Layering Technique of Resin Composite Method for Direct Anterior Teeth Restorations: A New Appraisal

Abstract

Introduction: Composite resins can be effectively recycled to progress the patient's esthetics concluded minimally invasive, low cost and high clinical presentation managements. The layering techniques of composite resins in different thicknesses, with varying grades of opacity and translucency, permit to create esthetic restorations with dental structures physical appearance. Aim: The intention of the training was to appraise the characteristics, values and approaches of stratification of resins composite materials and to demonstrate these approaches with clinical cases. Materials and method: An electronic search of scientific articles referring to the stratification of composite materials was done using a single medical database. The attention on the choice of keywords as well as the presence and elimination criteria were the directorial elements of the research. All articles were included after the title, the abstract and finally, the full text was checked. Only relevant research has been reviewed. Based on the results, several methods of stratifications have been used in clinical practice. Results and discussion: The concept of natural stratification, anatomical stratification, the stratification of the anterior teeth using a dentine hue and a predefined thickness of enamel, or a single layer of material and the correct placement of pigments and opacities, lead to the achievement of esthetic and predictable direct restorations of nanocomposite resins. Conclusions: Within the limit of this study, it is concluded that, to achieve aesthetic excellence, dentists should understand and apply artistic and scientific principles when layering materials, respecting the optical properties of natural dental structures.
