Tooth Crowns in Chatswood
Dental crown is a dental restoration that works like a helmet that protects a tooth from vertical split or restoring a
heavily broken down tooth. It can be made of many different types of materials, ranging from gold, stainless steel, porcelain fused to metal (PFM), porcelain fused to zirconia (PFZ), monolithic ceramics such as Emax or zirconia, as well as the new generation hybrid ceramics (fusing ceramic and resin matrix).
At our practice, we offer:
Gold alloy as a dental restorative material is extremely resilient yet wears at a rate similar to tooth structure. If not for the fact that it does not look like a tooth, it remains one of the most popular choice amongst restorative dentists and specialists.
Porcelain fused metal crown
Dental ceramic can be fused to a thinner metal coping to mimic the aesthetic of a tooth. This type of crown is still the most popular type of crown used in Australia, but some significant drawbacks have led to its gradual decline in preference amongst dentists. The combined thickness of metal coping and porcelain meant that the crown will either be quite bulky, or more tooth structure need be cut away to accommodate the thicker crown layer. Further, the porcelain is prone to cracking and wear which overtime exposes the metal coping and becomes less aesthetic. Of course, chipping of porcelain is simply an aesthetic drawback and in less aesthetic demanding situation this is still a suitable option.
Porcelain fused zirconia crown
Similar to PFM, porcelain fused zirconia crown uses a thin zirconia coping (strongest dental ceramic available) and porcelain fused to its surface to provide its aesthetic. Zirconia has the advantage over metal coping in that it looks more like teeth than metal coping. However this doesn’t eliminate the problem of porcelain chipping but is at least more tolerable than metal coping showing in more aesthetically demanding situations.
Monolithic zirconia crown
This option eliminates the risk of porcelain chipping and the crowning teeth can be made thinner than PFZ or PFMs. Zirconia is an extremely rigid and strong ceramic and can withstand most dental functions with little risk of fracture. Aesthetic is adequate but due to the nature of material (metal crystal oxide) it exudes a slight metallic tinge and also is insufficiently translucent in aesthetic demanding situation. Material advancement is improving its translucency but strength is also compromised and may not be sufficient to mask out dark underlying tooth structure.
Monolithic Emax Crown
This is currently one of the most used dental ceramic in the world for its strength and aesthetic properties. Emax can be modified to enhance its aesthetic properties via cutback layering, staining, or simply just match adjacent teeth’s colour. Our in house cadcam machine can produce such crown in a single visit minimising your time away from your busy lifestyle.
Hybrid Ceramic Crown
The advancement in dental technology and material research have led to the development of this new age material, which combines the resiliency of dental resin and the hardness and aesthetic of dental ceramics. It has a kinder wear to natural teeth for dental grinders and decent aesthetic and strength to be used in most circumstances. Our in house cadcam machine is able to produce a hybrid Ceramic Crown in a single visit, minimising your time away from ones busy lifestyle.
