Patent ID: 7252668

Claim:
A vertical alveolar osteogenesis microdistractor device comprising: a translating bracket with a cylinder, a fixed bracket with a chamber with an aperture, a distraction screw, lateral pins for fixating the translating and fixed brackets to an underlying bone, and a guiding rail connecting the brackets and extending posterior and parallel to the distraction screw, wherein the aperture is smooth and not threaded, wherein the distraction screw is turned through the cylinder of the translating bracket and placed into the aperture of the chamber of the fixed bracket, the aperture of the chamber being adapted to allow the distraction screw to be inserted and turned freely in the chamber, the distraction screw being shaped such as to allow its removal from the fixed bracket through the aperture and from the translating bracket, wherein the chamber of the fixed bracket and the rest of the fixed bracket are entirely located at an anterior side of the translating bracket, wherein the distraction screw, the cylinder, and the chamber are located at the anterior side of a surface defined by the brackets and the guiding rail in the assembled state of the device, such that the distraction screw, the cylinder, and the chamber do not interfere with the osteogenesis site, and wherein the posterior orientation of said guiding rail relative to the distraction screw is such that the guiding rail is between the screw and a patient having the underlying bone.
