A temporary prosthesis for an edentulous patient following a maxillary resection

The primary advantages of using a hollow silicone bulb obturator on the temporary restoration are: (1) it permits the placement of the pliable bulb into greater undercut areas of the defect, thus providing better mechanical retention and seal for the obturator; and (2) the inherent rubber-like qualities of the material tend to resist sliding and skidding of the restoration.
