Abstract

The described embodiments relate to a transport prosthesis and a distraction device, which is surgically implanted against a bone, for the purpose of growing new bone through the process of distraction. The transport prosthesis is designed to be affixed to a patient'"'"'s jaw to support the distraction device. The distraction device comprises a screw mechanism that attaches to a threaded post, which extends through tissue from an onlay plate that is surgically placed on the alveolar bone. After a brief, latent period, the screw mechanism is then activated daily until the desired amount of new bone growth is achieved.
