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.
A few years back, when you visited your dentist for getting a crown for your teeth, you would usually be presented with two options. You would have to choose between a gold based crown or a porcelain fused to metal (PFM) crown. İt was not until only a few years back when zirconia based crowns and bridges were introduced into the dental industry and were praised for their excellent strength and esthetics. Now, most dental practices are switching from the conventional PFM and all-ceramic crowns towards the use of zirconia for fabricating fixed dental prostheses.
PMF, Porcelain fused to metal crowns are more affordable than all ceramic crowns. Even though they are not as aesthetic as porcelain crowns they are still a good choice especially for back teeth restoration or those on a budget..
Porcelain fused to metal crowns (or PFM crowns) has a metal layer underlying and porcelain / ceramic on top of it.The metal framework is thin, strong, and perfectly fits the prepared teeth. It’s a combination of different types of alloys which are designed such that they bond very well with the porcelain. Metal alloys with a high melting temperature are used to fuse porcelain to the surface and preventing the metal from melting. This ensures the porcelain to bond without changing its color.
Advantages of metal fused to porcelain crowns
*They are strong and durable
We have been using PFM crowns for more than 35 years. In fact, many are replacing their all porcelain crowns with PFMs these days. The reason being the underlying metal makes your crown stronger and more stable. The metal enhances the bonding to the tooth.
*They look like your natural teeth
You have a variety of shades to choose from to make it look like your other teeth. A unique property of porcelain is, it is translucent, and it helps to mimic your natural teeth. (Translucency is the phenomenon wherein the light partially passes through the object. Your natural teeth have some amount of translucency.)
*They have a very high rate of success in the long run.
*The best part of these crowns is the stability and strength which is unmatched to any other restorations available today.
*These are best for patients looking fora natural look, durability & those on a budget..
*PFM is a preferred choice when bridges for the long run are required and night grinding is a problem.
