A dental implant is a root form piece of mostly titanium that is placed in the jawbone to anchor either a single tooth or multiple teeth to it. A dental implant used to be in different shapes and forms, but for decades now, the screw form of the dental implant has proven to be most reliable. Although 99.9% of the dental implants in the world are made up of titanium alloys, there is a small percentage of implants that are made up of zirconium. Zirconium dental implants are more expensive to buy, take longer to integrate, and are harder to restore – hence their limited usage.
