transfer impression
An impression taken to record and transfer the precise three-dimensional position of implant components, teeth, or prosthetic elements from the patient's mouth to the laboratory.
Full Definition
A transfer impression captures the exact spatial relationship of implant analogs, abutments, or natural teeth so that laboratory technicians can fabricate accurate prostheses on a master cast. Two main techniques exist: the open-tray (pick-up) and closed-tray (repositioning) methods. Editors working with implant case documentation, clinical reports, or laboratory work orders will encounter this term frequently. It should not be confused with a 'bite registration' (which records occlusal relationships) or a 'diagnostic impression' (taken for study models).
Usage
Usage note: Specify whether the open-tray or closed-tray method was used when editing clinical or laboratory reports, as this affects procedural documentation accuracy.
