How Crowns Attach to Dental Implants

Dental Implants

Crowns are usually ceramic porcelain caps that cover broken or discolored teeth, restoring them to an original state. They can be used to protect teeth from further damage or used for dental implants. Dental implant crown restoration refers to the process of a dental implant where the crown is secured to the implant, forming an artificial tooth. Because crowns are 100% customized and durable, they are a long-lasting solution to a brighter smile.

Dental Implants

Dental implants are an excellent long-term solution to replace a missing tooth. Each implant begins with a titanium post that surgically embedded in the jawbone. An abutment then connects to the titanium post and links it to the crown. A crown can be attached to the abutment and post by cement or a screw.

Cementing a Crown

Cemented crowns are ideal for their aesthetically pleasing result. They are commonly used for any teeth visible while smiling.

The downside is that there is a risk the cement may cause inflammation and even bone loss if it interacts badly with the gum and bone tissue. As well, if the implant needs any repairs, cemented crowns for a dental implant crown restoration are challenging to remove. To access the screw that connects the abutment and the post, a dentist may need to drill through the crown and then either cosmetically repair the crown or replace it all together.

Screw-Retained Crown

Choosing a screw for dental implant crown restoration generally has the advantage that it is easier to remove for any needed future repairs. A screw also means there is a lower risk of damage to the implant when repairs or a crown replacement is required.
However, the downside is that the screw option may be less desirable from a cosmetic standpoint. To secure a crown using a screw, the access hole may appear noticeable even after it has been filled in with tooth-colored filling. As well, there is a risk the crown may chip around the access hole.

Making the Best Choice

The choice between cement or a screw to secure a crown in a dental implant will likely depend on factors of where the implant is, whether there is a reaction to the cement or if the dentist has a preference. Though the titanium post will often last a lifetime, a porcelain crown will need repair or replacement at some point due to their use in the mouth over time. At the time of the initial consult for a dental implant crown restoration, options will be discussed to find out which form of attachment will work best. The reality is that the result will be a newer and fresher set of teeth than the ones before.
