Absolute isolation is without a doubt a basic and advised operation for bonding procedures especially in indirect adhesive restorations, especially when it comes to multiple restorations. This way is possible to guarantee the best conditions of adhesion in order for restorations to last in time.
The origin of the absolute isolation dates back to the year 1864 when the american dentist Standford Barmun had difficulties in patients with much salivary flow. Then he decided to cut a piece of rubber and make a perforation to pass the tooth by and fix it with a clamp.
Many years have passed since the first isolation, and many things have changed as well, form the materials to the techniques. In this case the author presents a technical solution with orthodontic separating elastomers.
I want to thank Jordi Manauta for being a great motivation in this beautiful profession, and to the CEDgroup Team (Andres Roman, Nicolas Caviglia, Santiago Romero, Gisela González, Juliana Durando and Elvio Durando) as “none of us” knows more than all together.
