Posts for tag: metal free crowns

Do you have an unsightly crown where metal is showing by the gumline? 

Does your gumline appear purple or gray?

Do you have an old gold crown or a porcelain crown that is chipped with metal showing?

Do you have a history of breaking teeth and/or crowns or have a habit of grinding/clenching your teeth?

     If the answer is yes than the Brux-Zir crown is for you! The Brux zir crown is a porcelain-like crown that has the appearance of a metal free crown yet has the strength of a gold or metal crown. They are prepared fairly similar to traditional crowns except the material is virtually unbreakable and scratch proof. They are more unique in that they are often times fabricated by a computer giving excellent precision and long term stability.

Question: What are the pros and cons of metal free crowns?

Answer: Metal free crowns are a great alternative to the more traditional gold crowns and porcelain fused to metal crowns we have seen over the past 20 years. The reason is due to the esthetics as there is no metal in the crown and no darkening of the tooth can occur. Color matches tend to be better and also are typically more stable since they are made of 1 material versus multiple materials. Many patients with porcelain fused to metal crowns(aka PFM crowns) will see a gray line at the gumline over time as the gum recedes or pulls away from the tooth. This can lead to very unsightly esthetics over time. Even if the gum does recede, a metal free crown will not yield a gray line because their is no metal present. Although esthetics are exceptional, there are limitations on where they can be placed such as the bite. Patients that have a "tight" or "deep" bite may not have sufficient room for these type of crowns. If the crowns are placed anyways, they are more susceptible to fracture. Metal free crowns are more at risk for fracture if the patient is a severe grinder or clenches their teeth often. Talk to Dr. Glasmeier about metal free crowns!

 

Question: What is a bridge?

 

Answer: A bridge is a permanent dental restoration that replaces one or more teeth. It is permanent in that it is permanently glued in and cannot be taken in and out of the mouth like a denture. It often follows after a hopeless tooth has been extracted(removed). To put in a bridge, I have to prepare and reshape the teeth on both sides of the missing tooth. The bridge consists of the replacement tooth and two crowns (caps) on each side. The crowns will fit over the prepared teeth to support the replacement tooth. This typically requires two appointments and you will be placed in temporaries at the end of the first appointment until the lab fabricates your bridge. While this is one way to replace missing teeth, there are other ways to replace missing teeth such as removable partial dentures and implants.

Question:

 

Hello.I have cerebral palsy.I have a few metal crowns.over time my bite has become off and I ground at night.I didn't take care off this right away like I should have and now my teeth are severely worn.Do you think if I got posts and metal crowns they would last in my mouth?the few crowns I have seem to have done well over time.would the new zirconia crowns be as durable as the metal? Thank you for your time and consideration. Kurt

Answer:

 

Hi Kurt,

 

This unfortunately is a very loaded question that I cannot give you a good answer for the following reasons:

1. Posts do not make teeth stronger...they more less help hold in the foundations that the crowns sit on so they are more for retention, not strength.

2. There are crowns with different properties for different situations, so it is hard to say what is best for you as there many things that need to be evaluated such as:
1. Cavities present?
2. What kind of bite do you have?
3. Condition of existing crowns?
4. How heavy you grind?

These are several questions that would need to be answered before telling you what kind of crowns you need. Having said that, zirconia crowns are showing promise in strength and certainly have esthetic advantages over metal crowns but they are not indicated in all situations. I would recommend getting evaluated to further determine this.

 

Good luck!
