Fig. 1 Fixture Mount/Transfer Fig. 2 The two-piece, 15º Angled Abutment consists of an angled body and a fixation screw To establish the optimum angle of the abutment, index the flat surface of the Fixture Mount/Transfer either toward or away from the desired direction of abutment angle at the time of implant placement. Option 1 :- Attaching an Angled Abutment and chairside procedures for preparation Remove the Healing Collar with a 1.25mmD Hex Tool Attach the abutment with the 1.25mmD Hex Tool Mark the required modifications to achieve appropriate clearance Detach the abutment with the 1.25mmD Hex Tool Attach the abutment to the corresponding Implant Analog Reduce the abutment to achieve appropriate clearance Option 2 :- Stage-One transfer followed by laboratory procedures for abutment preparation and provisionalization During implant placement, index the flat of the Fixture-Mount With Fixture-Mount in place make a conventional transfer impression Attach the Cover Screw and submerge implant The Fixture-Mount is retained within the impression material when it is removed Pour the working cast in dental stone with soft tissue replication material Remove the impression from the working cast exposing top of Implant Analog Attach the Angled Abutment to the Implant Analog in the working cast with a 1.25mmD Hex Tool Modify angle of abutment and refine margins as required Fabricate the temporary crown At Stage-2 Surgery, Attach the prepared abutment, tighten to 30 Ncm with a Torque Wrench Occlude screw access hole and confirm contour of restoration Cement the provisional restoration Common procedures for abutment placement, margin finessing, impressing and placement of restoration Tighten to 30 Ncm with a Torque Wrench Finesse the margins with a highspeed bur and copious irrigation prior to final impressing Make an impression following standard clinical procedures Attach provisional restoration and cement onto the prepared abutment Follow standard laboratory procedures, fabricate the final restoration and cement onto the prepared abutment 4
