Featured Porcelain Fused to Metal

Nickel Base Alloy

Nickel Base Alloy

Nickel base alloy is the most cost-effective material for metal coping. However, a lot of people are allergic to this material. So they will have to pick other materials. In many European countries, it is even banned in dentistry.

Cobalt-Chromium Alloy

Cobalt-Chromium Alloy

Cobalt-chromium alloy is slightly more expensive but much better than Nickel-chromium. So far, cobalt-chromium alloy is allowed to use in dentistry throughout the world. Yet, there are still people who are allergic to the cobalt-chromium alloy, so they will have to choose other materials.

Semi-precious or High Noble Alloy

Semi-precious or High Noble Alloy

A semi-precious crown contains a small percentage of gold in the metal coping, while a high noble case contains a high percentage of gold. The biggest advantage is that it is basically allergy-free. In other words, it has good biocompatibility.

Porcelain Fused to Metal – Definitive Guide

Metal Porcelain Crown (Porcelain Porcelain Crown) is a metal crown in which a layer of porcelain is welded to metal. This makes them almost as durable as pure metal crowns, but more beautiful. For a long time, porcelain crowns have been the most popular crowns in the dental industry. It is still in use, but ceramic crowns are now the first choice, especially for incisor restorations. Porcelain crowns are more affordable than all-ceramic crowns. Even if they are not as beautiful as porcelain crowns, they are still good candidates for posterior restorations.

1. Advantages of porcelain crown

At present, a porcelain crown is still a very common denture type, here are the main reasons why people like to choose porcelain crowns.

Porcelain crown sturdy and durable

Dentists have used porcelain crowns for more than 35 years. Although all-ceramic crowns have better aesthetics, PFM crowns are still used, although they are not as popular as before. The reason why porcelain crowns are still preferred is that the underlying metal makes the crown stronger and more stable. The metal enhances the bond with the teeth.

They look like your natural teeth

You have a variety of colours to choose from to make it look like your natural teeth. The unique property of porcelain is translucent, which helps imitate your natural teeth. (Translucency is the phenomenon of light partially passing through an object. Your natural teeth have a certain degree of translucency.)

The high success rate in the long run

The best part of these crowns is the stability and strength, which is unmatched by any other repair available today. This is best for patients looking for a natural appearance and durability. PFM is a preferred choice when bridges need a long-term operation and night grinding is a problem. These crowns are not only trusted by patients, but also by doctors around the world.

2. Disadvantages of Porcelain Fused to Metal

What problems you may meet if you choose porcelain fused to metal for your denture? Here are some common problem you can concern.

You will lose a lot of tooth structure

Natural is always best-the more natural the structure of your teeth in your mouth, the healthier your mouth will be. Since PFMs have a metal base underneath, your dentist will need to trim most of your teeth to fit them. However, if you choose to use a gold base under the porcelain teeth, your dentist can save you more teeth.

May cause gingivitis

Porcelain crowns are more likely to increase the chance of gingivitis than other crowns. However, the gold base is good for gums because your body can withstand it. Gingivitis is inflammation of the gums. Redness, swelling, pain, and bleeding are symptoms of gingivitis. )

May hurt your opposing teeth

When you chew, your teeth are in your jaws and will touch. In the long run, porcelain will wear out each other’s teeth.

They won’t give you a perfect smile

The porcelain crown restores your appearance, but other crowns, such as all-ceramic crowns, give you a better smile. After a period of time, the gum line of the porcelain crown will darken. When you smile, a grey line will appear. This is even more true when your gums begin to shrink due to ageing.

PFMs are not suitable for people with receding gums or those whose gums move closer to the bone. The latest technology allows your dentist to choose porcelain butt edges. This ensures that even if the gums recede, you will not see the black gum line.

May be fall off

When you bite hard food, the porcelain on the porcelain crown will fall off.

Higher cost

These crowns can be expensive, especially when the metal you choose is a combination of precious metals.

However, the quality of precious metals is better. Since these crowns stay in your mouth longer, they are beneficial in the long run.

3. How much does a metal porcelain crown cost?

In the United States, the price of a porcelain crown is approximately between US$1,000 and US$1,500.

However, in the case of ceramic fused metal crowns, another reason for the price difference is that the metal is in the crown. The metal can be a noble metal (usually gold), but it can also be an inexpensive base metal alloy, such as silver, cobalt-chromium alloy or nickel.

Your best choice is to buy a gold crown. This is considered the highest quality, although it is the most expensive option. As always, the price will vary greatly depending on your location, the size of the crown, and the experience of the dentist. It is also good to know that cheap crowns containing nickel may cause allergic reactions in some people.

When comparing quotes from multiple clinics, it is best to ask them what metal they use. This is an easily beatable price, an alloy based on the fusion of porcelain crowns and ceramics. You may also want to ask whether this clinic uses a local dental laboratory or imported crowns from China. The following is a rough estimate of the price of porcelain crowns in different countries:

  • U.S.: 1000-1500 USD
  • UK: 400-500 GBP
  • Canada: 1000-1200 USD
  • Australia: US$1100 to US$1300

4. How to fuse porcelain to the metal crown?

Porcelain fused metal crowns (or PFM crowns) can be called full cast crowns, in which porcelain is fused to most or all of the metal cores of the crown. They are a mixture of porcelain crowns and metal crowns. Under the entire canopy is a metal layer, and on the top is a ceramic layer.

