All Ceramic Restorations
All ceramic restorations have been to go to restoration for many doctors. With so many options to choose from sometimes it can be difficult to figure out what material is good for what indication. Here is a list of some of the materials that we use.
IPS e.max Press
IPS e.max Press are lithium dislocate glass-ceramic ingots for the press technique.
The innovative IPS e.max Press lithium disilicate glass-ceramic (LS2) offers excellent fit, form and function combined with high strength of 500 MPa. The material is supplied in seven levels of translucency and ingot two sizes. The resulting restorations exhibit lifelike aesthetics, regardless of the clinical situation.
IPS e.max Press is used to produce single-tooth restorations, bridges for the anterior and premolar region, inlays, onlay, implant superstructures and custom implant abutments.
A wide selection of ingots are available from which users can choose to suit their preferred processing technique (staining, cut-back or layering technique) and clinical demands. The restorations are characterized or veneered with coordinated staining materials or layering ceramic from the IPS e.max Ceram assortment. Materials intended for full-contour restorations are available in 16 A-D and four Bleach BL shades. The substructure materials for the layering technique are supplied in varying levels of chromatic shades.
Available ingots
Multi ingots
These polychromatic and polytranslucent ingots provide a natural shade progression from the margin to the incisal edge, and enable technicians to achieve a strong and highly aesthetic restoration without needing to cutback and layer.
HT ingots
The high translucency ingots (HT) are ideal for the fabrication of minimally invasive full-contour restorations, such as inlays, onlays and veneers. The restorations can then be characterized with staining materials in the IPS e.max Ceram line.
MT ingots
The medium translucency ingots (MT) are perfect for a variety of indications from thin veneers to 3-unit bridges and are ideal for restorations requiring a higher brightness level than HT and more translucency than LT.
LT ingots
Full-contour partial crowns and crowns are fabricated beautifully with the low translucency ingots (LT). In the anterior region in particular, the esthetic appearance of the restorations is maximized by employing the cut-back technique.
MO ingots
The medium opacity ingots (MO) are used to fabricate substructures for vital or slightly discolored teeth. They create an ideal basis for lifelike restorations completed with the layering technique.
HO ingots
In cases where the prepared tooth structure is discolored or titanium abutments are used, the HO ingots mask the dark background to achieve highly esthetic results.
Impulse Opal ingots
The best option for enamel replacement. Restorations fabricated with these ingots exude exceptionally opalescent properties making them ideal for (thin) veneers with light teeth requiring an opalescent effect.

IPS Empress CAD
IPS Empress CAD is a leucite-reinforced glass-ceramic block for the CAD/CAM technology.
IPS Empress CAD is suitable for the fabrication of highly aesthetic monochromatic single-tooth restorations, such as veneers, inlays, onlays, anterior and posterior crowns. With its homogeneity and light scattering behaviour, IPS Empress provides a balanced chameleon effect. In addition to the light-optical properties, IPS Empress CAD restorations are distinguished for their lifelike translucency, high aesthetics, and a flexural strength of 160 MPa.
HT Blocks
The IPS Empress CAD HT blocks with high translucency are mainly used for the milling of smaller restorations (e.g. inlays), due to their lifelike chameleon effect.
LT Blocks
Thanks to their chroma and brightness value, the blocks with lower translucency (LT) are ideally suitable for the fabrication of larger restorations (e.g. partial crowns, crowns).
Multi Blocks
The polychromatic IPS Empress CAD Multi blocks are the highlight of the IPS Empress CAD range of products. Given their true-to-nature shade and fluorescence transition between the dentin and the incisal areas, they provide restorations with a maximum of aesthetics and lifelike appearance even without characterization.
IPS Empress CAD blocks can be milled in the Ivoclar Vivadent PrograMill One, the CEREC System (Siren) and Planmeca FIT System (E4D Technologies).
IPS Empress CAD – The highlights
- Twenty years of clinical experience with more than 40 million seated restorations
- Leucite glass-ceramic (160 MPa) for exceptional aesthetics
- Comprehensive shade and size range for every patient situation
- Choice of true-to-nature chameleon effect, lifelike brightness value or natural shade gradient
- Polishing with OptraFine – no glazing necessary Indications
- Veneers
- Inlays, onlays

Ceramic Inlay/Onlay
Inlays and Onlays are generally chosen for aesthetic reasons. They can be a great alternative to traditional amalgam fillings.
There are a variety of options to choose from when fabrication a inlay/ onlay. These restorations can be made from everything using e.max (press or CAD), VITA enamic, and a variety of others.

