Implant interface design has significant impact on implant microbial leakage
Although state-of-the-art implant manufacturing techniques are implemented using modern technology, challenges related to 2-piece implants still remain.
A recent study published in the International Journal of Dentistry suggested that the implant interface design has a significant impact on implant microbial leakage and that implants with a line-contact interface exhibited higher resistance to leakage than those with partial face-contact
Although state-of-the-art implant manufacturing techniques are implemented using modern technology, challenges related to 2-piece implants still remain. The formation of micro defects on the surfaces of an implant and abutment components during milling and manufacturing processes results in "micro gaps" at the implant-abutment interface (IAI). These micro gaps could be a reservoir for bacterial accumulation, peri‑implant bone loss, and peri‑implantitis.
