Ceramic implants offer better aesthetics than traditional metal implants. Metal implants are silver or metal in color. Typically, the crown that sits on top of the implant hides the metal coloring. However, if gums are thin and translucent, the silver color may show through, usually near the gum line. Recent studies demonstrate that gum cells have a better affinity for ceramic implants than metal implants. We often see firm pink gum surrounding ceramic implants and the healing response is typically faster than titanium implants. Ceramic implants are shaped to mimic the roots of teeth and are often better at preventing “black triangles or food catches” between crowns and implants.
METAL SENSITIVITY AND ALLERGIES
Both ceramic and titanium implants are biocompatible and will safely integrate with bone and tissue in the body. However, a very small percentage of patients are particularly sensitive or allergic to metals. Since zirconia implants are hypoallergenic, they may be a great alternative for those with metal sensitivities. Though uncommon, metal allergies and sensitivity can develop over time. Zirconia implants will not cause this type of allergy. Many patients also choose ceramic implants as a biological, “metal free alternative” solution for their missing teeth.
SINGLE PIECE DESIGN
All types of ceramic implants have been developed to resist fracture and osseointegrate (bond to the bone). Advances in ceramic implant design have allowed manufactures such as Zeramex® and Nobelbiocare® to create a two-piece design that contains no metal components. Straumann® also produces a two-piece implant that contains a metal abutment screw which is not in contact with the tissue. Ceraroot® is a one stage implant that has the abutment “built in” which ultimately provides support for the crown. Most clinicians would agree that a one stage implant has no micro gap and no micromovements thereby providing the best possible foundation for a new crown. A two-piece ceramic implant allows for greater customization in crown design due to variations in bone and tissue anatomy.
