A placement jig for locating a dental implant analog in a physical model of a patient's mouth includes a base, a guide-strut receiving feature, a throughbore, and an angled receiving feature. The guide-strut receiving feature is positioned within the base and is configured to receive a guide-strut of the physical model thereby positioning a lower surface of the placement jig at a desired distance from an opening of a bore in the physical model. The throughbore receives a screw therethrough that engages the dental implant analog such that the dental implant analog, is removably coupled to the base. The angled receiving, feature is positioned about the throughbore on the lower surface of the base. The angled receiving feature includes a mating surface that is configured to abut a custom abutment positioned between the mating surface and the dental implant analog. |

1. A method of locating a dental implant analog in a model of a patient's mouth for use in creating a tooth prosthesis, comprising:
scanning at least a portion of the patient's mouth to generate scan data, the scanned portion of the patient's mouth including teeth and an attachment member, the attachment member including at least one informational marker indicating the location of a dental implant installed in the patient's mouth; creating a three-dimensional computer model of at least a portion of the patient's mouth using the scan data, the three-dimensional computer model including (i) virtual teeth that correspond with the teeth in the patient's mouth, (ii) a virtual bore at a position based on the at least one informational marker, and (iii) at least one virtual guide strut positioned adjacent to the virtual teeth and spaced from the virtual bore; and fabricating, using a fabrication machine, a physical model of the at least a portion of the patient's mouth based on the three-dimensional computer model, the physical model including (i) a bore corresponding to the virtual bore, and (ii) at least one guide strut corresponding to the at least one virtual guide strut, the at least one guide strut to be used in positioning the dental implant analog within the bore of the physical model at a position and an orientation corresponding to the location and the orientation of the dental implant in the patient's mouth. |
