Smart Dental Implants: Feel & Function Like Real Teeth
- Millions of Americans get dental implants each year to address missing teeth.
- Jake Jinkun Chen, professor of periodontology and director of the Division of Oral Biology at Tufts University School of Dental Medicine, led the study.
- the new approach uses a titanium post wrapped in a biodegradable coating containing stem cells and a protein that encourages nerve tissue growth.
Revolutionary smart dental implants are poised to transform the experience of tooth replacement, offering a feel and function that closely mirrors that of real teeth. Researchers are pioneering implants using stem cells and a minimally invasive technique, which is a notable leap forward from conventional methods. This cutting-edge approach features a biodegradable coating packed with stem cells and a nerve-growth stimulating protein,promising to reconnect nerves and provide sensory feedback. Imagine the feeling of natural teeth, restored through advanced dental care. The growth of smart dental implants could improve long-term outcomes. Preliminary tests on rodents showcase promising results, with no signs of rejection. This could revolutionize how patients experience dental procedures, thanks to the integration with the bone.

‘Smart’ Dental Implants Could Mimic Natural Teeth
Updated june 12, 2025
Millions of Americans get dental implants each year to address missing teeth. Now, researchers are developing ”smart” dental implants that promise a more natural feel and function, better replicating real teeth. A study in Scientific Reports details early success using a novel implant and a less invasive surgical approach in rodents.
Jake Jinkun Chen, professor of periodontology and director of the Division of Oral Biology at Tufts University School of Dental Medicine, led the study. He explained that natural teeth connect to the jawbone via soft tissue rich in nerves, providing sensory feedback for chewing and speaking. Traditional implants lack this crucial feedback.
the new approach uses a titanium post wrapped in a biodegradable coating containing stem cells and a protein that encourages nerve tissue growth. As the coating dissolves, it releases thes components, stimulating new nerve tissue formation around the implant. The coating also includes tiny, expandable nanofibers that allow for a minimally invasive procedure, preserving existing nerve endings.
The new smart dental implants and surgical technique could help reconnect nerves,allowing the implant to communicate with the brain like a real tooth,Chen said. He added that this breakthrough could also be applied to other bone implants, such as those used in hip replacements or fracture repair.
In tests with rats, the implants remained secure after six weeks, showing no signs of inflammation or rejection. Imaging suggested the implant integrated through soft tissue rather than direct bone fusion,perhaps restoring nerve function.
This new implant and minimally invasive technique should help reconnect nerves,allowing the implant to ‘talk’ to the brain much like a real tooth.
While these initial results are promising for dental implants, further research, including studies in larger animal models, is needed to assess safety and efficacy before human trials can begin.
What’s next
The research team plans a preclinical study to determine if brain activity confirms that the new nerves surrounding the prototype implant are indeed relaying sensory information, paving the way for advanced dental care.
