Bi-layered single-piece dental implant reduces the need for surgical interventions

Researchers at the International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), an autonomous institute of the Department of Science and Technology (DST), have developed a bi-layered single-piece dental implant combining titanium alloy (Ti6Al4V) and yttria-stabilized zirconia (YSZ). Fabricated using Spark Plasma Sintering (SPS), the implant integrates the load-bearing strength of titanium alloy with the wear-resistant and aesthetic qualities of zirconia. This single-piece structure addresses the limitations of traditional multi-component implants—such as micromovements, corrosion, and the need for multiple surgical procedures—thereby reducing surgical complexity, patient discomfort, and improving long-term stability and biocompatibility.
