Abstract

Peri-implantitis is one of the most common complications after dental implant placement. Researchers have demonstrated that the peri-implantitis tends to occur around dental implants with a rough surface rather than those with a smooth surface. We aimed to investigate the ability of a smooth titanium (Ti) surface containing strontium (Sr) to enhance bone formation as a result of strontium’s capacity to support osteoblast proliferation and differentiation. A thin titanium oxide film was formed on an as-mirror polished Ti surface by dipping in 5% sodium hypochlorite (NaOCl) solution for 24 h, followed by thermal treatment at 350°C. The Ti surface was then treated with 1% strontium nitrate (Sr(NO₃)₂) solution and turned in spin coater. The surface morphology, chemical composition, and release of strontium ions (Sr²⁺) were evaluated. The results demonstrate that strontium in the form of Sr²⁺ was successfully doped into the titanium dioxide (TiO₂) film by this simple chemical treatment.
