In-vitro experiments on bio-functional calcium phosphate based coatings on titanium dental implant

Abstract

Dental implants are a revolution in dentistry, but there are still certain deficiencies that need to be addressed. The objective of this paper was to investigate the dissolution capabilities and film properties of Calcium Phosphate (CaP) based layers on a Titanium (Ti-6Al-4V) alloy surface produced with the radiofrequency magnetron sputtering method. These coatings have demonstrated good osseointegration capability due to their similarity to bone mineral matter. The bioactive coating materials are chosen as Calcium Phosphate, Zinc chloride, and Silver nitrate. Microstructural investigations of coated components were assessed using FTIR Spectroscopy, Scanning Electron Microscopy, Energy Dispersive analysis, and Atomic Force Microscopy. Bacterial adhesion to biomaterials is still a major issue when it comes to medical equipment. Antimicrobial peptides have generated interest due to the rise in antibiotic-resistant bacteria. The fact that there are concerns regarding the development of antibiotic resistance as a result of the development of traditional antibiotics to prevent illness reflects the complexity of the matter. Antimicrobial activity was found in the calcium phosphate coated specimens against gram-positive Staphylococcus epidermidis and Staphylococcus aureus bacteria. The antimicrobial evaluation showed that discs made with bioactive coating inhibited bacterial growth and biofilm formation.
