than exclusively zirconia. reduced surface elemental carbon induced superhydrophilicity, confirming removal hydrocarbon pellicle. Similar effects observed glazed silica surfaces. One-minute photofunctionalization therefore promotes human fibroblast proliferation, especially under challenging culture conditions, induces specimen-to-specimen transmigration sustainable for at least days.
