What does “Implant abutment” mean?
An implant abutment is a connector that joins the implant body to a prosthesis, such as a crown, and supports that prosthesis.
Connecting the body in bone to the tooth-shaped prosthesis
In a typical two-piece implant, the abutment connects to the fixture and passes through the gum to support the prosthesis. Connecting screws and prosthesis fixation vary by system and design. Not all abutments are interchangeable.
Shape suited to position and gums
Abutment height, angle, shape, and material are selected according to placement depth and direction, gum height, and where the prosthesis should emerge. A smooth continuation of prosthetic contours and space for cleaning are also considered.
The final abutment versus a healing component
A healing abutment is a temporary component that shapes the gums during healing and has a different role from the final prosthetic abutment. A loose abutment or screw can lead to connector damage beyond discomfort, so it needs assessment.
Frequently Asked Questions
Is the abutment the artificial tooth?
It is the connector supporting the tooth-shaped crown used for chewing. Both form part of the prosthetic assembly, but they are not the same component.
How do stock and custom abutments differ?
Stock abutments are selected from predetermined specifications; custom abutments are made for the individual implant position and gum and prosthesis contours. Choice depends on the shape and maintenance conditions needed.
