How to ensure functionality, aesthetics and durability of posterior composite restorations?

Date: 13 October 2023

Time: 14:00-15:00 CET

Making posterior composite restorations can often be demanding, if a lot of tooth structure has been lost, in preparations that are located near or below the gingival margin. Often in these cases, when the margin of the preparation is already in the dentin, we think about which material is best to use. In cases lack of a marginal ridge, it is necessary to create a technically precise area of the contact point, which requires a good choice of the matrix system, its placement and isolation of the working field. The durability of the composite restoration also depends on the stability of the adhesive bond, i.e. the prevention of microleakage between the edges of the filling and the tooth. Furthermore, a poorly placed adhesive system (drying of dentin, incomplete polymerization, moisture) can cause the formation of nanoleakage as the most common reason for postoperative hypersensitivity in patients, but also faster breakdown of the adhesive bond. The lecture will explain the sensitive stages of making a composite filling in the back region that can be the reason for failure (loss of adhesive bond, marginal discoloration, poor contact point...). The specifics of the latest universal adhesion systems will be described through a clinical protocol. Their advantages, limitations, clinical work, application possibilities in restorative dental medicine and post-endodontic tooth care will be explained. A number of clinical cases will be presented and how to avoid the most common mistakes in clinical work.
