This message from Redbud Dental of Edmond OK looks at one of the miracles of modern dentistry: the dental restoration.
Let’s pretend you are a biomedical engineer working in the field of dentistry before the introduction of dental restorations. The men and women of your generation who have missing or damaged teeth want to repair or replace them with a man-made substitute.
You have been hired to find or create a material that can be used to create fillings, crowns, and dental bridges. It must be bondable to living tooth structure as well as other materials necessary for specific appliances.
This new material must also be biocompatible with oral soft tissues, tooth enamel, dentin, and bone. It can’t create allergic reactions in the wearers and must be corrosion-resistant to the chemicals in saliva, foods, and beverages.
It must resist infection regardless of ever-present bacteria in the mouth. And it can’t contain toxic chemicals that could be absorbed into the bloodstream. Tall order, right?
Well, now we know that such a thing exists because restorative dentistry has been around for a long time. Nowadays, there are numerous materials used alone or in combination, including porcelain, ceramic, and metals such as gold and silver amalgam. Though the metals are extremely strong and malleable, they don’t meet some patient’s esthetic requirements and are used mainly for back teeth.
