Essential Lines: a simplified filling and modeling technique for direct posterior composite restorations.

There is a continuing increase in demand for the direct restoration of posterior teeth with resin-based composites. However, the execution of these restorations, especially the reproduction of the anatomical details of the tooth, still presents difficulties for most clinicians. Nowadays, resin-based composite restorations have become increasingly popular due to the development of new materials and filling techniques.

Natural, polarized light and the choice of composite: a key to success in shade matching of direct anterior restorations- Part II.

With time, natural and polarized light proved their importance and utility in dental photography. After studying the physical properties of natural and polarized light, in the first part of this article, to understand their correlation with dental materials and natural teeth and how to use them in the best combination, this second part will illustrate the importance of a polarized image in color matching, how to manipulate it and how to apply it in clinical cases.

Natural, polarized light and the choice of composite: a key to success in shade matching of direct anterior restorations- Part I.

The biggest challenge while restoring anterior teeth is shade matching. Hue, chroma, value, opacity, translucency, intensity and anatomy must be seen to be reproduced. To see we need light, knowing that there is a strong relation between the nature of light and the components of natural teeth.

The Simultaneous Modeling Technique: closing gaps in posteriors.

Direct posterior restorations represent a widespread procedure in daily practice. Occlusal layering is often considered a complex task, generally not predictable and often requiring several occlusal adjustments. Moreover, direct posterior restorations are time consuming, as many small increments must be applied and cured individually to control shrinkage stress.

Stratification in anterior teeth using one dentine shade and a predefined thickness of enamel: a new concept in composite layering--Part II.

While restoring an anterior tooth, shade matching is one of the crucial points that we can face to have an esthetic final outcome. After studying the physical and optical characteristics of enamel and dentine in the first part of this article, the second part will propose a new method for color matching and a clinical stratification using a simple and reproducible procedure for anterior restorations with only one dentine and one enamel shade.

Stratification in anterior teeth using one dentine shade and a predefined thickness of enamel: a new concept in composite layering--Part I.

Restoring an anterior tooth has always been a challenge, regarding the shade matching, the choice of colors, opacities, translucencies of our composites and the final anatomical outcome. This article proposes a new method for color matching and a clinical stratification using a simple and reproducible procedure for anterior restorations. The physical and optical characteristics of enamel and dentine will be studied and applied to our dental materials that we are using to restore anterior teeth.

Composite shade guides and color matching.

Finding reliable systems that can help the clinician match the color of direct composite restorations is often an issue. After reviewing several composite shade guides available on the market and outlining their main characteristics and limits (unrealistic specimen thickness, not made with the same material the clinician will use, only a few allow to overlap enamel tabs on dentin ones), the authors evaluated the reliability of a system designed to produce self-made standardized "tooth-shaped" shade guide specimens. Small changes in composite enamel thickness may determine huge differences in esthetic outcomes.

Esthetic direct restorations in endodontically treated anterior teeth.

Composite resins are the most commonly used materials in restorative dentistry. When first introduced in dental practice, they began to change the esthetic approach to anterior teeth treatments. At first they simply represented a 'white' alternative to unesthetic materials.

Achieving a precise color chart with common computer software for excellence in anterior composite restorations.

Achieving similar features to those on natural teeth is a common problem with esthetic restorations. Color matching is a fundamental procedure required to perform a predictable composite resin restoration. It is no longer enough to measure these criteria with conventional shade guides, which provide the hue and chroma, but do not take into account other dimensions of the tooth such as value, intensives, opalescence and characterizations.
