Zirconia Crowns and Bridges
Both crowns and bridges are fixed prosthetic devices, unlike dentures which are removable. This means they are cemented onto existing teeth or implants and can only be removed by a dentist.
Dental Crowns are custom-made, permanent restorations. They are essentially a small cap that is placed over a natural tooth, or on top of an implant, and completely covers the entire visible portion of the tooth that lies at and above the gum line.
A Dental Bridge may be recommended if you are missing one or more teeth. They span the space where the teeth are missing, anchoring themselves to either the natural teeth on either side, or dental implants. These teeth are called abutments and serve as the anchor point for the bridge, while the teeth in between are called pontics.
When should Crowns and Bridges be used?
There are several cases which prompt the need or desire to have crown or bridge restorations done. In general, they are used to restore strength, functionality, shape and size to a tooth, or teeth, and to improve the aesthetic appearance of your mouth. The following are examples of situations where a crown or bridge could be a potential solution.
- To protect a weakened tooth that has been afflicted with decay or fractures, by holding it together and preventing it from breaking further.
- To replace an old, broken or failing tooth filling.
- To restore an already broken tooth.
- To restore the length of a worn down tooth, or teeth (for example, from grinding).
- To cover and support a tooth that has little natural tooth structure left.
- To make cosmetic modifications to straighten or reshape teeth, or to close spaces between teeth.
- To fill in gaps from missing teeth using crowns and bridges.
- To place on top of an implant.
- To restore any tooth that has undergone root canal therapy (Generally recommended in all cases).
Crowns and bridges not only restore the aesthetic parts of your teeth, but also provides more durability and strength to protect your teeth from further wear and breakdown.
What makes Zirconia Crowns and Bridges special?
Zirconia is becoming one of the most popular material choice for dental crowns and bridges. Zirconia Crowns are the hardest and strongest type of ceramic crowns available. It is a type of crystal that is virtually indestructible and incredibly durable, which is what allows them to withstand biting and chewing forces, and wear and tear for such a long time.
The Zirconia crowns are also easy to modify according to the set of teeth it will be placed alongside. It can be shaped to look even better than the original, giving you the best looking smile possible. Zirconia is biocompatible, which means it is safe to stay in your mouth for a long time without any adverse or allergic reactions, and is generally very hygienic.
Because Zirconia Crowns are milled from a chunk of crystal, they are guaranteed to be at least 5 times stronger then porcelain crowns, and provide a far more natural looking appearance. Our preferred laboratory located in Penrith NSW, use two particular kinds of Zirconia, allowing for more tailored solutions to both your anterior and posterior teeth.
What do the procedures involve?
Each individual case may vary, but as a general overview the following is to be expected:
- An examination or consult will be required for both your tooth and overall mouth, this may include x-rays.
- If there is extensive decay, or risk of infection then root canal treatment may be required initially.
- If there is not enough natural tooth structure left to securely hold the crown in place, then you may be required to have a core, or post and core first to stabilise and strengthen the tooth.
If these treatments above are needed, you will be given a treatment plan, treatment information, and estimated costs. You will then require two appointments for the crown.
- The first appointment involves examining and preparing the tooth, making impressions, filing down the natural crown along the chewing surface and sides to make room for the Zirconia Crown to for on top. After this an impression is made for the crown to be moulded to, and to make sure the crown fits your natural bit correctly. Then a temporary crown will be made and secured with a temporary cement until the lab has finished making your permanent Zirconia crown or bridge.
- Your teeth impressions are then sent off, along with the shade for the tooth or teeth to match the rest of your natural teeth. This will take up to two weeks to be manufactured.
- At your second visit, the temporary crown will be removed and the colour and fit of your permanent crown will be checked. If it is all satisfactory, then your new crown will be cemented into place.
In the case of bridges, multiple preparations on the teeth involved would require a longer first appointment and the same for the second appointment. In the case of particularly large cases, the lab may take longer than two weeks to get the finished product back to us.
Full Arch immediate Denture - DAVIS Bridge
The Davis Bridge is a significant advancement over existing systems because it incorporates the use of a titanium bar into the design that makes the bridge much stronger. The advanced design is also far more practical as the bridge is luted to the bar and, if required, can be easily removed again and serviced.
The Davis Bridge is a simple two piece design, with the bridge being milled from a single piece of Zirconia, and the titanium bar. In the very unlikely event the implant fails, the bridge can be disassembled and the components individually retrofitted, eliminating the need for total remakes and further costs.
Davis is confident in the combination of Zirconia and Titanium, so much so that they offer a 10yr warranty on the Zirconia Bridge. The Zirconia and titanium materials are inherently strong and being biocompatible, they are far more hygienic than traditional materials, particularly as Zirconia is far less prone to absorbing bodily fluids, which is the case for any resin hybrids.
The Davis Bridge includes a porcelain veneer which is colour matched to your needs, giving a more natural appearance. This veneer is then layered on the buccal surface of the restoration, leaving all incisal and occlusal surfaces so the teeth are 100% Zirconia in the loading areas. This massively improves the strength of the prosthetic restoration, thus reducing the risk of patients chipping the bridge to virtually zero.
Lastly and importantly, all materials used by Davis Advanced Dental Prosthetics are of course fully TGA registered.
