  • three way screw expanderOrthodontic Three Way Screw

    3-Way Appliance

     The 3-way screw is used to widen and well and lengthen the arch. The anterior section

    will drive forces forward using on the incisors. Alternatively, we can incorporate three

    individual screws, one to widen and two following the sagittal plane to distalize the

    posterior section. As with any expansion appliance, we recommend maximum retention

    with Adams clasps on the 6’s (if erupted) and ball clasps between the pre-molars. You

    can also incorporate a labial bow to control the anterior incisors and a posterior bite plate

    to disarticulate the arches providing additional anchorage for the upper appliance.

  • fan-screw applianceFan screw appliance for cleft

    Removable Fan Screw Appliance

    With this removable appliance, we incorporate a fan expander to widen the anterior section of the arch while maintaining the molar width. We suggest Adams and ball clasps maximizing retention. A labial bow is optional if anterior tooth control is needed.

  • Upper sagittal with posterior acryliclower sagittal appliance

    Sagittal Appliance

    The Sagittal appliance is used to lengthen the arch by distalizing the molars or driving the anterior section forward. This appliance is often used to alleviate crowding. We install expansion screws along the sagittal plane and parallel to the left and right side. You can also add a screw to either side. As with any expansion appliance, we recommend maximum retention with Adams clasps on the 6’s (if erupted) and ball clasps between the pre-molars. You can also incorporate a labial bow to control the anterior incisors and a posterior bite plate to disarticulate the arches providing additional anchorage for the upper appliance.

  • shammy-spring distalizing applianceShammy spring distalizer

    Shammy Appliance

    The Shammy appliance is used to distalize the molars to prevent the need to extract premolars. It is recommended to incorporate an anterior bite plate to disarticulate the posterior section to aid in eruption. Our standard spring is .0215 x .028 yellow spring wire which slightly extends past the mesial buccal section of the tooth. This design can use an expansion screw or bilateral springs and it’s recommended to clasp all available teeth with Adams for maximum retention.

  • Upper Transverse ApplianceLower transverse appliance

    Transverse Appliance

    The transverse appliance is used to widen the upper and lower arch to correct bilateral cross bites and anterior crowding. It is recommended to have maximum clasping because of the forces generated from the screw. As with any expansion appliance, we recommend maximum retention with Adams clasps on the 6’s (if erupted) and ball clasps between the pre-molars. You can also incorporate a labial bow to control the anterior incisors and a posterior bite plate to disarticulate the arches providing additional anchorage for the upper appliance.
