In most cases, when matching a veneer restoration to natural dentition, a lithium disilicate (IPS eMax) material such as Burbank Dental Lab’s Nano® Press & Layered Veneers are ideal material choices. In some cases, feldspathic porcelain veneers are the best option.
Nano Press & Layered Veneers
Nano Press & Layered Veneers should be requested when a more aggressive preparation is needed. For example, these veneers work well where a shade correction is required. This option is ideal when a shift in color of up to three steps is necessary to match dentition properly. These veneers are pressed and then layered and come in ingot shades that vary in color and opacity levels.
Preparation design:
- Reduce the facial enamel by .5 mm to .7 mm
- .3 mm chamfer margin at or slightly subgingival
- Extend the prep into the interproximal contact area about halfway
- Incisal “butt joint” preparation with .75 mm to 1.5 mm reduction.
Feldspathic Porcelain Veneers
Feldspathic porcelain veneers are entirely layered to mimic natural dentition. They are great for cases where unfavorable underlying colors, such as those found in tetracycline cases, need to be blocked out to match the natural dentition properly. These veneers can mask out severe discolorations while providing a very natural translucent result. They are fabricated using either foil or refractory die.
Preparation Design:
- Labial tooth preparation – .8 mm to 1.0 mm
- Create a .3 mm chamfer margin
- Extend the prep into the interproximal contact area about halfway
- Incisal “butt joint” preparation with 1.0 mm to 2.0 mm reduction.
Each case must be evaluated separately. The preparation can vary and require variation from the above recommendations. It is critical to review all of the information on the case and then prepare the case accordingly.
The following case was presented with two old composite veneers on tooth numbers 8 and 9. The patient’s biggest concern was the discoloration that had developed over time. There were also some shape issues. After receiving the color information and noting the underlying color, it was determined that Nano Press & Layered Veneers would provide the best results.
It is crucial to try in the veneers with try-in gel before cementation to evaluate color and shape before the final cementation. This case resulted in a more harmonious result with the restorations matching the color and shape of the existing dentition beautifully. This outcome is achievable when proper communication is provided.
Matching a single anterior veneer to natural dentition is a challenge and many factors can affect the outcome of a case. Fortunately, providing the right information to the laboratory helps to manage the success of these cases. Informing the patient of the difficulties involved is paramount in managing the expectations of the patient.
Today, we have various material options that can provide successful results in just about every situation without being adjusted repeatedly.
