The Difference Between Healing Abutment And Covering Screw

Covering screws: Covering screws are for the implantation method that requires second-stage surgery for dental implants

The first-stage operation is to install a covering screw after the implant is placed in the alveolar bone and temporarily seal it to prevent bacteria, soft and hard tissues from growing in.

Healing abutment (temporary abutment): After the implant + covering screw is implanted in the alveolar bone, it is necessary to wait three months for the fusion with the alveolar bone tissue, and the second-stage operation will begin three months later.

In the second stage operation, the cover screw is replaced with the healing abutment, and the head end of the implant is temporarily docked (this time takes 1-2 weeks), in order to promote the formation of the gingival cuff, form the gingival sulcus and protect the interdental papilla, for the later stage Abutment restoration provides space for space.
