We’re here to break this down for you, and make it as simple and informative as we can! At Pleasantview Dental Art, our team is continuously learning and staying updated with the most recent developments and innovations to improve our capabilities and products.

Zirconia Full Contour (FCZ)

Designed by technicians and milled in-house with discs of zirconium dioxide using CAD/CAM technology, full contour zirconia restorations are ideal when durability is of the highest importance as it offers superior strength compared to full porcelain restorations and better aesthetics compared to PFM restorations.

From an aesthetic standpoint, monolithic solid zirconia is more opaque than its layered counterpart, making it unsuitable for anterior restorations. However, due to its lack of translucency, it is very effective at masking darkness from discoloured stumps or from a post and core. For posteriors, full zirconia is the clear choice as it is extremely durable, making it a great option for patients with severe bruxism or minimal clearance. Generally speaking, less prep is required with zirconia crowns. With its excellent biocompatibility, crowns and bridges prepared from zirconia are extremely safe for clinical use inside the mouth. Although zirconia has been extremely promising, it is still quite new in its development and there isn’t much data on how long zirconia restorations will last. Being extremely hard, it is also notoriously difficult to adjust in the mouth or remove when necessary. Regardless, Zirconia has quickly become one of the most popular materials available today and is available in Zirconia HT (High-Translucency), Zirconia Solid, and Layered Zirconia.

At Pleasantview Dental Art, we mill the large majority of both our anterior and posterior restorations from reputable mono and multilayered Zirconia discs for high aesthetics and great durability.

Layered Zirconia (PFZ)

Layered zirconia restorations consist of a milled zirconia substructure or coping that is veneered with porcelain. After the zirconia substructure is designed and milled, our technicians carefully layer porcelain for the most aesthetically pleasing and natural fit for your patient, while leaving the area of contact porcelain-free for durability.

Highly suitable for both anterior and posterior restorations, layered zirconia crowns and bridges provide the ultimate combination of aesthetics and strength available today with high translucency and opalescent characteristics. Layered zirconia offers strength and durability that is comparable to PFM restorations but with far superior aesthetics and no metal. Zirconia HT (High-Translucency) offers less translucency when compared to e.max, but is much more durable than the glass-ceramic and even with layered porcelain, fracturing is rare. With clear advantages and very little downside to layered zirconia, it has become a great option for highly aesthetic restorations.

For all aesthetic cases, Pleasantview Dental Art offers complimentary custom shading appointments with our experienced ceramists who gather information on the intricate nuances and characteristics in colour, hue and chroma for a precise and aesthetically-pleasing dental restoration.

IPS e.max® Press

Pressed from e.max can be used for veneers, crowns, bridges, inlays, and onlays. Known for its exceptional life-like qualities and incredible translucency, this monolithic lithium disilicate glass-ceramic allows for beautiful natural aesthetics while providing great durability and strength.

E.max restorations provide a great option for highly aesthetic cases requiring the maximum translucency. This highly translucent nature or e.max also makes it unsuitable for dark stumps and post and core treatments and zirconia may present a better option in these circumstances. In addition, due to the the low flexural strength of e.max, bridges are usually no more than 3 units up to the second pre-molar and are not recommended for patients with heavy bruxism. As with zirconia, being free of metal makes it a great option for receding gumlines as it eliminates the unappealing dark line typically found in PFM restorations.

There are two methods to fabricating IPS e.max restorations: pressing and milling. The pressing method involves waxing up the restoration, investing and burning out the wax, and then pressing the superheated lithium-disilicate into the negative space left from the burned-out wax. The milling method involves using milling machines to cut or grind down lithium-metasilicate blocks into the desired shape.

At Pleasantview Dental Art, we choose to only press our IPS e.max crowns as it has been shown to have better fatigue performance in comparison to CAD/CAM milled crowns.

Porcelain Fused to Metal (PFM)

The time-tested PFM crown offers the strength and durability of a metal substructure with the aesthetic properties of a fused porcelain surface. The metal substructures, which are made up of non-precious, semi-precious, or high noble dental alloys, are layered with feldspathic porcelain.

Although PFM restorations have an impressive clinical record for success, the number of PFM crowns by clinicians has been decreasing in recent years, with the introduction of materials like zirconia. The metal substructure of PFM restorations provides great strength making it an extremely durable option for longer bridges but this metal can also make it more difficult to create truly aesthetic crowns and bridges compared to its all-ceramic and zirconia counterparts. To hide the metal collar or notorious “dark band” resulting from receding gums notorious “dark band”, facial or lingual porcelain butt margins can be requested during fabrication for a more aesthetic result. It is also useful to know that the feldspathic porcelain that layers PFM restorations wears opposing teeth at the highest rate compared to harder materials like zirconia.

There are two methods to creating the metal substructures that make PFM crowns. The first is the traditional method that involves waxing, investing, casting the alloy, divesting, and finishing. The second method involves CAD/CAM design and advanced milling.

Although there are a variety of coping metals available on the market, Pleasantview Dental Art only uses quality biocompatible alloys to prevent or minimize potential allergic reactions to PFM restorations.

Full Metal Restorations (FGC)

Full metal crowns & bridges are the standard for proven long-term durability of posterior crowns and remains a popular choice for many patients and practitioners. Cast gold is the best indirect restorative material we have in dentistry today but it is also the least aesthetically pleasing.

Diagnostic Wax-ups

A wax-up gives both the clinician and patient the opportunity to visualize the results of a restoration prior to the treatment and allows for better understanding during preparation.

Polymethylmethacrylate (PMMA)

PMMA is used to fabricate temporary dental restorations for a wide range of cases, and are milled in-house.
