Dental implants are available in a variety of materials. Traditionally, implants were made from titanium. This biocompatible material has been used in treatment for broken bones for years, and it makes a great implant post option for most patients. For those who have allergies or sensitivities to traditional dental metals, zirconia implants have proved to be effective alternatives. Additionally, these lighter-colored implant posts are less likely to be visible through the gum tissue over time.
