Technically, the implant itself refers only to the titanium screw. This screw is secured into the jaw, acting as an artificial tooth root. This provides the support for the abutment and crown that form the rest of the prosthetic tooth. A dental implant, if taken care of properly, is expected to last upwards of forty years. A dental implant costs between $3500 and $4900 depending on the need for bone grafting or other procedures.
