Dental crowns or caps are tooth-shaped, natural in appearance covers that are placed over a weakened, decayed, chipped, broken, damaged or a root canal treated tooth as far as the gum to strengthen & restore the natural appearance & prevent further deterioration of a tooth.
Crowns are also becoming an increasingly popular choice to improve the overall appearance, shape & alignment of a smile Crowns can be made to resemble the tooth in its original form, in shape and colour, so that the look is seamless and often a better appearance can be achieved.
The great benefit to porcelain crowns is they can not only replicate the original tooth in function, but can be designed to look like the original or even better. When patients select a porcelain veneer for cosmetic reasons, they’re usually covering up the front portion of the tooth that has some aesthetic flaw. A porcelain crown is thicker than a veneer and, in some situations, this thickness is needed.
Some of the reasons why we need crowns;
- To give an improved, natural & healthier smile
- Protect and strengthen weak tooth
- Cover a poorly shaped or discoloured tooth
- Cover a tooth that has had a root canal treatment
- Close gaps in between teeth
- Protect tooth from further decay, infection & cracking
- İmprove chewing & talking
- Long term durability.
- To make an aesthetic improvement to change the shape / lengthen / alignment / colour
A bridge, similar to a crown & may be recommended if you’re missing one or more teeth. Gaps left by missing teeth eventually cause the adjacent teeth to drift into the empty space resulting in a bad bite. A dental bridges consists of an artifical tooth connected to a set of crowns used to fill a gap created by one or more missing teeth. Missing teeth can also affect the function of the mouth, the gaps and missing teeth often making it difficult to chew. Bridges span the space where there are missing teeth. Like crowns, bridges are designed to fit within the aesthetic of the rest of the mouth, matching in colour and shape.
Zirconium is fast becoming one of the most chosen materials for dental crowns they are the strongest, they are extremely durable and 100% biocompatible, Zirconia is also used for various prosthesis in surgeries of hip, finger and ear.
Advantages of Having Zirconium Crown
*Superior looks: as zirconia is white naturally, it allows the new crowns to match with the rest of your teeth, the translucency mimics that of your own natural teeth
*More confident smile: Previously porcelain fused to metal crowns were popular earlier, however the metal layer underneath the porcelain layer which is on top of the crown becomes visableusually at the gum line over time. This is more evident when you smile. Zirconia crowns help you get over this and boost your confidence. Zirconium crowns also can be proc-duced in any shape/ size to match the rest of your teeth.
*100% biocompatible: no zirconia crown allergy is reported so far.
*Extraordinarily tough: zirconia is the strongest crown, it can withstand wear & tear. It does not chip off, unlike porcelain. If you maintain it well, it can stay in your mouth forever. It is at least five times stronger than porcelain or porcelain fused to metal/ PFM. It also tolerates chewing or biting forces well. It has a very high flexural strength
*They bond well with your tooth: zirconia crowns adhere well to your tooth. One of the reasons why PFM crowns were the preferred choice is that the metal surface bonds well with the tooth and holds the crown in place. Zirconia also has this property.
*These crowns require less tooth removal than many other types of dental crowns.
Metal free: many people used to prefer gold crowns because of their excellent physical properties however sinceappearances are more important to people nowadays, they want to look natural and young, zirconium fulfills this desire.Some people also don’t like having metals in their body. Zirconia is most suited for them.
*The aesthetic effects alone of a zirconia crown should be the biggest advantage it can give. It is important that you have dental crowns that will look natural especially if it will be placed at the front teeth and will be visible beside the natural teeth.
*Zirconium crown not only replacs a tooth but it can be shaped so that it will look better than the one it will be replacing.
Advantages of Zirconium Crowns over Gold Crowns and Porcelain Crowns
It is a fact that gold crowns have been used by many people for so many years and it is well tolerated by the body. But it is still better to be able to show that natural effect when you smile. Add the fact that gold is metal and some people just do not like having metals in their internal parts.
Zirconium crowns are definitely more robust than porcelain crowns. They last longer too, compared to porcelain that chip and break.
Porcelain crowns also need to be fused to a metal base and the metal is that black unsightly line above the gums of people with porcelain crowns.
Since Zirconium crowns are milled from a chunk of crystal, they are guaranteed to be at least 5 times stronger than porcelain and it metal fuse. Zirconium crowns also provide strength without that bulky appearance that porcelain is so known for.
