Removal of Abutments or Crowns

Removal of a Seated Abutment

1. Grasp the abutment and tap on the handle of the grasping instrument away from the implant to release the abutment from the implant.

2. Alternatively, grasp the abutment with a serrated-tipped forcep and use a simultaneous twisting and pulling motion to release the abutment from the implant.


Notes: It is essential to establish a firm grasp or purchase with a serrated-tipped instrument prior to attempting the removal of an abutment.

Tapping on the handle of a serrated grasping instrument is the preferred method, especially for recently osseointegrated implants.

 


Removal of an Integrated Abutment Crown™ or Cemented Crown

1. Grasp the crown and tap on the handle of the grasping instrument away from the implant to release the crown/abutment unit from the implant.
2. Alternatively, grasp the crown with a serrated-tipped forcep and a cotton two by two. Use a simultaneous twisting and pulling motion to release the crown/abutment unit from the implant.


Notes: It is essential to establish a firm grasp or purchase with a serrated-tipped instrument prior to attempting the removal of an abutment.

Care must be taken to cover the restoration surface with gauze to avoid damage.
