An orthodontic structure includes a body where at least one connecting hole is formed, a fastening part disposed on the body and fastened to an implant, and at least one traction assembly connected to the body. The traction assembly includes an orthodontic table and an adjustment part extending outwards from the orthodontic table to engage the connecting hole. The orthodontic table has at least one locking recess capable of holding a metal wire in place. The orthodontic structure is connected to the implant which is embedded in an alveolar bone in advance to provide a requisite anchorage effect required by orthodontics. Thus, the implant treatment and the orthodontic treatment can be concurrently executed to shorten the treatment time for straightening teeth and attain good implanting and straightening effects.
