Dental Implant Restoration: The Different Parts of a Dental Implant
Dental implant restoration has been used for several years as a permanent, natural-looking tooth replacement option. When considering dental implants, most people would probably want to know more about the process and the parts that make up the implant restoration. This guide covers the main parts of a dental implant and how they work to create a lasting smile.
Components of a dental implant
Traditional dental implant restoration has three pieces, including the implant post or screw, the abutment that sits over the implant top and the prosthesis or tooth restoration, which might be a crown, bridge or denture. Below is a description of each of the components.
The implant post
The dental implant is a titanium post that is inserted into the jawbone. The implant looks and functions like the natural tooth root, which is the basis of its design. Its end is tapered as with the real tooth root. Implant posts are available in different diameters, depending on the tooth that requires replacement.
For instance, a larger diameter is more appropriate for larger teeth such as a molar, while a narrow diameter implant would be used for a smaller tooth like the incisors. The length of the implant also varies based on the size and position of the lost tooth. An implant post may reach a length of 18mm, and for instance, mini dental implants are often longer for improved strength and stability. A regular dental implant is hollow to allow the attachment of abutments.
The three-piece implant design makes it possible to cover the implant post for the osseointegration process. This means a dental implant restoration will not be attached immediately. The abutment is connected later when the patient is ready to get the dental prosthesis.
Different types of implant abutments are available, depending on the type of implant used for the restoration process. For instance, the abutment that holds crowns and bridges are different compared to those used to support dentures. The type used for crowns and bridges looks like a tiny tooth barely protruding above the gum line.
Abutments used to support a denture are different since the implant dentures can have unique connectors on its surface to clip to the abutment. Alternatively, the abutment may support a bar onto which the denture clips.
The tooth prosthesis could be a crown, bridge or denture. Single tooth implants are meant for dental crowns, while multiple implants are meant for bridges and dentures. The prosthesis is usually connected permanently and can only be removed by a dental professional.
Implant dentures are often removable to allow easy cleaning and maintenance. While in the mouth, the dentures are held firmly and are stronger and more stable, in contrast to traditional dentures that lie on the gums.
Most dental implant restorations are designed to have three components, but it could also come as two-piece units, where the implant and the abutment come as a single component. If you need more answers about how dental implant restoration works, book an appointment with the general dentist.
