An interim obturator prosthesis is a temporary prosthetic implant used to close the cavity created in the mouth after surgical resection of a part or the whole of maxilla, or upper jaw bone. The provider applies a substance that conforms to the patient’s intraoral structures in order to form an impression, or negative imprint, from which a mold will be built.
