Making Conservative Restorations More Accessible: Additive Dentistry and Your Practice
September 20, 2022 | Dr. Shira Zary
When it comes to esthetic dentistry, patients have high expectations. Direct composites are both an affordable and conservative option for creating beautiful, esthetic restorations and, in some cases, offer a welcome alternative to porcelain veneers. While creating “freehand” direct composite veneers can be technique sensitive and time-consuming, we have seen an evolution in both products and techniques that make these restorations easier to create, further expanding the tools at the clinician’s disposal.
Additive composite techniques support minimally invasive dentistry
Minimally invasive dentistry is a treatment philosophy that involves choosing the most conservative option for every clinical decision. According to an analysis published in the November, 2021 issue of The Journal of Prosthetic Dentistry, “Considerable advancement has been made in minimally invasive dentistry, as demonstrated by the increase in the number of publications linked with collaboration among various authors, nations, and institutes.”1 Along with increased research on the topic, clincians report that more and more patients are expressing a desire to preserve their natural tooth structure, for example, after orthodontic treatment. Porcelain veneers require, in many cases, tooth preparation and removal of healthy enamel – but with additive composite techniques, we can offer patients a non-invasive, conservative, and esthetic alternative.Benefits of additive composite dentistry
Direct composites present a number of advantages for both patients and dental practices, including conservation of tooth structure, the ability to provide same day dentistry, repairabilty, and affordability. Composites have become the obvious choice for small fractures and carious lesions in the anterior region, and are also used extensively to restore larger coronal defects. New matrix systems further facilitate the use of advanced composite materials in practical, predictable ways for more challenging clinical cases, like closing black triangles and creating ideal tooth contours in multiple-unit anterior cases, as seen below.

In addition, opaquers are available to mask darkened enamel, tetracycline stains, and even amalgam tatoos, thereby providing a clean canvas on which to create a natural-looking, esthetic restoration. For patients who are considering a cosmetic change to their smile, it’s often comforting to know that composites are easy to adjust, modify and repair as needed, as opposed to indirect porcelain veneers. Additionally, composite restorations wear similarly to natural tooth structure, while insufficiently polished porcelain may wear the patient’s opposing dentition.2
