Maybe the shade is close but not quite right. Maybe the restoration holds initially, but marginal breakdown or debonding occur. Or maybe the incisal embrasures are closed, making the veneers look unnatural. When this happens, clinicians can often question materials, but many find the answer is not a better composite or a stronger whitening treatment, but the sequence itself and the respect paid to each step. Whitening, bonding, and composite restoration are typically treated as three separate decisions. They're taught separately, billed separately, and in most CE environments, presented separately. Typically, but not always.   **Whitening as a Restorative Decision** "Whitening has traditionally been seen in literature as a stand-alone procedure, in isolation of its possible impact on other procedures in the dental practice," says Dr. Renato Miotto Palo, a Brazilian-trained dentist and member of Ultradent's Clinical Advisory team, specializing in endodontics and teeth whitening. He says viewing teeth whitening as an integral step within cosmetic dentistry presents an excellent opportunity to achieve better and more lasting results. "Reactive oxygen species \[byproducts of the whitening process that can temporarily inhibit adhesive bonding\] could be one of the issues for additional bonding. Or, if my whitening process isn't adequate, I can get shade relapse that will interfere in the final restoration in the future." The framing of whitening as something that interacts with the procedures that follow is central to how Dr. Palo approaches the procedure. The clinical stakes are higher than that framing suggests. "Patients are different," Dr. Palo explains. "We have different substrates, different dentins, different proteins, and different structures that bring us different shades. So how can we deal with this heterogeneity of the population and be able to choose the best material for that case?" The answer matters not just for the whitening outcome, but for everything built on top of it, including the bond. "Bleaching wreaks havoc on bonding," says Dr. Shea Bess, who lectures nationally on adhesion. "We need 10 days of no bleach to achieve optimal bond strengths."   **What a Bright Substrate Gives the Restorative Dentist** When Dr. Newton Fahl looks at a composite veneer case, the first thing he's thinking about is what's underneath. One of the most decorated clinicians in cosmetic dentistry, Dr. Fahl says achieving truly natural-looking restorations starts well before the composite is placed. "If I want to have an optimal result shade-wise, I need to have a tooth substrate that is lighter instead of me trying to block it out with a more opaque composite material, which would render the final restoration not as lifelike," he says. "What Dr. Palo does through bleaching is to elevate the light reflectance, the value, allowing me to use very thin layers of composites to cosmetically change the setup, with more translucent enamel composite layers. That in turn will render my restorations more natural looking because of light transmission." Whitening is a foundational step. By increasing the value of the underlying tooth structure, clinicians can work more conservatively with composite, relying on thinner, more translucent layers to achieve depth, vitality, and a truly lifelike result. Instead of compensating for darker substrate with opacity, the material can be used as intended, enhancing rather than masking, the natural optical properties of the tooth.   **The Bond: The Architecture Nobody Sees** A beautifully layered or bonded composite veneer on a well-whitened tooth is only as good as what holds it there. Dr. Bess has spent considerable time on one of the most misunderstood subjects in daily practice: adhesion. Seemingly every adhesive on the market claims high bond strength. Dr. Bess doesn't hide his skepticism about how that language gets used. "All the manufacturers claiming high bond strengths are pretty wild," he says. "I guess 'high' is a very relative term. 2 MPa is pretty high compared to zero." What he wants general practitioners to ask is simpler and more useful: what MPa can I realistically expect from this adhesive? Not what the marketing claims, but what the product delivers in clinical conditions. The answer to that question matters, because bond strength is a product of two variables that interact in ways practitioners often don't fully appreciate: the adhesive itself, and the clinician applying it. "Bond strength is heavily reliant on both the product and the doctor skill," Dr. Bess says. But the relationship between the two isn't symmetrical. "No matter how good your technique is, it can only be as good as the adhesive. If the adhesive averages 12 MPa, your attention to detail cannot overcome that deficit." The ceiling is set by the material. The floor, however, can drop dramatically with poor execution. "If your adhesive is capable of 65 \[MPa\] and you are sloppy, you could easily be averaging in the single digits. Both matter."   **The Technique That Changes How You Work** Once the substrate is set and the bond is solid, Dr. Fahl says there's a technique that a significant number of clinicians have never encountered and once they do, they tend not to leave it behind. The direct-indirect technique was first described by Dr. Nathan Birnbaum in 1992 and popularized, in large part, thanks to the lectures and writings of Dr. Fahl. The concept: composite is sculpted directly on the tooth structure without adhesive preparation, light-cured, then removed from the tooth. It's finished extraorally, heat-tempered for improved mechanical properties, and polished before being bonded back. All in a single appointment. The advantages over a conventional direct composite are substantial. Finishing extraorally means margins can be refined with precision that's difficult to achieve in the mouth. Heat tempering improves the mechanical properties of the restoration. The veneer can be tried in with modulating paste, allowing the clinician to fine-tune hue, chroma, and value before final cementation. Dr. Fahl has been performing this technique for more than 30 years, co-authoring *Composite Veneers: The Direct-Indirect Technique*, published in 2020. "Anyone who attends \[a lecture\] and gets stung by this bug, the direct-indirect bug, will never go back to doing a direct veneer ever again in their lives. With composites, that is." ![](https://info.ultradent.com/hubfs/Template/Blog/images/Icon_Mail.png) ### Ultradent Blog Sign Up to Receive Blog Updates ## Comments ### Recent Posts ![](https://info.ultradent.com/hubfs/Template/Blog/images/Icon_Mail.png) ### Ultradent Blog Sign Up to Receive Blog Updates ### Categories -
