Abstract: This invention is an intra-oral device (appliance) that will assist a user with weight loss by physiologically stimulating appetite suppression. This intra-oral device is a thin, molded acrylic or plastic plate that extends beyond the junction of the hard and soft palate (vibrating line) and is retained in place by wire clasps around selected teeth. The intra-oral appliance resembles a tooth retainer worn by post-orthodontic patients (after braces are removed); however, the shape is distinctly different, with a portion of the acrylic plate extended beyond the junction of hard and soft palate. When the plate extends past the vibrating line into the soft palate area, it impinges on an area of the oropharynx where a partial-gag reflex is located. The Vagus Nerve (Cranial Nerve X) is primarily responsible for upward movement of the soft palate and it is known to be related to appetite and anxiety centers in the medulla of the brain.
