Abstract:
Accurately recording implant positions and the edentulous areas during the fabrication of implant-retained overdentures can be a difficult task. A modification of the dual or split-tray technique is suggested for implant-retained overdentures. This procedure permits the construction of the prosthesis on one master cast and the use of two impression materials with different properties incorporated into a single impression to correspond with the needs of specific anatomic areas of the mouth.
