There are two types of abutments:
- Cover screw: it is buried under the gum which is then closed by stitches after its attachment to the implant. This type of abutment must be exposed by making an incision in the gum during the prosthetic restoration stage.
- Healing abutment: it passes through the mucosa, and the surrounding mucosa is adapted around it. No further surgery will be necessary to expose the abutment during the prosthetic restoration stage.
Thereafter, a period of time is required for complete healing of the gums before proceeding to the subsequent step.
