A universal dental implant structure includes an implant member and a tooth cap. The implant member has an implant portion, an extended holding portion connecting to the implant portion and a coupling cavity located at one side of the extended holding portion remote from the implant portion. The implant portion is anchored in a cancellous bone and a cortical bone. The extended holding portion is extended outside the cortical bone in a range between 3 mm and 6 mm. The tooth cap has a coupling portion to couple on and fasten to the extended holding portion. The dental implant structure of the invention resolves the problem of occlusion interference in the conventional one-piece type dental implant structure and provides the advantage of withstanding high shearing force thereof, and also has the advantage of flexible assembly in the two-piece type dental implant structure through an abutment.
