Today’s Reno Dentist blog post looks at one of the miracles of modern dentistry: restorative dentistry.
Let’s pretend you are a biomedical engineer working in the field of dentistry before the inception 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 that substitute to make fillings, crowns, and dental bridges.
Consider the physical and chemical requirements of this incredible item. It must sustain forces of 162 pounds per square inch, hundreds of times a day, day after day, year after year. It must be resistant to cracking and chipping. Moreover it must not damage the enamel on opposing teeth. This material must also maintain its size and shape and be resistant to shrinking.
It must be bondable to living tooth structure as well as other materials necessary for specific appliances. It must be compatible with the soft tissues in the mouth as well as tooth enamel, dentin, and bone. It can’t generate allergic reactions in the wearers. It must be corrosion-resistant to 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.
And we haven’t even mentioned the aesthetic properties. Ideally, this incredible material would look identical to genuine teeth in color, opacity, and translucence.
Of course, we know that such a substance exists because dental restorations have been around for a long time. Currently, there are numerous materials used alone or in combination including porcelain, ceramic, and metals such as gold and silver amalgam. Though the metals are immensely strong and malleable, they don’t meet some patient’s aesthetic requirements and are used mainly for back teeth.
