crowns-lava rsCrowns with Space Healthcare

At Space Healthcare we can create strong, tooth-coloured dental crowns that don’t contain any metal, using technologically advanced materials like alumina- or zirconia-based ceramics.  Crowns made from these materials can look fantastic and mimic all the characteristics of a natural tooth. For the very best  results, all-ceramic crowns are the treatment of choice.

The Development of Dental Crowns

Well into the second half of the 20th century, crowns placed on teeth towards the back of the mouth were always made out of gold, and those on front teeth were made from a fairly weak ceramic called feldspathic porcelain. These  solutions were the best available, given the technology and materials science of the time.

Gold was a convenient solution for restoring back teeth, as it’s undeniably a very strong material, but aesthetically the results were not pleasing. For front teeth, the feldspathic porcelains available at the time looked good, but were not particularly strong and had an unfortunate tendency  to break –usually when least expected, and inevitably at the most socially awkward moment!

A significant advance came in the 1960′s through the efforts of researchers in the UK :  it became possible to fuse porcelain to a metal inner layer, so that the crown was tooth-coloured, but had the reinforcement of metal inside. Unfortunately, early versions of this type of crown suffered with fairly poor appearance, as disguising the metal beneath the surface layers of porcelain was difficult to achieve.

These porcelain fused to metal crowns (PFMs) are still used at both the front and the back of the mouth but, as dental technology has improved, it is now possible to achieve much more aesthetically pleasing results.

It is also now possible to make very strong, tooth-coloured dental crowns without any metal inner layer being used at all, using the latest alumina and zirconia -based ceramics

Ceramic Crowns

Ceramic advanced crowns are a state-of -the art dental solution. By using exceptionally strong types of ceramic material it’s now possible to construct  life-like crowns which do not need a metal inner layer to give them strength. The resulting crown has a level of translucency and opalescence like a natural tooth, so we can create crowns to complement and enhance your smile rather than just looking like crowns!

Several types of ceramic advanced crowns are available. Rather than using a single type, at Space Healthcare we use the ceramic most suitable for your particular circumstances.

Some crowns have an inner layer of extremely tough ceramic, such as alumina or zirconia, together with an outer porcelain layer to give superb aesthetics; Procera ® and Lava® are well-respected brands that can give excellent results.

One of the most exciting materials which can now be used for advanced crowns is lithium disilicate. This material is actually termed a glass-ceramic, and at Space Healthcare we use IPS e.max ®. This material can now be used to make beautiful crowns that are resilient and attractive at the same time. A winning combination!

Zirconia Ceramic Crowns

For creating crowns in areas where the greatest strength is needed  (usually on your back teeth) we can use an immensely strong all-zirconia ceramic.  This really is a superb material –not only is it strong, but it also looks great too.

The ultimate crown!

The amount of tooth preparation required for this type of crown is less than other tooth-coloured  all-ceramic crowns, and this has the advantage of preserving more of your tooth tissue.

Dentine Bonded Crowns

Dentine is the middle layer of the tooth, underneath the enamel.

A dentine bonded crown is a very thin, ceramic-only crown, which is bonded to the dentine and acts very much like an artificial enamel layer.

Dentine bonded crowns are often made from feldspathic porcelain, which is not intrinsically a strong material. However, they gain their strength from the very strong bond to the underlying tooth that can be created using the latest, highly advanced dental bonding technology.

As well as being strong, they can be very attractive and natural in appearance and they have the added bonus that, because they are so thin, less preparation of the underlying tooth is required than with other types of ceramic crown.

Dentine bonded crowns are not suitable for every situation and so it is vital that you have a detailed dental consultation first to understand if they are the right option for you.

At Space Healthcare our experienced dental team will be happy to discuss dentine bonded crowns with you as part of your dental consultation.


Porcelain Fused to Metal Crowns

For many years this type of crown has been the most common tooth-coloured crown provided in the UK. A combination of a strong metal core surrounded by an outer layer of tooth-coloured porcelain allows a crown that is strong but also fairly aesthetic.

Many different types of porcelain fused to metal crown exist, from crowns where the metal is a grey, non-precious alloy, to crowns where the metal is a precious, yellow gold alloy. These yellow gold containing crowns can be made to appear warmer and more natural as the yellow gold alloy imparts a similar tone to the yellow dentine inside a natural tooth.

Porcelain bonded to metal crowns offer true value for money. Less expensive crowns using grey, non-precious metal alloy cannot hope to achieve the high levels of aesthetics required for the crown to truly blend in with the natural teeth and to enhance the smile.

At Space Healthcare we offer porcelain bonded to metal crowns constructed to the highest standards to surpass your expectations.

Gold Crowns

Gold crowns are used mainly on your molar teeth, for the simple reason that they are not tooth-coloured. Gold alloys used in dentistry are extremely strong and long-lasting and as a result gold crowns can last for a very long time.

The amount of tooth preparation required for a gold crown is less than for all but the most advanced tooth-coloured  all-ceramic crowns, and this has the advantage of preserving more of your tooth tissue.

Gold crowns are very gentle and non-abrasive to your other teeth and may be the best option for you if you have a very strong bite or a grinding habit (bruxism or parafunction).

At Space Healthcare we offer gold crowns as one of our comprehensive range of crown alternatives. In some situations gold is the best option and it’s certainly true that many dentists have selected gold for their own crowns on their back teeth. At your detailed dental consultation we will discuss all the options with you so that you can make an informed decision on the best choice for you.

Gold Partial Coverage Crowns

This special type of gold crown has the advantage of not covering the outer portion of the tooth so that the natural enamel can be left in place.

For areas visible in your smile this can give you the advantages of a tooth-coloured outer portion of your tooth with the strength and long term stability of gold for the biting surface and the rest of the tooth.
