ARCI Develops Bi-Layered Single-Piece Dental Implant

In September 2026, scientists at International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI) developed a single-piece dental implant combining titanium alloy and zirconia for improved stability and biocompatibility.

Key Points

Bi-Layered Design: The implant integrates Ti6Al4V titanium alloy with yttria-stabilised zirconia into one structure.
Titanium Region: Ti6Al4V forms the load-bearing fixture and supports jawbone integration.
Zirconia Region: YSZ forms the crown region, providing wear resistance and improved aesthetics.
Problem Addressed: Single-piece integration can reduce micromovements associated with conventional multi-component implants.
Surgical Advantage: The design could reduce multiple surgical procedures and associated patient discomfort.
Manufacturing Technology: Spark Plasma Sintering enables simultaneous densification of titanium alloy and zirconia.
Material Density: The fabricated structure achieved 99.5% density with no major defects.
Interface Strength: Testing showed a well-bonded interface without cracks, pores or delamination.
