The present invention relates to the field of medical titanium alloy materials, and in particular, to a narrow-diameter high-strength implant-specific medical titanium alloy achieving immediate implant placement and a preparation method for the implant-specific medical titanium alloy. The medical titanium alloy is prepared from the following chemical components (by weight percentage), 14%-17% of Zr, 3.0%-10% of Cu, and the balance of Ti. The preparation method for the medical titanium alloy comprises: after cogging and forging and before rolling, performing heat preservation for 0.5-6 h at the temperature of 900-1200° C., and water cooling to the room temperature; and rolling at the temperature of 720-850° C., a strain rate being larger than 0.1 s−1, and a barstock obtained after rolling being used for subsequent implant processing. According to the narrow-diameter high-strength implant-specific medical titanium alloy achieving immediate implant placement provided in the present invention, immediate implant placement can be achieved without any surface treatment, and a firm combination of the implant and a bone tissue is achieved. According to the preparation method for the medical titanium alloy provided in the present invention, the implant having a narrow diameter (3.0-3.5 mm) can be prepared and is high in strength, and the purpose of firm implanting on a narrow teethridge missing a tooth is achieved.
