It depends on the height and taper of the abutment. As the resistance and retention form of the implant abutment increases the greater the need for increasing the percentage of the abutment surface that must be lubricated. Prior to cementation coat at least 50% of the coronal portion of the implant abutment head with lubricant. In some cases, up to 75% of the abutment surface may
require lubrication for the restoration to be removed successfully. When lubricating an abutment, begin at the occlusal/incisal surface and apply the chosen lubricant down the walls of the abutment to the appropriate level. To create a tight marginal seal, do not lubricate the margins. This should give good retention, while allowing removal of the prosthesis later.
