A dental instrument for treatment of malocclusion, comprising a shell-like body (105). The shell-like body (105) is provided, at a position corresponding to a posterior teeth region, with a protruding portion (102) that protrudes toward an opposite jaw to align mandibular incisors and maxillary incisors. A part of an occlusal surface of the protruding portion (102) is provided with a friction portion (103) that increases the stability of contact between the upper and lower jaws during occlusal reconstruction. The corresponding posterior teeth region of the shell-like body (105) is further provided with at least one retention portion (2) that fastens to a retention accessory arranged on a tooth corresponding to the posterior teeth region. An anterior teeth region of the shell-like body (105) corresponding to a labial side having an outer surface in contact with teeth is further provided with at least one traction portion (3) for jawbone orthopedic reshaping.