The metal frame is very thin, very strong, and very suitable for prepared teeth. It is a combination of different kinds of alloys so that they can be combined with porcelain well. Metal alloys with high melting temperatures are used to fuse porcelain to the surface to prevent the metal from melting. This ensures that the ceramic adheres without changing its colour.

A layer of porcelain melts on the metal shell. Depending on the tooth, the thickness of the porcelain layer is between 1.5 mm and 2 mm. The porcelain layer is hard, can withstand the chewing force well, and looks like your natural teeth.

Also, as a result of this, the majority of the tooth tissue must be removed in order to provide room for porcelain and metal.

5. Types of porcelain fused to metal crowns

The metal frame is a combination of different types of metal. The type of metal is one of the factors that determine the price and quality of your metal porcelain crown.

1) Porcelain fused with base metal alloy

As the name suggests, this frame uses a combination of base metals popular in dentistry. However, some of you may be allergic to some basic metals such as nickel. Choosing a precious metal crown can help you avoid allergic reactions.

2) Porcelain fused with titanium alloy

Titanium alloy has the characteristics of precious metals such as gold. Because of their superior performance, they are useful for implants and other dental restorations. The fusion of ceramics and titanium alloys has better properties than base metal alloys, while gold alloys have better properties.

Porcelain fused with gold alloy

The gold alloy has the best performance, has the highest strength and durability, and does not cause allergies. Although the name says gold, gold alloys are composed of gold, platinum, silver, palladium, copper and tin. A gold alloy contains four precious metals, which are known for their superior properties. The last two metals are called base metals.

The higher the content of precious metals in the gold alloy, the higher the price and the better the performance. Generally speaking, gold alloys for dentistry contain 16k gold. Therefore, gold restorations for dentistry also have resale value. The composition of the gold alloy varies depending on the application.

Metal porcelain crowns, gold inlays, and gold crowns/bridges carry different compositions according to the required properties.

  • If a gold alloy is used under the porcelain layer, in most cases, gold accounts for 40% of the crown, other precious metals such as platinum, silver, and palladium account for 20%, and base metals account for 40% of the crown. We call this kind of porcelain crowns as noble metal porcelain crowns.
  • Sometimes there may be more than 25% precious metals in your crown, and the rest are base metals. We call this kind of porcelain a precious metal crown.
  • The base metal crown may also contain some precious metals.

Gold will not be corroded, will not cause allergies, will bond well with your teeth, and will last longer. One of the main advantages of the gold base is that it can make a thinner crown, which helps to protect the natural structure of the tooth. Thickness does not determine the strength of gold.

You can skip the black gum line if you use gold alloy for the PFM crown.

6. Captek: a high-quality porcelain golden crown

In the past few years, great progress has been made in the field of the fusion of metal crown porcelain. The crowns of patients with all-ceramic crowns are replaced with this kind of crown. The latest Captek dental crown also eliminates the black line visible around the patient’s gumline.

7. What is the procedure like?

The preparation method of metal porcelain crowns is similar to other porcelain crowns. Your dentist examines your mouth, gives you anaesthesia, prepares your teeth, makes impressions, and designs crowns.

Your dentist makes sure that the porcelain pieces are welded to the metal, and the metal is melted at a higher temperature to make the porcelain crown; therefore, when you have hot or very hot food, the porcelain crown will not melt in your mouth Or replace their accessories.

This characteristic of the metal used to make the crown also ensures that when we fuse it with the metal when making the porcelain crown, the porcelain can maintain its natural colour.

The porcelain layer has changed, it can be:

  • Full veneer: cover all surfaces of teeth or teeth
  • Partial veneer: only covers the front surface or visible surface of the tooth. Here, the rest of the tooth surface is metal.

8. How to maintain the crown?

Do not use crowns to bite foods that are too hard. The porcelain layer may peel off. No matter how good porcelain teeth are, they are not as good as your natural teeth. Remember to brush your teeth twice a day and floss your tongue every day to maintain oral health.

9. Porcelain Fused to Metal FAQ

1) Are the porcelain and metal crown fused?

For many years, porcelain crowns have always been people’s first choice, and in recent years, all-ceramic crowns have become more and more popular. Ceramic crowns require less tooth reduction, are more aesthetically pleasing, and support better oral hygiene. In some cases, porcelain crowns are still a good choice. If your dentist advises you to use porcelain and metal crowns, then do it. Just make sure to use noble metals.

2) Does the porcelain fused to the metal crown contain mercury?

Unlike fillings, crowns do not contain mercury. However, base metals like nickel can still cause allergic reactions. Precious metals such as gold and palladium have high biocompatibility and will not cause such problems. You can either choose a metal-free ceramic repair or use noble metal if you are concerned about the metal in the metal porcelain crown.

3) How long can the porcelain and metal crowns last after they are fused?

A good dental laboratory can manufacture a dental porcelain crown that lasts for decades while maintaining good oral hygiene.

Two common problems with porcelain crowns:

  • Porcelain peeling: This is usually caused by eating too hard food and unsatisfactory laboratory work
  • Black lines on the gum line: This may be caused by low-quality laboratory work or gum recession
