Abstract:
Achieving an accurate final impression is the initial step in the fabrication of the definitive restoration. If polyether is to be utilized for the final impression, obtaining an additional impression may minimize the risk of fractured abutments. In addition, transportation conditions to the dental laboratory that may expose the impression to extreme temperatures should necessitate the pouring of the impression prior to shipping.
