The notion of adding materials to teeth in order to change the way they look is nothing new to dentistry. Traditionally, teeth are prepared in some way or fashion in order to place and retain a restorative material — typically a filling, porcelain veneer or crown. Not only is tooth reduction generally necessary to restore lost or damaged natural enamel as a result of the ravages of tooth decay or trauma, but it is also necessary to create room to place an aesthetic and functional “restoration.”
The purpose of this article is to introduce and provide a clear understanding of an alternative cosmetic treatment option, the “no-prep” or “prepless veneer,” whereby no drilling is required to enhance a smile. It also endeavors to bring clarity and understanding to the numerous areas of confusion regarding this treatment modality. Most importantly, it examines the case selection process; when prepless dentistry will work and when it won’t. As with almost all dental and medical procedures, there are risks, benefits and alternatives. It is with the help of a dental professional experienced in these advanced techniques, together with your own goals and understanding, that you can make decisions that are right for you.
“Prepless veneers” is a concept that elicits various reactions and opinions among dentists, ranging from absolute disbelief that they can facilitate effective restorations, to appreciation for these conservative and advanced works of art! This range of opinion about a novel approach to cosmetic dentistry is vast and with good reason. The concept of “additive only” restorations intuitively causes the experienced clinician reason for concern as visions of bulky, over-contoured teeth quickly come to mind. Unfortunately, some prepless techniques and products circulated heavily in the media have shown thick, bulky looking restorations, causing skepticism among some dentists and consumers alike.
And yet, despite these concerns, an undeniable trend is emerging among many esteemed cosmetic dentists to incorporate not only minimal prep, but also “no-prep” restorations into their compendium of viable treatment options and alternatives.
In recent years, new developments in techniques and materials have resulted in a fresh look at the aesthetic possibilities for the no-prep veneer option. Cases done by talented dentists and lab technicians have produced results which would meet the highest standards in cosmetic dentistry [Figures 1 and 2]. Part of the advanced level of training for prepless veneers includes the important aspect of proper case selection. Not every situation lends itself to a no-prep approach, but when it does, the results can be not only beautiful, but also stable and reversible!
