In order to obtain an effective closure of the anterior residual fistula following cleft palate surgery in case undergoing orthodontic treatment with brackets and arch wire, a new type of obturator seeking for its maintenance support to the remaining deciduous canine was invented. Its supporting system is constructed of a full cast metal crown for the palatally displaced deciduous canine as an abutment and the special clasp generating retaining force in cooperation with the metal crown. A case presented in this article showed an effective obturation and marked improvement in voice quality with this system.<BR>The high points of the system are summarized as follows;<BR>1) the remaining deciduous canine as an abutment for the obturator is available.<BR>2) the system does not interfere with simultaneous orthodontic therapeutic procedures.<BR>3) the patient can obtain a smooth and comfort environment for speech, since the supporting system between the abutment canine and the obturator can be designed to be small enough.
