Toronto Bridge or Hybrid Bridge is a circular bridge of 12 or 14 teeth placed exclusively on implants. The bridge is used only in toothless jaw when the bone structure allows implant insertion. It can be made of metal ceramics cam/cad zirconia ceramics or composite. The advantage of this bridge is that supporting elements have tiny holes allowing a dentist to remove the bridge by unscrewing it after certain period in order to clean it and then to reattach it in the same position.
