Dental implants have been used to replace missing teeth since the mid-1960s, but in recent years their use has become much more widespread. They can be used to support crowns replacing single missing teeth, bridges that restore a larger span of missing teeth, or even dentures.
Implants are manufactured from titanium, a metal that is known to be compatible with body tissues and able to bond with adjacent bone during healing. There is a now a wealth of evidence from studies and from clinical experience to show that dental implants are a safe and convenient way to replace lost teeth with natural-looking results.
Titanium and Zirconia—Pros and Cons
Both materials can integrate with bone with equal success provided certain protocols are followed. We do, however, have a much longer history with titanium. Some of my patients have titanium that is still functioning after 20-35 years. We may find the same success with zirconia, but until the material has been tested for the same amount of time as titanium, we simply will not know.
Titanium implants are much more versatile than zirconia because they can be made as one piece or two-piece systems. In two-piece systems, the implant replaces the root and is generally placed at the level of the underlying bone. Attached to this is a post or abutment—the part that sticks through the gums and is used to support or attach the teeth.
