The invention relates to the field of oral cavity medical devices, and discloses a dental implant abutment locator and a 3D printing manufacturing method and impression taking method thereof. The dental implant abutment locator disclosed by the invention comprises an in-place body, a reset body and a connecting body which are integrally connected, wherein the gum end of the in-place body is provided with an abutment positioning cavity being adaptive with a dental implant abutment, and an abutment screw hole communicates with the abutment positioning cavity, and extends and penetrates through the cutting end of the in-place body; the reset body adopts the structure shape which covers and is adaptive with an abutment surface or/and the cutting end; and gaps are reserved between the in-placebody and adjacent teeth and gum. The reset body and the abutment surface or/and the cutting end of the dental implant abutment located are in cooperation to realize positioning, and besides, certain gaps are reserved between the in-place body and the adjacent teeth, so that the in-place body can smoothly and accurately reach the designated position without extrusion, accurate positioning and mounting of the dental implant abutment can be guaranteed, and a favorable foundation is provided for subsequent treatment and rehabilitation.
