Types of Dental Implant Crowns
A dental implant crown is a restoration that a dentist attaches to an implant. It becomes part of the artificial tooth that sits above the gum line. This new artificial crown is what you will use to chew. It restores the aesthetics of your smile and gives you back your confident grin.
Since a dental implant crown is on the visible portion of your new tooth, it makes sense to learn more about it before you get one.
Different ways dentists categorize dental implant crowns
A dentist will present you with a couple of options for your implant-supported crown. They will walk you through the different types of materials used to make dental crowns. They will also explain the pros and cons of each type of dental crown.
The dentist will also explain the different ways that a dental implant crown attaches to the implant. A patient needs this information to choose a dental crown that is comfortable, durable and pleasant to look at.
Types of dental implant crowns, based on material
There are various types of dental implant crowns. Some are made of metals like gold and others are made of porcelain fused with metal. The most popular crowns are tooth-colored, ceramic crowns. They are loved for their natural appearance, even though they are the least sturdy of the three types.
A patient will choose the type of crown that meets their needs. If the patient wants a crown that can withstand anything, they will choose a metallic or porcelain-and-metal crown. If they want a uniform smile, they will choose the tooth-colored option.
Types of dental implant crowns, based on how they attach to the abutment
Dental labs fabricate dental implant crowns based on the instructions of the dentist that requests said crown. A dentist will request one of two types of crowns:
1. Cement-retained crowns
This type of implant crown is attached to the abutment with dental cement. Dentists and patients alike prefer this type of crown for the following reasons:
- Dentists like this type of crown because it is easy to fabricate
- It is very easy to attach a cement-retained crown to an abutment. There is no need to tighten awkwardly positioned screws
- Patients like this type of crown because it looks very natural. There are no allowances for screws on cement-retained crowns
That said, this type of implant crown has some drawbacks. For starters, the dental cement can sometimes seep into the gums, causing problems like inflammation and bone loss. These crowns are also harder to maintain because you cannot unscrew them if a problem arises. Detaching them from the abutment can be messy.
That is why some dentists prefer crowns that are screwed onto the abutment.
2. Screw-retained implant crowns
As their name suggests, screw-retained crowns attach to abutments with screws. This crown has two allowances for two screws. One hole is on the biting surface of the crown and it allows for the insertion of the occlusal screw. The second hole is on the side of the crown that faces the tongue. It allows for the insertion of the lingual screw. These two screws attach to the abutment and hold the crown firmly in place.
The great thing about screw-retained crowns is that they are easily detachable, which makes maintenance very easy. However, the holes that hold the screw are prone to cracking and chipping, as a result of wear and tear.
