A method and apparatus are provided for changing the form of the jaw and facial bones of an adult patient that did not develop fully during childhood. The method utilizes a device having a plate body with an expansion screw that fits within the mouth of the patient; flap springs that project from the plate body, and an overlay extending from the plate body. The device is placed within the mouth of the patient so that the overlay is in a position between at least two opposing teeth. In this position, opposing teeth contact the overlay during function (e.g. swallowing). This intermittent, unilateral application of force to the facial bones causes these bones to further develop, positioning out of place teeth into more proper positions, and inducing a more symmetrical and enhanced appearance of the face, as well as increasing the airway space behind the jaws. Concomitantly, the flap springs gently press against selected teeth that are out of alignment in order to guide those teeth into place. Simultaneously, the expansion device maintains these forces on the teeth, while assisting the jawbones to expand to accept the teeth in their proper position. The expansion device can be adjusted by small motors under the control of a microprocessor located on the body plate based on readings from sensors on the flap springs. The expansion device can be adjusted by remote signaling, using a global position satellite technology and global position coordinates.

A method and apparatus are provided for changing the form of the jaw and facial bones of an adult patient that did not develop fully during childhood. The method utilizes a device having a plate body with an expansion screw device that fits within the mouth of the patient, flap springs that project from the plate body and an overlay extending from the plate body. The device is placed within the mouth of the patient so that the overlay is in a position between at least two opposing teeth. In this position the flap springs press against selected teeth that are out of alignment in order to urge those teeth back into place. This force on the teeth causes the jawbone to expand to accept the teeth in their proper position(s). Also, the device is arranged such that the opposing teeth contact the overlay during swallowing, which causes the patient's facial muscles to intermittently pull on the facial bones. This intermittent application of force to the facial bones causes these bones to further develop toward a symmetrical appearance of the face and the positioning of out of place teeth/tooth into proper position. The device can be adjusted by small motors under the control of a microprocessor located on the body plate based on readings from sensors on the flap springs.

Tunnel bone grafting according to the proposed method can be used when an individual has a facial bone defect due to periodontal disease, cleft palate or trauma. The proposed method can be utilized for implant placement, it reduces wrinkles and supports facial muscle in order to make the individual look younger. The method can also be used to create a thicker alveolar ridge in order to stabilize full dentures or partial dentures. Its advantages over conventional guided bone regeneration techniques is that the proposed method is minimally invasive and lessens trauma to patients, prevents soft tissue opening, and reduces surgery time. Specifically, it minimizes the incision size and thus reduces trauma to the patient. Further, this reduces the risk of complications, including excessive bleeding, due to the minimization of the incision size. There is also considerable reduction in post surgery swelling using the proposed method as opposed to conventional techniques.
