At 4 months after placement, what percentage of mineralization is expected at the implant-bone interface?

At four months following the placement of an implant, it is generally understood that approximately 60% mineralization occurs at the implant-bone interface. This figure reflects the biological processes of osseointegration, where bone cells proliferate and begin to lay down new mineralized bone matrix around the implant surface.

During the initial healing phase, the integration of the implant with the surrounding bone is critical. Over the first few months, osteoconductive properties of the implant surface encourage bone deposition, leading to gradual increases in mineralization. By the four-month mark, many studies highlight that substantial mineralization occurs, making it a critical period for evaluating the success of the implant’s integration into the jawbone.

The other options do not accurately reflect the expected level of mineralization at this time point. While initial healing may result in lower percentages, and further mineralization continues beyond four months, 60% stands as the benchmark for this particular stage in the healing process.
