“…Thus, a closed bulb obturator was planned to close the defect in this patient. Numerous methods have been introduced for the fabrication of hollow‐bulb obturators, including the use of materials such as sugar, salt, ice, and putty materials . Chalian and Barnett advocate the placement of an acrylic resin shim, whereas Tanaka et al suggest the incorporation of polyurethane foam into the defect area of the prosthesis to create the hollow portion of the obturator .…”

The most frequent type of treatment for patients diagnosed with a malignant neoplasia of the oral cavity is surgical resection of the tumor. Ablative surgery may be followed by a reconstructive phase, in which the surgeon may choose between local flaps, nonvascularized bone grafts or free vascularized flaps to close the surgical site, depending on the general conditions of the patient. Esthetic and functional results are challenging to achieve for the prosthodontist, as variable amount of hard and soft tissues are removed. This report describes the fabrication of a two-piece hollow obturator for a 19-year-old patient who underwent wide surgical excision of the osteosarcoma of the maxilla and was rehabilitated to function. In this case, the surgical site was covered with submental flap, and the second piece of the obturator provided fullness to the lost malar prominence.

“…Apart from this, when we look into the history of bulkier prosthesis reduction in prosthesis weight also have been tried by making the denture hollow. Such weight reduction approaches have been achieved using a solid three-dimensional spacer including cellophane wrapped asbestos, 4 silicone putty, 5 modeling clay, 6 plaster index, 7 salt 8 or thermoplastic splint material 9 during the laboratory procedures which are removed later to provide a hollow denture base. Parel et al 10 and Schneider 11 have used ice, sugar in the defect portion during processing and later removed by creating holes after processing.…”

Case description: A 60 year old female patient presented to Department of Prosthodontics, CODS, BPKIHS, Dharan with a chief complain of loose obturator. History revealed that patient had undergone partial maxillectomy for squamous cell carcinoma 7 years back. The patient also has been wearing obturator which was loose when the patient reported to the department. On examination, the site of surgery was the maxillary right buccal sulcus area and a part of the hard palate including teeth number 11, 12, 13, 14, 15, 16, 17. The presented defect situation corresponded to a Class I situation (resection performed along the palatalmidline) according to the Aramany classification of defects. The surgical site showed complete healing. A hollow-bulb obturator was fabricated for rehabilitation of the defect.Conclusion: The extensive surgical procedures necessary to eradicate cancer of the head and neck and to prevent local recurrence or regional metastasis often leave extremely large physical defects which present almost insurmountable surgical difficulties in restoring acceptable function or esthetics. The prosthesis rehabilitated the patient in terms of function by providing better masticatory efficiency, phonetics by adding resonance to the voice, hence improving the clarity of speech and also improved the esthetics of the patient.JCMS Nepal 2014; 10(4):32-36

“…The application of a hanging laminating molding device type used in this study made fabrication of a completely unified hollow obturator model possible. Although various methods of fabricating closed hollow obturator prostheses have been previously proposed 7,[18][19][20][21][22][23] , certain issues remain, such as in the joined part in the hollow portion and the complex nature of the procedure requiring a certain level of expertise. Therefore, a simple method was devised using a laminate-type photo fabrication 3D printer with photocurable resin to fabricate hollow obturator.…”

Fluid accumulation in the hollow spaces of obturator is a continuing problem when fabricating hollow obturator prostheses using the conventional method. To address this problem, the three-dimensional (3D) digital technology was used to evaluate water absorption in the inner hollow obturator spaces. Solid and hollow obturator specimens were fabricated using a 3D printer with photocurable resin. Then, the hermeticity was examined by leak testing. These specimens were immersed in distilled water at 37°C. Each specimen was weighed every 24 h for 120 days, and weight changes between each group were compared. Water accumulation in the hollow obturator was not visually observed. Although water absorption was significantly higher in solid specimens, the weight increase rate was also significantly higher in hollow specimens. Applying a laminating 3D photo fabrication made the fabrication of a completely unified hollow obturator model possible.
