Different Types of Dental Crowns for Implant Restoration
If you opt for an implant restoration, the procedure ends when you get the dental crown. The crown is connected to the abutment on top of the implant to make the final restoration look natural. Dental crowns can be created from different materials, including ceramic, porcelain, silver, gold and metal alloys. While ceramic and porcelain give the most natural and aesthetically pleasing appearance, gold crowns are the most durable type of dental crown.
Dental crowns for implants
The material used for making the dental crown is not the only differentiating factor. The method of connecting the crown to the implant also makes a big difference. The two major types of dental crowns for implants are screw-retained and cement-retained crowns. The following section contains basic information about the two types of dental implant crowns.
Screw-retained dental crowns
The screw-retained implant is made of a lingual and occlusal screw. The crown is fabricated with a hole on the lingual or occlusal portion of the dental prosthetic. The hole is used to connect the dental restoration to the implant with a connecting screw attached to the top of the abutment sitting on the implant. This mechanism allows easy removal of the dental crown for restoration, repairs or cleaning.
Cement-retained implant crowns
Cement-retained crowns are connected to the top of the abutment. The dentist will use dental cement to keep the prosthetic tooth permanently connected to the abutment. This dental crown is more aesthetically pleasing and allows secure attachment. Removal is much more difficult compared to screw-retained dental crowns.
Pros and cons of screw-retained and cement-retained crowns
No dental restoration is perfect and these crowns are no exception. For instance, although a screw-retained dental crown can be removed easily for repairs or replacement, the part close to the access hole is vulnerable to chips. The dentist can correct this issue with composite bonding.
Another significant drawback with screw-retained crowns is that the crown can loosen gradually over time. The patient will need to visit the dentist to have them tightened.
The major drawback of cemented crowns is the risk of inflammation if dental cement material seeps onto the gum line. Since removing this type of crown is more challenging, it could cause complications during repair or replacement.
Why choose an implant restoration to replace lost teeth
Although patients can choose other types of dental restorations, such as dentures and bridges, to replace lost teeth, none are as reliable and functional as dental implants. Implants not only restore the feel and function of the lost tooth but also replicate the root to ensure stability and bone preservation. They help minimize the loss of jawbone tissue that is often caused by missing teeth. Other benefits of implant restorations include:
- Serves as a permanent dental solution
- Stops remaining natural teeth from shifting out of place
- Has the same cleaning and maintenance needs as natural teeth
Regardless of the type of dental crown used to cover the dental implant, you can be assured of an excellent dental restoration that looks like natural teeth. To know if you are eligible for an implant restoration, book an appointment with the implant specialist today.
