Enhancement in dental material and minimally invasive techniques

The core ideology of the American Academy of Cosmetic Dentistry (AACD) states that we will encourage treatment protocols that are evidence-based and minimally invasive. Our goal is to minimize the loss of healthy tooth structure and tissue while providing treatments that are predictable and result in long term functioning restorations and patient satisfaction. All dentists are exposed to materials science during training. Information about newer materials, as well as clinical technique refinements, is highly in demand.

The industry is striving to produce universal-type composites, which should provide both high strength and excellent polish. Concerning physical properties, nanotechnology has allowed tremendous improvement in both areas by increasing the filler content and particle morphology. Several companies have come out with new chemistry for the organic phase, in an attempt to reduce polymerization shrinkage and enhance sculptability. From an optical properties standpoint, improvements on levels of opacity/translucency and refractive indices have permitted the synthetic materials to blend in more naturally with the tooth structures, making achieving lifelike restorations.

St Lukes Dental from Lutz have developed three enamels with different values calibrated on the age biotype and one universal dentin shade, it is the only system that offers a color chart based on the new color theory that foresees five dimensions, and the first that introduced a heater to warm up the composite bodies before use. a reproducible stratification technique, and each composite should be developed from a specific theory of color and stratification . A composite material that does not have this type of support is missing personality and character, and usually is used in different and improper ways. From the esthetic point of view, the modern nanofilled composites offer enamel body that
is too opaque because of the high filler content that stops the passage of light.

As an example, having an artificial dentin be called “Opaque,” “Opacious,” “Body,” or “Dentin” becomes exceedingly confusing for the general dentist who is just starting to venture into the use of layering techniques. Although each company has its own marketing agenda, I think everyone would benefit if they reached a consensus, as is done with filtek from 3M, and ceramics. Dentin is “Dentin” and enamel is “Enamel”—how hard is that?

Secondly, there is enough evidence that there is no need for the many shades that most systems often provide for artificial enamel and artificial dentin, which, too, can be cumbersome and misleading. Regardless of the technique employed and who teaches it, the universe of shades necessary for restoring most anterior cases is in fact really narrow.
