Researchers at Fraunhofer have developed a 3D printed adhesive, harnessing the properties of dihydroxyphenylalanine (DOPA), to enhance the lifespan of medical implants like hip prostheses. The adhesive, impressed by the mussel’s pure bonding capability, combines DOPA with apatite, a ceramic present in bones and tooth.
This improvement addresses a crucial challenge in hip substitute surgical procedures: the physique’s tendency to reject titanium implants. By facilitating a stronger bond between bone and titanium, this method may considerably scale back the necessity for a number of surgical procedures, significantly in youthful sufferers.
The idea of utilizing DOPA for adhesion is just not new, however its utility in 3D printing, particularly for creating customized shapes that match particular person anatomical wants, marks a considerable development. Conventional titanium castings are restricted in dimension and form, however 3D printing permits for exact customization, which is essential for matching complicated geometries discovered within the human physique. This know-how can adapt to varied situations, similar to reconstructing bones shattered in accidents, thereby rising the contact space and guaranteeing a safer and long-lasting match for hip replacements.
The potential of this undertaking extends past hip implants. It aligns with ongoing analysis in fields like Bioglass, which give attention to treating dental ailments and selling bone development round implants. With additional analysis and regulatory approvals, this adhesive may considerably improve the standard of life for people with joint points attributable to age or harm.
