Chairside Composite Revolution in Styleitaliano

Modern restorative dentistry is based on the principles of adhesion and minimal invasiveness. In 2011 prefabricated composite resin veneers with high conversion degree were launched in the market simultaneously obtaining two main advantages, they’re user-friendly and they have a good color, shape, and long-term stability. The perfect knowledge of the strengths and techniques of application of these materials is essential for every dentist to get the best results with a correct  working time.

After a fast and very simple clinical evaluation, I decided to use preformed veneers to close the diastema and to solve fractures, enamel wearing and hypersensitivity at the same time, for their simple and predictable use. In order to show her my project before starting, I “glued” a couple of Componeers directly from their box, after a size evaluation, using orthodontic wax.

Bonding protocol is the same as indirect posterior composite restorations, with all the steps of adhesive and 50° C heated composite on the internal side of the veneer. It is compulsory to push the shells with a light and continue pressure ( in order not to have internal air bubbles ), until they fit well, before removing all the composite excess with Styleitaliano Fissura instrument.
