The invention discloses a miniature anchorage screw and a correcting device with the same. A circumferential stabilizing groove is formed in a screw rod main body and is arranged in the tail end of the screw rod main body. The circumferential stabilizing groove comprises a first cavity wall, a second cavity wall and a cavity formed by the first cavity wall and the second cavity wall; the surface where the first cavity wall of the circumferential stabilizing groove is located is vertical to the surface where a threaded guide of the screw rod main body is located; the length of the cavity is equal to the distance among 3-4 tooth-shaped bodies, and the depth of the cavity is equal to the height of a tooth; the first cavity wall and the screw rod main body form a rotary cutting angle; and the rotation direction of the rotary cutting angle is opposite to the implanting rotation direction of the screw rod main body. After the anchorage screw is implanted to a gum, a compact bone grows to fill the circumferential stabilizing groove, so that the implanted miniature anchorage screw obtains a resistance surface along the tangential direction of a circumference, and the phenomenon of circumferential rotary displacement of the implanted miniature anchorage screw is avoided. By using the miniature anchorage screw, the circumferential stability of the miniature anchorage screw can be improved, and the condition that the deformity collecting effect is reduced because of harmful release of a traction force is avoided.
