Porcelain Fused to Metal
Porcelain fused to metal restorations have been the standard for decades. PFM crowns and bridges consist of porcelain fused to a cast alloy coping, or porcelain fused to Captek. We use only quality alloys and top quality porcelain, d.SIGN, from Ivoclar, for our PFM cases. We purchase our alloys from only reputable manufacturers that participate in the IdentAlloy program, so you know the nobility (semi-precious or precious alloy content) of the restoration you prescribe is the nobility of the restoration you receive.
Captek is an internally reinforced gold material that exhibits the color, workability and nobility of pure gold along with the strength and stability of the platinum/palladium family of cast alloys. It is not a cast alloy. The composition is 83.9% gold, 5.3% platinum, 7.3% palladium, 2.8% silver, and <1% iridium/ruthenium/rhenium. All elements are high nobility and high purity. Captek is not only strong and stable, but, unlike traditional alloys, non-oxidizing and non-corrosive as well. This means that gray lines at the tissue are permanently eliminated.
The gingiva is not only unaffected by Captek, but has a positive effect. There is less gingivitis and recession around a Captek crown. Bacteria in the mouth can result in periodontal disease, bad breath, heart disease, lung infections and even a weakened immune system. Captek ‘composite metal’ restorations are actually clinically proven to minimize bacteria and plaque build-up by at least 71% vs. natural healthy tooth structure*, helping to maintain and often improve your overall oral health.
We are an Advanced Certified Captek laboratory.
PFMs Utilizing Cast Alloys
We use only the finest alloys for our products, and we believe in the IdentAlloy program. Please click
here to learn more about the IdentAlloy program: http://www.identalloy.org/identalloy. Additionally,
the composition of the alloy used will be printed prominently on the invoice for each case. Our PFM
restorations are available in the below alloy options.
- Non Precious
- Semi-Precious (Noble) alloy
- Precious (High Noble) White alloy
- Precious (High Noble) Yellow alloy, 73% gold
We can also accommodate pink porcelain requests when the need exists to replicate tissue due to recession or bone loss. Simply provide us with a shade guide for the tissue shade you’d like us to match, or provide us with an Ivoclar Gingiva shade, G1 through G6, and we’ll create the appearance of tissue where needed.

IPS d.SIGN ® Porcelain
IPS d.SIGN porcelain, by Ivoclar, provides aesthetics at its very best. The fluorapatite leucite glass-ceramic features true-to-nature properties ranging from the light optical features to the enamel-like abrasion behavior. The unique combination of fluorapatite and leucite crystals disperse light throughout the ceramic in a manner that closely matches that of natural dentition. Because it is low-fusing, d.SIGN porcelain exhibits wear characteristics more comparable to natural enamel than feldspathic ceramics. Restorations made of d.SIGN porcelain can be efficiently finished and quickly polished once they have been seated. We use d.SIGN porcelain on all our PFM cases.
- The true-to-nature light scattering with the high translucency and brightness of the ceramic enable thorough masking of the metal framework
- Well-balanced relationship between chroma and brightness similar to the natural
- High surface quality, higher antagonist friendliness than other ceramic materials
