A few years ago, the introduction of ceramic facets brought to the universe of Restorative Dentistry, the possibility of improving the aesthetic appearance of smiles while minimizing dental aging and wear. At this time, dental “contact lenses” dominate cosmetic dentistry, and often appear in the media, in the “perfect smiles” of various artists.
Today, it is possible to construct ultra-thin dental ceramic structures (dental contact lenses), only 0.2 mm in thickness. In this way, the wear on teeth, traditionally reduced by the use of ceramic facets, has now become almost extinct with application of contact lenses in simple and highly aesthetic and minimally invasive treatments.
Contact lenses are indicated in cosmetic treatment for minor corrections such as imperfections of the dental shape (closure of spaces, lengthening, width, etc.), anterior teeth with small fractures or with diastema, and to disguise dental and small spots discolorations.
Contact lenses are made in a laboratory environment, from a model generated by the dentist in his or her office. They have long-term durability, between 5 and 10 years, depending on the case and patient care, which should include avoiding destructive habits, such as biting pens or bottle caps, hard corn-kernel popcorn, etc. When necessary, the patient can either reframe them or simply remove them in a dental office normally without any complications.
As in the case of natural teeth, excessive force while biting or chewing, bruxism, biting on hard substances of any kind can fracture teeth and also damage dental contact lenses. It is up to the dentist to analyze the patient’s bite and make the necessary scrubs so that this does not happen. It is also worth remembering that both patient cooperation and correct oral hygiene care extend the useful life of any dental treatment, aesthetic or not.
