Resumen

This article describes an impression technique to transfer implant positions to the definitive cast using magnetic attachments splinted with acrylic resin for an implant-retained orbital prosthesis. The acrylic resin transfer device that incorporated the magnets was also used as the acrylic resin magnet substructure for the silicone orbital prosthesis. (j Prosthet Dent 2008;100:52-55) SUMMARY This article describes an impression technique for an implant-retained orbital prosthesis; in this situation, making the implant impressions in the conventional manner was not possible due to improper implant positioning. An advantage of this technique is that the acrylic resin transfer device that Incorporates magnets is also used as the acrylic resin substructure for the silicone orbital prostheses. A disadvantage of the procedure is the requirement of an additional appointment to make the definitive impression. The effect of acrylic resin polymerization shrinkage is minimized by prefabricating the acrylic resin substructure that is used to splint magnets and corrected at the time that the definitive impression is made.
