Disclosed is a dental implant with a first internal thread and a second internal thread, comprising a fixed part and a connecting part. The fixed part has an external threading region. The connecting part has an opening, and the opening has a first inner wall and a second inner wall set below the first internal wall. The second inner wall has a first internal thread and a second internal thread, and the directions of the first internal thread and the second internal thread are different so as to coordinate with at least one conveying means respectively, to implant or take out the dental implant. The dental implant is easy to operate, and can be combined with the conveying means without separating from or falling off of the conveying means during clinical operations, and thus contamination of the dental implant after falling off can be avoided.
