THESE ARE AS FOLLOWS:

• The color of the natural tooth must be close to the desired color. Although some stains and surface abnormality hide by in addition of increased whitening with opacity, it can be achieved with very thin veneers, but inappropriate increased opacity to cover dark teeth will yield unaesthetic results so it’s only decided by the expert what should be done. Typically, it is advised that when using the correct ceramic, teeth can be whitened up to two shades whiter with prepless veneers.
• The profile of teeth must be as close to ideal as possible, or tongue side inclined. Although these veneers can be fabricated as thin as 0.2 mm, if the teeth are already lip or cheek side inclined, addition of front side porcelain will only exaggerate this situation. Prepless veneers are ideal when teeth are naturally inclined tongue side, because adding front side porcelain actually enhances the esthetics by increasing the reflective surface of the teeth.
• The teeth must be in ideal alignment (or close to it). Prepless veneers have become an excellent post-orthodontic treatment, especially in the case of microdontia (small size teeth) where there is a tooth-width, arch width discrepancy. If the teeth are misaligned, the final result will yield teeth that have significant different edge thicknesses. Also, not in ideal arch form that includes overlapping teeth makes it unavoidable concave surfaces and provide interproximal contours that appear natural.

Most lab technicians and clinicians feel that prepless restorations, because of their minimal thickness, should be made using a powder-liquid ceramic. We have noticed that pressed ceramic (IPS Empress) can be made in restorations as thin as 0.3 mm.

The prepless option can certainly yield aesthetics that against traditionally prepped veneers. Some clinicians in dentistry believe that you cannot achieve a satisfactory esthetic outcome using prepless veneers. But we have noticed that if you have a thorough knowledge of prepless veneers – when and how to use them – and follow several indications, which we detail here, you can achieve a very attractive result.

We at Dr. Narmatha’s Dental care need to analyze your smile to be sure that you are a candidate for prep-less veneers.
