Dental crowns are a common dental restoration used to cover and protect a damaged or decayed tooth. They are typically made of porcelain or ceramic and are designed to fit over the top of a tooth, mimicking its natural shape and color. This blog post aims to explore the differences between two types of dental crowns: screw-retained and cemented crowns.
Screw-Retained Crowns
A screw-retained crown is a type of dental crown anchored by a small screw. This screw is placed into the tooth, and the crown is then attached to the screw. Screw-retained crowns are typically used when the tooth being restored is missing or has limited tooth structure remaining.
The placement of a screw-retained crown is more complex than a cemented crown. A small post, called an abutment, is first placed into the tooth. The abutment is then used to hold the screw in place. Once the screw is in place, the dental lab will create the crown to fit over the abutment and screw. The crown is then placed over the abutment and secured in place with the screw.
One of the main advantages of screw-retained crowns is that they offer excellent retention. Because the crown is anchored with a screw, it is less likely to come loose or fall off. Additionally, screw-retained crowns are easy to access for cleaning and maintenance. This is because the abutment and screw are exposed, doing cleaning and maintaining the area around them easy. Screw-retained crowns also have good longevity.
However, screw-retained crowns do have some disadvantages. One of the main disadvantages is that the placement process is more complex than a cemented crown. This can make the procedure more time-consuming and can also increase the cost.
Cemented Crowns
A cemented crown, also known as
a traditional crown, is a type of dental crown secured with dental cement. The
crown is placed over the tooth and then cemented in place. Cemented crowns are
typically used in situations where the tooth being restored has enough tooth
structure remaining to support the crown.
The placement of a cemented
crown is relatively simple. The dentist will first prepare the tooth by
removing any damaged or decayed tissue. They will then take an impression of
the tooth, which will be used to create the crown. Once the crown is complete,
the dentist will place it over the prepared tooth and secure it with dental
cement.
One of the main advantages of
cemented crowns is that they are a simpler and more cost-effective option than
screw-retained crowns. Additionally, cemented crowns are also more esthetic.
They have better color and clarity, matching natural teeth.
However, cemented crowns do have
some disadvantages. One of the main disadvantages is that they can have
retention issues. Because the crown is only secured in place with dental
cement, it is more likely to come loose or fall off. Additionally, cemented
crowns can be difficult to access for cleaning and maintenance.
Comparison of Screw-Retained and Cemented Crowns
When comparing screw-retained
and cemented crowns, there are a few key differences. One of the main
differences is retention. As mentioned earlier, screw-retained crowns offer
excellent retention because they are anchored in place with a screw. Cemented
crowns, on the other hand, can have retention issues because they are only
secured in place with dental cement.
Another key difference is the
placement process. As discussed earlier, the placement process for
screw-retained crowns is more complex than for cemented crowns. This can make
the procedure more time-consuming and can also increase the cost.
Maintenance and cleaning are
other important considerations when comparing the two types of crowns.
Screw-retained crowns are easier to access for cleaning and maintenance because
the abutment and screw are exposed. Cemented crowns, on the other hand, can be
more difficult to access for cleaning and maintenance because they are fully
covered by the crown.
Finally, the cost is another
factor when comparing screw-retained and cemented crowns. Screw-retained crowns
are more expensive than cemented crowns due to the more complex placement
process.
Conclusion
In conclusion, screw-retained
and cemented crowns effectively restore damaged or decayed teeth. However,
there are some key differences when choosing between the two. Screw-retained
crowns offer excellent retention and are easy to access for cleaning and
maintenance, but they can be more expensive. Cemented crowns are a simpler and
more cost-effective option, but they can have retention issues and be more
difficult to access for cleaning and maintenance. Ultimately, the best option
for you will depend on your individual needs and the specific circumstances of
your case.
