title: The O-ring universal impression technique.
abstract: Recording the implant position for master cast fabrication for multiple implant systems may require a large inventory of impression copings. A technique is described whereby implant impression-making procedures can be modified to be more universal to all implant systems. This makes the procedure more cost-effective by simply incorporating the use of a rubber O-ring on the abutment or fixture mount, which then eliminates the use of a transfer coping. This technique can be applied at the time of surgery for indexing as well as during the final impression appointment.
