Abstract: An orthodontic appliance debonder for minimizing the time and effort on the part of the clinician in removing bondable orthodontic appliances, i.e. those having a plastic body secured to the crowns of the teeth by an orthodontic bonding agent. In accordance with the invention, a screw is incorporated in the plastic body of the appliance, in particular in the occlusal portion thereof. The screw is oriented substantially vertically when the patient's head is in an upright position and preferably is positioned over the first molar. A thin layer of plastic occlusal to the screw maintains the integrity of the seal between the plastic body and the tooth. This thin layer of plastic is compromised when the screw is activated, such as being turned or rotated by an Allen wrench type tool, thus breaking the bond or seal between the plastic body and the tooth. The appliance lifts up in a manner similar to a car being lifted up by a screw type jack.
