Abstract
Composite restorations have been widely used in daily practice due to comprehensive indications in anterior teeth related to the immediate solution of an aesthetic problem. Compared to other options, composite restorations are well-indicated in clinical situations due to their conservative approach, reversibility, and repair ability, especially in younger patients. It is mandatory to recognize these specific clinical situations.
Among several techniques described in the literature, the layering technique is commonly claimed to reproduce the aspects of natural dentition and to allow control effects of translucency and right opacity, resulting in superior overcome. However, the layering technique involves deep acquaintance with adhesive procedures, material handling, and dental anatomy, making it complex and time-consuming.
To overcome such drawbacks, simplification of the regular technique with fewer composites as a cosmetic solution, as well as the use of the injectable technique with flowable consistency composites, use of composite milled blocks (CAD-CAM), as recently 3D printed resins, have been increased in restorative dentistry.
This lecture will discuss the indications of composites nowadays and the actual techniques for composite layering (dentin/chromatic/achromatic enamel), the modified technique using fewer shades, injectable techniques, and indirect composite veneers. The step-by-step sequence of each technique is described, along with the challenges and essentials of each one. Results obtained by research done at NYU will also be presented.
Video demonstration of clinical cases done in patients will be performed to describe the technical steps.
