Abstract
Titanium implants are commonly used in the field of dentistry for prosthetics such as crowns, bridges, and dentures. For successful therapy, an implant must bind to the surrounding bone in a process known as osseointegration. The objective for this ongoing study is to determine the potential of different implant surface coatings in providing the formation of hydroxyapatite (HA). The coatings include titanium nitride (TiN), silicon dioxide (SiO2), and quaternized titanium nitride (QTiN). The controls were a sodium hydroxide treated group, which functioned as a positive control, and an uncoated titanium group. Each coated disc was submerged in simulated body fluid (SBF), replenished every 48 h, over a period of 28 days. Each coating successfully developed a layer of HA, which was calculated through mass comparisons and observed using scanning electron microscopy (SEM) and energy dispersive analysis x-rays (EDX). Among these coatings, the quaternized titanium nitride coating seemed to have a better yield of HA. Further studies to expand the data concerning this experiment are underway.
Highlights
Dental implants in a variety of forms have appeared as early as 2500BC among the ancientEgyptians, with the introduction of titanium implants emerging in the 1970s [1]
The objective of this study is to investigate the HA formation ability of different thin film coatings in vivo through immersion in simulated body fluid in vitro as a function of the quantity of HA that forms on these coatings, which have anti-corrosive and anti-bacterial properties [23,24,25,26]
As seen in implants treated with NaOH, HA was formed in simulated body fluid to facilitate titanium bonding to bone by forming sodium titanate on the implant surface [34]
Summary
Dental implants in a variety of forms have appeared as early as 2500BC among the ancientEgyptians, with the introduction of titanium implants emerging in the 1970s [1]. Dental implants in a variety of forms have appeared as early as 2500BC among the ancient. Most dental implants are made of titanium or titanium alloys (Ti6Al4V) because of this metal’s mechanical strength, low density, corrosion resistance and high biocompatibility [2,3,4,5]. Osseointegration is the binding of bone to the implant site through a complex matrix of osteogenic cells, platelets, and blood clots [6]. This may be due to titanium’s hydrophilic exterior, surface grooves, or chemical nature that induces bone fusion with the implant, making restoration more stable and longer lasting [7].
