A laboratory attachment jig is described for use in accurately positioning an attachment relative to an implant abutment/fixture analog of a working model. This jig comprises an orientation arm having a first end and a second end, the orientation arm including a fastener for securing the orientation arm to the abutment/fixture analog of the working model. A primary support member is attached to the second end of the orientation arm, with the primary support member and the orientation arm being supported transversely in a first plane. The primary support member includes a vertical positioning sleeve and a fastener for the vertical positioning sleeve. A lateral support arm is attached to the vertical positioning sleeve of the primary support member and includes an end. A mandrel support member is attached to the end of the lateral support member for retaining the attachment. The lateral support arm includes a lateral positioning sleeve and a fastener for the lateral positioning sleeve. In use, the lateral support arm is adapted to be movable up or down on the primary support member upon loosening of the fastener for the vertical positioning sleeve and is adapted to be movable forward or backward relative to the primary support member upon loosening of the fastener for the lateral positioning sleeve.
