Procera Alumina makes for very aesthetic and life-like crowns and bridges. Alumina core material is more translucent than zirconia, yet will mask out all but the darkest underlying colour.
We use the newest NobelBiocare scanner in-house to create these CadCam cores and layer Vita® VM7 porcelain on top. Alumina is not as strong as zirconia and so these crowns are recommended for the anterior region where aesthetics dictate.
Procera Zirconia substructures are extremely strong and recommended for placement anywhere in the mouth. Zirconia is rather opaque and will mask out the underlying tooth structure, but therefore doesn’t have the life-like translucency of Alumina. Vita®VM9 porcelain is layered on top.
While we routinely fabricate NobelProcera Zirconia substructures, if you prefer we will provide 3M ESPE Lava™ Zirconia substructures. Whichever one we use will be layered with Vita®VM9 porcelain on top.
Ivoclar’s e.max® (lithium disilicate) is a tremendously strong material that can be used by itself (monolithic) or layered with porcelain for an even more aesthetic appearance. Crowns and bridges can be bonded or cemented. We use e.max for crowns, small bridges (up to 3 units), veneers and inlays-onlays. It can be milled or pressed to the desired form and comes in many translucencies.
The material is particularly good for masking out underlying tooth colour.
While Empress has had a place in dentistry for many years we currently use it only for veneers. It is not as strong as e.max but very beautiful.
As veneers do not benefit anyway from the extra strength of e.max, this is a perfect application for this material.
Ivoclar also makes a product for post cores called Cosmo-Post. It consists of a zirconia post to which an Empress material is pressed. These are very strong due to the zirconia post.
IPS e.max® Preparation Guidelines
Proper preparation is critical to the success of any restoration. The recommended preparation guidelines for IPS e.max lithium disilicate are similar to other restorative systems. There is no difference in the recommended occlusal reduction for IPS e.max lithium disilicate versus Lava and porcelain fused to metal posterior restorations.
IPS e.max® Cementation
E.max crown & bridge can be cemented or bonded, while veneers must be bonded. IPS e.max offers options for cementation. Restorations with a retentive preparation form can be conveniently cemented with conventional cement. You may also choose adhesive cementation.
Porcelain to Metal (PFM)
Crowns and bridges made with the porcelain-metal technique have been around a long time because they’re successful. We’ve been making them for over 25 years and consistently deliver PFMs to the highest standards. We produce PFM crowns, bridges and maryland bridges using a variety of materials and techniques. Vita™VMK Master porcelain is layered on top of our alloys.
In today’s dental practice environment, we need to offer a range of options to suit the diverse needs of patients. As the price of gold has continued to skyrocket and seemingly taken other precious metals with it, we have researched the market and procured alloys to suit most applications and resources.
We use a variety of precious alloys with varying ratios of gold and palladium. We only use high quality noble alloys (high in either gold, palladium or both).
Base Metal Alloys
We use fully biocompatible non-toxic base metal alloys that are nickel, cadmium and berrylium free. We have the option to cast these restorations or create them using the CAD/CAM technique. In either case you can use them with complete confidence in their quality and safety. These are typically cost efficient restorations and an excellent choice if you are looking for a PFM offered at a flat fee.
This is a NobelProcera™ alloy that is fully biocompatible and nickel, cadmium and berrylium free. It is a precision milled restoration that we create using CAD technology.
Indicated for crowns and bridges up to 6-units (on teeth and abutments), for any position in the mouth.
Conventional or temporary cementation.
We still do all metal crowns, ¾ crowns, inlays/onlays and post cores. We fabricate them from a variety of noble or non-noble alloys as desired.
