The dental implant is a surgically inserted metal rod or screw. It is implanted inside the jawbone of a patient. Thus, not only does the implant replace the crown of a tooth, it also replaces the dental root. Once in place, the dental implant connects with the jawbone through a process called osseointegration. This fusion takes place over the course of about 2 to 4 months. However, once it is complete, it allows the implant to be just as stable as a natural tooth would be.
