See: Orientation jig
An orientation jig is a device that is created in the laboratory. This abutment transfer device is designed to correctly maintain a component’s positional relationship as it is transferred from the custom-designed cast to the patient’s mouth. Abutment transfer devices are available for use with both closed tray and open tray techniques.
A restorative dentist uses impression coping (i.e., transfer coping) to create a cast that is identical to the patient’s mouth. This cast is used to ensure that the correct position of the patient’s abutment or implant is attained at the time that it is placed. Although impression coping is appropriate for the creation of an abutment level or an implant level cast, the correct coping must be used in each circumstance (e.g., impression posts, transfer copings, etc.).
