The present invention provides a pedicle screw, which includes a screw head, a screw body, a screw rod and a screw cap. The screw body includes a ball-liked arc-shaped buckle portion and a column-liked thread portion. The screw head includes a semi-sphere part with an arc-shaped dimple on one end and a U-shaped cavity on the other end. The U-shaped cavity connects with the arc-shaped dimple. Furthermore, the Arc-shaped dimple connects with the arc-shaped buckle portion. The Arc-shaped dimple includes an opening on its top to allow the screw body passing through. The U-shaped cavity includes an opening, which includes a female thread to fix the screw rod in the U-shaped cavity by a male thread on the screw cap.

An integrated medical bite block is engaged by a user's teeth and installed into the user's mouth. The bite block includes a through passageway, an upper grove, and a lower grove. The through passageway is penetrating through the bite block. One end of the through passageway comprises an inlet opening, the other end comprises an oral opening. The oral opening is connected with the user's mouth. An upper surface of the bite block provides the upper grove configured for receiving one or more upper teeth (maxillary teeth) of the user, and a lower surface of the bite block provides a lower grove configured for receiving one or more lower teeth (mandibular teeth) of the user. One distance between the lower grove and the oral opening is greater than the other distance between the upper grove and the oral opening, thereby the invention serves to extend forward the mandible and reposition a malposition between the mandible and the maxilla of the user.
