You've probably heard about dental implants — today's best option for replacing missing teeth; maybe you even have one or more already. A dental implant is a tiny screw-shaped metal post that sits in your jawbone and supports a lifelike dental crown. Natural teeth and implant-supported teeth have differences and similarities.
The main difference between implants and natural teeth — besides the fact that you were born with one and not the other — is the way they attach to your bone. Implants actually fuse to the bone, becoming part of it. This is a unique property of titanium, the metal from which implants are made. Maintaining that attachment is extremely important; we will discuss how best to ensure that in a moment.
Natural teeth do not ever become part of the bone that surrounds them. Instead, they attach to it via the periodontal ligament (“peri” – around; “odont” – tooth), which is made up of tiny fibers that go into the tooth on one side and the bone on the other. These fibers form a sort of hammock for each tooth.
Another difference is that natural teeth can decay while implant-supported teeth can't. But that doesn't mean you don't have to worry about dental hygiene — far from it! And here's where we get to the main similarity: oral hygiene is extremely important to maintain both teeth and implants. Lax oral hygiene for either can result in bacterial infections that may lead to gum disease, and even bone loss.
The main enemy of a properly fused implant is a bacterial infection known as “peri-implantitis” (“peri” – around; implant “itis” – inflammation), which starts when bacterial biofilm (plaque) is allowed to build up on implant-supported crowns. Peri-implantitis can lead to a well-like or dish-shaped loss of bone around the implant, which in turn can cause the implant to lose its attachment to the bone. If this happens, the implant can no longer function. Fortunately, this infection is preventable with good brushing and flossing techniques at home, and regular professional cleanings here at the dental office.
So another similarity, then, is that natural teeth and implants can last a lifetime with proper care. And that's the result we're aiming for!
