Custom impression procedure
When a nice emergence profile has been worked out in the Provisional Restoration, it's useful to carry that over to the final restoration. One technique is shown here. The abutment is removed, an implant analog is attached, then the assemblage is placed down into a small cup containing impression material. When this is set, the abutment is removed and an impression device is attached. Flowable resin or acrylic is placed down into the crevice between the impression material and the impression device. When cured, the retaining screw is unscrewed and the assemblage withdrawn. This "Custom Impression Device" is then able to be placed into the mouth to be picked up in an over-impression.
