“…In the design of the clasp assembly, it is essential to adhere to fundamental principles such as ensuring a passive fit, encircling the tooth properly, and providing stabilization. 6 However, in cases where patients have extensive palatomaxillary defects, the stability and retention of the obturator may be compromised significantly. This can be due to reduced bone support or the absence of a terminal abutment tooth for long-term clasping.…”

“…These include magnets, snap-on (friction type) attachments, acrylic buttons, retentive clips, and implants. 6 Implants are particularly effective in reducing prosthesis movement, preventing rotation, and promoting axial loading. When obturators are retained using implants and a cast metal framework, their design and weight may need to be adjusted accordingly.…”

The prosthodontic care for palatal defects is crucial for effectively closing oronasal communication in patients and enhancing various aspects of their oral health. This includes improving masticatory function, speech clarity, aesthetics, and overall comfort. Maxillary defects often arise as a result of surgical interventions for conditions like malformations, neoplasms, or traumatic injuries. In such cases, the primary objective of employing an obturator is to close the palatal defects that result from maxillectomy procedures, with the ultimate aim of enhancing both speech and masticatory function. This article presents a comprehensive case study highlighting the prosthetic rehabilitation of a maxillectomy defect resulting from osteosarcoma. The rehabilitation approach incorporates the use of a hollow bulb obturator, showcasing its transformative impact on the patient's masticatory function, speech clarity and aesthetics thus enhances the patient's quality of life.

Fabrication of a hollow bulb prosthesis for the rehabilitation of an acquired total maxillectomy defect

The prosthodontic rehabilitation of maxillary defects is a challenging and demanding task which requires careful pre-surgical and post-surgical planning. Maxillary defects can be congenital or acquired. Acquired defects include those following trauma or surgical treatment of benign or malignant neoplasms. A prosthodontist encounters problems such as absence of support, poor retention, and lack of prosthesis stability in treating these patients. The present case report describes a procedure to fabricate a definitive hollow bulb obturator prosthesis for the rehabilitation of a total maxillectomy defect.

“…However, in cases with large palatomaxillary defects the stability and retention of the obturator could be significantly compromised because of the diminished bone support or if terminal abutment tooth is absent, for long-term clasping. There are different types of retentive aids that are used for the conventional hollow-bulb obturator prosthesis such as magnets and snap-on (friction type) attachments,5 acrylic buttons, retentive clips and implants 6. Implants reduce prosthesis movement, prevent rotation and encourage axial loading.…”

Odontogenic tumours involving the maxilla or mandible are usually treated with surgical resection. To prevent recurrence, extensive surgical intervention might be carried out leaving the patient with anatomical defects. However, rehabilitation of such patients with an obturator can improve function, facial form and social acceptance. In this case, we have evaluated the different designs and techniques of fabrication of an obturator prosthesis used for the rehabilitation of a hemipalatomaxillectomy patient. A 40-year-old man presented with a loose fitting obturator prosthesis. He had undergone hemipalatomaxillectomy for the treatment of an ameloblastoma 2 years earlier and had been using an obturator prosthesis since then. Hollow-bulb obturator prostheses were fabricated using two different methods, the lost salt and open lid techniques. The obturator prosthesis fabricated with the lost salt technique weighed less than the patient's old obturator. But the obturator fabricated using the open lid technique did not only considerably reduce the weight of the prosthesis but also improved health, function, aesthetics, phonetics and quality of life in this hemipalatomaxillectomy patient.
