Modern dental implants designed for 20 years or more canfail in 5-10 years due to inflammation
The authors of the new work wanted to solve this problem withusing modern smart implants. According to the researchers, their development implements two technologies: the first, a material with nanoparticles that is invulnerable to bacteria, and the second, an integrated light source for phototherapy: it is energized by natural mouth movements, such as chewing or brushing teeth.
The researchers studied the material, barium titanate, which has piezoelectric properties that exploitTo test its potential, the authors used discs of barium titanate nanoparticles and coated them with Streptococcus mutans , the main component of bacterial biofilm, which causestooth decay or, in other words, plaque.
They found that the discs were resistant to plaque build-up, best achieved with samples with higher barium titanate concentrations.
The electrical properties of the material were preserved, and it was not leached during the tests.The material was also mechanically strong, similar to other joints that are used in dentistry.In addition, it did not damage the gum tissue and was safe for the human body.
The authors of the work plan to improve their development so that it can be applied in dentistry.
