Scientists supported by the Ministry of Science and Technology have created a new type of dental implant that combines two materials into a single piece, reducing the number of surgeries needed. The implant was developed at the International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), an autonomous institute under the Department of Science and Technology. This innovation addresses long-standing problems with conventional multi-piece dental implants used across the world.
How the new implant works
Traditional dental implants require three separate components: a fixture screwed into the jawbone, a connecting piece called an abutment, and the crown itself. These multi-part systems typically need two to three surgical procedures and suffer from small movements at the joints between pieces, which can loosen the implant over time.
The new implant merges two materials into one unified structure. Titanium alloy (Ti6Al4V) forms the lower portion that anchors into the jawbone, providing strength and stability. Yttria-stabilized zirconia (YSZ) makes up the upper portion visible in the mouth, offering better appearance and resistance to wear and corrosion. The structure was created using Spark Plasma Sintering, an advanced manufacturing technique that fuses both materials simultaneously despite their different melting temperatures.
Laboratory testing showed the implant achieves a material density of 99.5 percent and displays strong mechanical properties. Hardness measured up to 1350 HV, compressive strength reached approximately 1550 MPa, and flexural strength was approximately 310 MPa. Biological safety tests confirmed the material does not harm human cells, with cell activity exceeding 90 percent in standard tests, and showed negligible damage to red blood cells.
What this means for you
If you need dental implants, this design could mean fewer surgical procedures and faster recovery. The single-piece structure eliminates the weak points where traditional implants fail, potentially offering longer-lasting results. As the technology moves toward commercial production, it may become an affordable option for Indians seeking dental restoration, supporting the country’s goal of developing high-quality medical devices manufactured locally.
