Disclosed is a dental device that precisely transfers the location and axial orientation of one or more dental implants in the oral cavity by impression to a laboratory model. The device is a three component assembly of a transfer cuff, a locating sleeve, and a retaining screw that secures to an implant in the mouth. The cuff and locating sleeve engages the anti-rotational feature of the implant. After an impression material has completely surrounded the device secured to an implant, the retaining screw is unscrewed and the internal locating sleeve retracted to such that the connection with the implant anti-rotational feature is disengaged. The impression is then removed from the mouth, retaining the transfer cuff therein, precisely located and accessible for making a stone model thereof for a restoration construct for securing to the implant. The universal transfer device and impression method of the invention precisely transfer locations of multiple implants and their anti-rotational features, even where the implants are not in parallel axial alignment. <IMAGE> |
