For years, Corvette bodies were made of fiberglass, the lightweight yet strong material made from extremely fine glass fibers. So you might imagine that if it’s strong enough for a sports car, fiberglass would be an excellent option for smile restoration-and you’d be right. However, the posts used to bond crowns to roots are typically made of metal.
A team of Spanish biomechanics and ergonomics experts have been working on a project that proves fiberglass should be used more than metal during smile restoration procedures. Through various tests, they have found that fiberglass supports a greater load than steel, doesn’t require precise measurements, and helps prevent injury to the root if the tooth becomes fractured.
In addition to strength benefits, fiberglass also has notable cosmetic benefits. When metal is used, there’s a risk of the new tooth eventually looking dark because of its transparent material. With fiberglass, teeth can remain looking whiter.
Word of the project’s results has spread in the dental community, and dentists are anticipating the opportunity to use what will likely be a patented design that multiple manufacturers will compete over and patients will benefit from.
