Abutment (dentistry)
Abutment (dentistry)
An abutment in dentistry is a connecting element. This is used in the context of a fixed bridge, implant, or removable partial denture to attach to the implant fixture.
Pronunciation
The term 'abutment' is pronounced as /əˈbʌtmənt/.
Etymology
The term 'abutment' originates from the Middle English word 'abuten', which means 'to border upon'. It was first used in the context of dentistry in the 19th century.
Function
The abutment serves as the direct connection between the implant and the overlying prosthesis. It is designed to provide a secure and stable platform for the prosthesis and to distribute the forces of mastication (chewing) evenly across the implant and surrounding bone structure.
Types of Abutments
There are several types of abutments used in dentistry, including:
- Stock Abutments: These are pre-fabricated and come in a variety of shapes and sizes. They are typically made of titanium or zirconia.
- Custom Abutments: These are designed and fabricated specifically for the patient's individual anatomy and needs. They can be made from a variety of materials, including gold, titanium, and zirconia.
- Temporary Abutments: These are used during the healing phase following implant placement. They are typically made of plastic and are replaced with a permanent abutment once healing is complete.
