Recipes for aesthetic composite restorations

Abstract

Composite restorations have been widely indicated in daily practice due to replacing traditional amalgam-based materials and improving the esthetic outcome of polymer-based materials. In clinical situations, composite restorations are better indicated than other options due to their conservative approach, reversibility, and ability to repair, 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 allow control of stress generated by polymerization shrinkage. However, the layering technique involves deep acquaintance of adhesive procedures, material handling, and dental anatomy, making it complex and time-consuming. 

In order to overcome such drawbacks, advances in polymer chemistry engineering and new layering techniques have been proposed. For instance, low shrinkage composites have been developed for bulk filling of cavities, eliminating the steps required in traditional layering techniques, which substantially simplifies composite resin restoration procedures. Bulk filling allows the restoration to be built in either one or two layers, according to the type and features of the bulk-fill composite. 

Learning Objectives

  • Discuss indications of composites nowadays.
  • Discuss the essential techniques for composite layering (dentin/chromatic/achromatic enamel) and the modified technique using fewer layers and the low shrinkage composites. 
  • Discuss the step-by-step sequence of each technique is described, along with the challenges and essentials of each one. Results obtained by research done in NYU will also be presented.
