ABSTRACT:
An Orthopedic Pressure Appliance is adapted to be retained in the mouth with resilient wires extending therefrom for attachment to a headcap by elastomeric means for urging the appliance against the maxillary teeth. The upper surface of the appliance has a posteriorly upward sloping flange for engaging the gingival third of the labial surfaces of the anterior teeth and a posteriorly upward sloping surface for supporting the incisive edges of the anterior teeth. The labial-buccal flange tapers downwardly and posteriorly away from the anterior portion thereof to prevent impingement on the gingiva and alveolus. A substantially flat and deep lower surface is provided to avoid entrapment of the mandibular anterior teeth.
