Minimally invasive preparations: Contact lenses

Conservative aesthetic dental treatment methods have been increasingly requested in clinical practice, especially when the anterior region presents aesthetics problems, such pigmentations, malpositioning, and problems of proportion and size of the teeth. Thus, this work aims to conduct a brief literature review on esthetic restorations with minimally invasive preparations and describe step by step, by reporting a case, the clinical protocol to be followed by the professional for making dental contact lenses. Currently, what is more conservative in aesthetic treatments are ceramic fragments, usually made of lithium disilicate ceramics, which are 0.2-0.5 mm thick and, therefore, require minimal tooth preparation. Such treatment was selected for a male patient aged 17-year-old who was admitted in the Aracatuba Dental School, Universidade Estadual Paulista, complaining of unsatisfactory aesthetics due to dental problems of size and proportion. The achieved result was very satisfactory for both the patient and professional. We conclude that the contact lenses are currently the best treatment option for elective aesthetic cases, once it is an extremely conservative rehabilitation that faithfully mimics the dental structure and shape, besides being a very predictable treatment.
