A composite filling is considered a "direct" filling because it can be applied in a single visit directly by our dentist in our dental clinic. Inlays, onlays and overlays are considered "indirect" fillings because, like crowns, they are made in a laboratory. This means that a patient will need at least two visits: one visit to clean the cavity and take an impression, and a second visit to bond the inlay/onlay/overlay.
The choice between direct or indirect filling is made by our dentist. In general, if the destruction is greater than 40%, our dentist will opt for the indirect method.
In addition, ceramic restoration still has its advantages, particularly in terms of durability and strength.
