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 or our SimplyThin Veneer 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 1.00 mm to 1.50 mm
- Create a .3mm chamfer margin
- Incisal "butt joint" preparation with .75mm to 1.5mm reduction.
- The facial plane at the incisal edge needs to be prepped at a retroclined angle.
SimplyThin Veneers
SimplyThin Veneers can be used when minor color changes are needed, and no major alignment issues are present. These restorations are fabricated to full contour and then stained. A glaze layer is added over the stain. These are best in cases where minimal preparation is required.
Preparation design:
- Reduce the facial enamel by .5mm to .7mm
- .3mm chamfer margin at or slightly subgingival
- Extend the prep into the interproximal contact area about halfway
- Incisal "butt joint" preparation with .75mm to 1.5mm 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 .3mm 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.
