Five Most Common Errors in Posterior Composites

Direct composite restoration is a very common procedure used in daily practice by dentists. Filling posterior cavities using resin composites has always been a challenging task for dentists looking for a fast and reliable technique. Field isolation and bleeding control, the achievement of an tight contact point, the management of deep cavities and post-operative sensitivity are the most common errors encountered during posterior restorations.

Besides the choice of a preforming resin-based material, and an adhesive system, the technique of using those products are of paramount importance.

The choice of the restoration is made according to different criteria: type and position of the tooth, remaining tooth structure, patient habits and hygiene, etc….. The aim of this presentation, using well documented clinical cases, is to offer to the dentist a precise analysis of the 5 most relevant clinical elements, in order to achieve a successful posterior restoration.
