Q. Show the Seating the abutment?

The clinician will need to ensure that the abutment is completely seated.A radiograph may be required to confirm complete seating. Abutments using a tapered connection can be tested by simply applying finger pressure to engage the taper. If the taper does not engage, some obstruction - such as soft or hard tissues may be present and will need to be removed prior to tightening. The fixation screw for the abutment can be tightened to the desired torque, which may vary from 15 to more than 32 N cm, depending on the type of connection.

The access hole for the fixation screw should then be blocked. The ideal method is to use soft wax to cover the screw, following by glass ionomer cement to seal the access hole of the abutment. This will eliminate the undercut to facilitate the relining or construction of a provisional restoration.