Full Contour Zirconia Crown
Monolithic zirconia are probably the most popular restorations. They are made to withstand patients with bruxism while also maintaining a high aesthetic. We use a variety of different zirconia materials varying from zirconia used for anterior restorations to high strength posterior zirconia and high strength zirconia used for long span bridges and all-on-4 restorations.
High Strength Zirconia
7-layer (4 layers plus 3 transition layers), tanslucent zirconium with higher translucency and high bending strength (about 1100 Mpa) for copings and fully anatomical restorations for up to 14 units. In the production process, 4 layers of pre-coloured zirconium are layered on top of each other, building 3 transition layers in the process. The result is an extremely natural colour transition for vivid, lively restorations. This is a high quality superior zirconia that is made in Germany.
Anterior Zirconia
Cubic, isostatically pressed zirconium with highest translucency for anterior- or posterior restorations with up to 3 units. Bending strength about 600 Mpa. This high translucent zirconia allows for 20% more light transmission than other like zirconia. It also has more that 65% higher mechanical strength properties than compared to lithium disilicate glass

Layered Ceramics
Even though monolithic zirconia is very popular we also understand the aesthetic demand for anterior teeth. This is why we also offer our clients a ceramic substructure with layered porcelain. We can layer from the standard vita shade guide to the Vita 3d shade guide.
Preparation Guide:
The ideal preparation for PFZs is a chamfer margin preparation. If a porcelain labial margin is prescribed, then a shoulder margin preparation is required.
Feather-edge margin preparations are indicated for full-cast restorations.
Recommended Cements:
Resin Ionomer cement (RelyX or RelyX Unicem, 3M ESPE)
Maxcem Elite (Kerr)
Panavia F 2.0 (Kuraray) -ideal for short, tapered preparations
Glass ionomer cement (GC Fuji, GC America)Refractory Veneers
This is one of the highest aesthetic option available. These lifelike restorations are made only by the most accomplished ceramists. These restorations require specific parameters in preparation of the teeth. For more information regarding these restorations please call the lab directly.
In the crown and bridge sections please look at this error
Varieties include:
Porcelain fused to metal crowns using a precious semi, or non precious metal substructure that is covered up with highly aesthetic porcelains,
All-ceramic crowns that contain no metal.
Gold crowns, recommended for posterior teeth and also patients with a heavy bite and minimal occlusal space.
Porcelain Fused to Metal Crown
These classic restorations have been used for many years and have proven to stand the test of time. These crowns are made using a metal substructure with porcelain applied on top. Some of the varieties of metal that we use here at the lab range from a very high content yellow gold substructure, to a high palladium gold substructure, titanium substructure which is classified as a high noble alloy. Some economical alloys that we can offer are a semi precious and the most economical of them all the non precious metal substructure. Please contact the lab directly for more information or specific details about the variety of metals available.
Full Gold Crowns
Full gold crowns have somewhat lost their popularity over the years. Even though all ceramic crowns have really taken over the industry thats not to say that these restorations have been completely eliminated . They are still used to this day because they can be made very thin and sometimes they really are the only option. The benefits are that they are very gentle on opposing dentition. With the variety of alloys on the market today they can be made using alloys with a very high gold content to semi precious yellow gold and even a non precious that is yellow in colour.
Please contact our metal department for more information on alloy selection.
Gold Inlay/Onlay
Gold Inlay/Onlays can be fabricated using the same golds as a full gold crown. These are great for patients that do not want to have amalgam fillings. They are also a tried and tested restoration that have been proven to be long lasting. Some of the benefits to having these restorations is that they can be made very thin. They do not have chipping like their all ceramic counterparts. Some of the drawbacks to these restorations is that they are made from a metal that is not the same shade as natural dentition so they can stand out. They may not be suitable for people with sensitivity to metals. Please contact the lab for more information regarding these restorations.
Preparation Requirements:
Inlays and onlays can also be fabricated as a full-cast restoration. Feather-edge margin preparations are indicated for full-cast restorations, but any margin preparation may be used.
Recommended Cements:
Panavia 21 (Must be tinplated if precious metal is used)
Glass ionomer cement (GC Fuji, GC America)
Zinc Phosphate Polycarboxylate Resin Ionomer cement (RelyX, 3M ESPE)
All castings are made with a metal alloy, be it non-precious, semi-precious or precious metals. Alloys are classified by their content.
