HANNOVER, Germany: Researchers in Germany are developing customised dental implants designed to match each patient’s individual jaw structure. The approach combines computer modelling with advanced 3D printing to create implants that distribute masticatory forces more effectively. Scientists believe that the technology could improve long-term stability and reduce the risk of implant failure.

To address some of the reasons for implant failure, researchers at Hannover Medical School and its engineering partners in the interdisciplinary research unit FOR 5250 are developing new implant designs. FOR 5250 involves seven institutions in Germany and brings together experts from medicine, engineering and materials science. In late 2025, the German Research Foundation extended funding for the unit by four years, providing €4.4 million to continue the research.

Unlike the designs of off-the-shelf implants, the new designs are created using computer simulations that model the mechanical stresses generated during chewing. By analysing these forces before manufacturing, the researchers can optimise the implant’s internal architecture to reduce stress concentrations in the surrounding bone and improve long-term stability.

The implants are produced using 3D printing, which allows highly detailed structures to be built layer by layer according to digital specifications. This approach enables the production of implants whose internal structure varies in different regions, allowing them to be adapted to variations in bone density and mechanical load within the jaw.

Surface design is also an important focus of the project. After printing, the implants are treated with mechanical and chemical processes such as sand-blasting and etching to promote the attachment of osteoblasts. Researchers are also developing magnesium-based coatings that may enhance osseointegration while simultaneously inhibiting bacterial colonisation and biofilm formation.

The team is now exploring how the technology could benefit patients with reduced bone density, including many older adults. Although further research is required before clinical use, the researchers hope that the personalised approach will eventually enable safer and longer-lasting dental implant therapy.
