    "inventor_name": "Theodore Belfor",
    "publication_year": 2008,
    "device_name": "Homeoblock Appliance",
    "goal": "Reverse aging signs and improve facial symmetry by expanding jaw and facial bones while straightening teeth.",
    "problem_addressed": "Under-developed jaw/facial bones in adults that cause crowded teeth, facial asymmetry, reduced airway space, and perceived aging.",
    "concept_summary": "A split-palate orthodontic appliance that uses an expansion screw, flap springs, and an overlay to intermittently apply mechanical force to the jaw bones during functions such as swallowing. The device may be motor-driven and sensor-controlled, stimulating muscle activity and mechanotransduction to remodel bone, expand the dental arches, align teeth, and enhance facial aesthetics.",
    "detailed_description": "The appliance consists of a plastic (acrylic) plate body in two halves joined by an expansion screw, flap springs that press against selected teeth, and an overlay that prevents full jaw closure. A micro-motor (or manual screw) adjusts the separation of the plate halves, while sensors on the springs feed force data to an onboard microprocessor that can auto-adjust the motor. The device is worn at night; the patient manually turns the screw weekly to keep up with bone widening. By intermittently loading the periosteum during swallowing, the device aims to trigger bone remodeling via the functional matrix hypothesis, increasing airway space and improving facial symmetry.",

        "Each week the patient turns an expansion screw on the appliance to keep up with the widening of the bones of the dental arches.",
        "The intermittent application of force to the facial bones causes these bones to further develop toward a symmetrical appearance of the face.",
        "The device can be adjusted by small motors under the control of microprocessor located on the body plate based on readings from the sensors on the flap springs."
