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.
