Dental Implant Crown – Which is The Best?
What is a Dental Implant Crown ? I heard you asking.
In General, a dental crown is actually a tooth-shaped “cap” that is placed over a tooth — covering the tooth to restore its shape and size, strength, and/or to improve its appearance.
The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.
In the case of dental implants, the crown serve to cover the implants embedded within the jawbone.
What types of dental Implant crowns are available?
Basically there are 4 main types of dental crowns available. They are:
- Metals Crowns:
These types of crowns can be made with gold alloy, palladium alloy and any other metal alloys. They can also be made of base-metal alloy like nickel and chromium. These are very strong crowns that can withstand biting and chewing forces very well. They do not corrode and can last for a very long time. However, the main drawback in using metal crowns is their colors (which just doesn’t match with the natural color of our teeth) and as such they are usually reserved for use only for out-of-sight location within the mouth like where the molars are. Also, the use of nickel base metal crowns may also provoke metal allergy in the mouth of some patients.
2. Porcelain Fused to Metal
The porcelain fused to metal type of crowns is considered a hybrid of other types of crowns. They are basically made up of 2 parts. A base that is made of metal alloy and an upper part that is made of porcelain. Which make sense since the base will be the part that fits onto the tooth and the metal alloy would provide a strong hold while the upper porcelain top would be more natural giving a white tooth-like coloration. As with the use of metal crowns, the porcelain fused to metal may also cause metal allergy in some individuals.
3. All Resin Crowns
All-resin dental crowns are less expensive than other crown types. However, they wear down over time and are more prone to fractures than porcelain-fused-to-metal crowns.
4. All-ceramic or all-porcelain Crowns
The all ceramic or all porcelain dental crowns has the advantage that they resemble the look of our natural tooth and hence are more lifelike as compared to using the porcelain fused to metal dental crowns. One problem with the use of porcelain fused in metal crowns is the appearance of darkness on the tooth especially along the gum lines. But with the use of the all ceramic or all porcelain crowns, this does not happen.
Overall, the all porcelain or all ceramic crowns provide the best natural color match in comparison to all other types of crowns. As there is no metal component in these types of crowns, they are suitable for people who are prone to metal allergies as well. They are the best choice for front teeth crowning.
One drawback though is that these types of crowns are not as strong as the porcelain fused in metal type of crowns and they tend to chip easily as well as wearing down adjacent teeth more than the resin or metal crowns. They also tend to last not as long as the porcelain fused in metal or the metal crowns. At most 15 years.
The cost of a dental implant crown varies widely depending on the type of material used, the location and complexity of the procedure as well as the level of skills required of the dental surgeon. Typically cost of a crown for a tooth cost between $500 to $3000. For all porcelain or the all-ceramic crowns, it cost relatively more as it requires a higher level of skills and longer time as compared to the metal or porcelain fused in metal type of dental implant crown.
